Pump will not connect to bamboo tubing--Ugggh!
920619
The bamboo fountain is great. I like the adjustable feature and the nice sound coming from the water trickle. One big problem: the included pump will not work with the fountain. The problem is the connector piece, which needs to be 8mm male to male. Unfortunately, the plastic connector piece included is 8mm-10mm male to male as best I can tell. This will not work with the tubing that is included with the bamboo fountain. Sound confusing? You will see what I am talking about when you try to hook this up. Solution: buy another connector 8mm male to male. I had one from an old pump but it is a hassle to buy a brand new fountain and then learn the fountain and the pump will not work with each other for lack of a 50cent connector piece. Ugh!!!

We haven't been able to find a pump that's tiny enough to inflate the tires.  Haven't found on-line solution, either.  I will re-review if we can ever get it to work.

I tried this on my new 27.5 MTB Wheelset, new tube and new tire and I couldn't get it to inflate at all.  Neither setting, high volume or high pressure, didn't make any difference.  I must have pump at least 450-500 times but no luck.  I really wish it would have work because I really like the mini tire pressure gauge but no luck.  I've no choice but to return it after few days of trying.

I had an old Zephal pump that worked flawlessly for 15 or more years.  When the hose went bad and I couldn't find one that fit, I decided to replace it.  This Lezyne pump got a lot of good reviews, looks gorgeous, and seemed like a "last pump you'll ever buy" type of product.  I've had it less than a year, and while it works okay, it's certainly nothing to write home about.  Here are the issues:

1)  The wooden handles you see in the picture screw directly into the top of the pump.  It is not one piece of wood, but two handles that screw into a metal threaded shaft.  I noticed one was slightly loose, so I tried to hand tighten it, but it just spun around and around.  Turns out the wood on both is stripped, and they feel about to fall off.  The wooden handles should have a metal sleeve inside them so they can screw tightly to the pump.  But they don't.  I e-mailed Lezyne and their response so far has been "that's weird, we haven't seen that before".  Seems odd.  I sent them photos of the stripped handles and have not heard back.  I fixed the issue myself by putting some toothpicks inside the handles and screwing them back on (an old trick anytime you have a stripped hole in wood), but it's not a long term repair.  And even if they send me new handles, it's still a major design flaw that looks like it was done to save money. UPDATE:  They sent me a new handle that doesn't have the issue, but I'm leaving the review up because I still stand by the balance of my feedback.

2)  The chuck, while good quality, is a pain to use.  It screws on easily enough, but in most cases to unscrew it, I end up twisting the hose, which will eventually wear out the hose.  The little pressure release does little to help.

3)  About 30% of the time, when I screw the chuck on to a presta valve, it won't pump it up, just fills the hose.  So I unscrew, screw back on, jiggle around, then it starts working

4)  Other times the pressure gauge shows no pressure being added to the tire, despite the fact that it's filling with air.  So each time you stroke it, the pressure gauge goes back to zero, but the tire gets firmer and firmer.

5)  I read some comments the pump moves a much higher volume of air than others.  It sure doesn't feel like it.  Feels like it takes exactly as long to fill a tire as any other floor pump.

I'm sure there will be people who call all these issues user error, but lets be clear:  This is a bike pump.  You should be able to snap it on, pump your tire, snap it off, and be on your way.  I am never one to skimp on quality, but in the case of this pump, I don't believe "you get what you pay for".  I feel like I got a lot less.  I wrote this review intending to only discuss the handles, but as I wrote, I realize there's a lot about this pump I don't like.

Get one at the bike shop for half the money, it will probably work better.

I have not had any luck with this pump. We have had to replace parts.  This pump has been a pain!

worked for about 15 times then water would not pump up from the base plumbing through the needle.
I took the top portion apart to verify there wasn't a clog and it was clean.
Either the tiny pump that pushes water up to the needle failed prematurely or there is some valve stuck somewhere in that network.
You can either waste a whole lot of time trying to fix it or if possible return it and never buy this brand again.
I could not return mine since I shredded the receipt and threw away box.
I wasn't expecting to see problems with this for at least a year.... who knew?
Update!!!
Ok folks here's what I did to get mine working like it did when I first got it... keep in mind this is for when the water stopped pumping
up from the tank.
Air is in the pump, it's in cavitation (fancy word for air in the pump).
Put your drip cup and a 16oz travel mug in place just like your going to make coffee.
Take the gray measure basket out from the reservoir and fill the tank all the way to just under that overflow hole located at the back wall of the reservoir, going over it will have water coming out the bottom.
Take the stopper plug and put it in the water to the right of the drain hole and shake it slowly in the water to get the air trapped in the end to come out.
Now place the stopper plug in the drain hole and push down quickly and pull back up slowly, kind of like when plunging a toilet only pull back slowly.
Repeat this about 10 times to push water back in to the air bound pump, take the stopper plug out and
plug it in and try it, keep waiting until the pump has been running about a minute because water needs to travel through the tube.
If no water comes out repeat the step again up to three times.
When water comes out let it complete the cycle until the light goes out.
This could happen again so I recommend to always have water in the tank and don't let it go empty to where it sputters at the end of a cycle.
Leave the measure basket out and just add water to the size of your cup as you go.
Hope this helps you,I almost threw it in the trash.
Oh yeah one more thing, use purified water such as Nestles Pure Life to keep it build up free and for better tasting coffee.

My original fountain could not be connected to the pump. Contacted seller 3 times & was given excuses about the holidays for shipment of part. After 1st review new pump attached to top unit came & works. No water sound but read another review & will try suggestions.

Too loose to connect 1/2 tubing and when I turn on the faucet, the 1/2 tubing will pop out. Now I have to be creative by using rubberize glue in order to use this THING. Not worthed to return.

I have been trying for more than a month to get it to work. I have relocated it, primed it, lowered it, shortened the hose run, and currently have it set up as one line going into a cup to measure output and get nothing. It flashes per the setting, and at night goes into night mode but never seem to pump water. When I use the syringe that came with it to prime the pump, or turn it off and on, the pump runs for a few seconds and I get water to come through the lines, but not in normal operations. I am very frustrated. This would be a great product if it would work.

This is a replacement for the standard round tub for us. We had the round one for 2 seasons, but the pump failed. Not sure what killed it, but we had a power outage when the tub was running and after that I couldn't get the pump to run. My guess is that the heater was on, and the pump impeller or a bushing melted. Haven't tried taking it apart yet, but there are no parts listed, and Intex will only sell you the whole pump assembly (not parts). Decided to buy this model as it has the heater for the air bubble system, and thought the square shape would allow better seating for four. One other neat feature is that it has a port that will help suck the air out of the pool when you are putting it away. The warm bubbles let the pool stay warmer in cooler weather, and the square shape does allow for better seating. The cover fits tighter too. If you are setting one of these up, be sure to tighten the air fill port, my round one leaked there. I cut 1 inch foam board and put it under the tub to help insulate it. Not sure if it makes much difference, but it does add a bit of a cushion to the bottom.

UPDATE - Last fall, the heater failed. Took the tub down, found that the pool itself had water leaking into the air chamber - not a big deal, but required more time to drain the tub. Still had the old controller (from the round tub), so I pulled out the failed heater and installed the one from the controller for the round tub. When I set the unit up this spring, everything was fine (still leaking water into the air chamber though). Tub heated and operated as normal. Last week, we had a power failure again (This is a supply failure, not my house - summer storms). When I tried to restart the tub, it produced an E95 error. This indicates that the water is too hot, but it isn't. The water is air temp, it's just not heating. The pump works, and I can run that all day if I wanted, but it will not heat. Not sure what part failed this time as the temperature reads correct, but there is no heating. Called customer service to ask about design changes that may make any new models work better. I was told that I could purchase a new controller for $300, but they didn't know anything about design changes. I asked to be transferred to a manager that might b e able to help, and they said they are not able to transfer (not just unwilling, unable). So, I will NOT be purchasing another one of these Intex spas. You are better off buying a real hot tub, and saving the trouble of buying a new one of these units every other year.

I received the pump and was hoping to do a quick install.  I am using it as an in-line pump (not submerged) and so it requires that a fitting connect from a tube to the intake port.  The connector was a plastic piece and just tightening that into the pump cracked it!  Fortunately Amazon is sending me another and I hope the next pump will work.

Can not use due to unloader valve causing pressure to fluctuate every few seconds. Sometimes it goes for a full minute before acting up again. No leaks so not pulling air. Purged pump multiple times. Tried multiple hoses 5/8 and 3/4 with length no more the 20 feet. GPM from the hose is right at 4 so plenty of volume. Very frustrating!  No damage to the box but it has a bent rim. Taking it to the dealer tomorrow to see it they can get it working. I will update later and hope to be able to give a better review.

Unfortunately I was shipped one with a defective hose.  I attempted to simply inflate an inner tube without tire and it couldn't even do that...98% of air simply leaked out at connection nearest valve.  I tried another hose from another pump I had and it worked perfectly.  Also, attachment for schrader valve makes pump too long to fit on pump pegs.  Don't most if not all older bikes fitted with pump pegs have rims that fit schrader valves??  I would prefer a hose with dedicated schrader valve attachment, not another tiny attachment I will have to screw on to the presta attachment each time I want to use it.  I guess I'll have to carry that tiny piece in my pocket or bag.

i could never finagle the tubing into either of their adaptors. these adaptors are black in their youtube video, but they sent me  green ones that are much shorter than what is shown on this video. my green adaptors were hard plastic (from watching the video i cannot tell if the black adaptors are soft or hard) and could not seal around the "port" on the printhead.

 But, I was able to clean the printhead by dropping drops of cleaning solution onto each "port".  I was able to see all four colors bleed out onto paper towel that I placed on cardboard box material, which suggested to me that the blockage in the printhead was likely dissolved.

I tried all sorts of things to insert the tubing into the adaptors they provide, i heated the tubing in hot hot water for several minutes, i even sliced the end of the tubing to help me with its insertion, but nothing worked for me.

After some more attempts to use it I definitely don't get the appraisal. I got mine in 2014, but today (March 2018) I needed it for my bikes at my parents house and simply ended hating it. The body seems well built, but the important part of a pump is to be able to use it, and this thing simply doesn't work. I tried to adjust the cap as some reviewers were saying (opening one third, positioning better, etc.). I have had much better luck with my lezyne micro drive pump, and definitively recommend pumps with a screw-able chuck.

I purchased this unit in September but the adapters that came with it did not fit any of the three Moen and Delta faucets or shower heads to which I tried to connect.  I gave them specific faucet connection measurements by email (55/64 inch male with 27 thread, the Moen standard for the aerator connection).  All emails were ignored.  I talked to them by phone nearly every week and was told each time that an adapter would be sent.  It never was.  I would have sent the unit back but the company led me on until the return date was past.  Finally, last week I visited a plumbing supply shop and purchased an adapter to go directly from the 1/4 inch tube out of the RO to one of my faucets.  I cut their adapter off the tubing and connected mine.  I gave the unit a 2 rating only because it does seem to produce RO water at a rate of about 2 gallons per hour at 40-60 psi supply water pressure.  If you buy one, don't expect any support from the company.  In fact, if you get any response from the company it will be passive-aggressive, where they tell you they will help you but then just ignore you.

I just filed a return request on this pump for the second time in less than three weeks for the same problem: The airline tubing connector broke off. The first one arrived in that condition(leading me to suspect it had been returned before), the second one just broke when I moved it in the bottom of the aquarium stand. The tubing was the really flexible stuff and had been applied with an aquarium silicone lube so I know that it wasn't a stress thing, it just broke. It had been in service for about 10 days and this was the first time it had been moved.

Before it broke the unit was quiet and powerful and the variable air output is a nice feature. But that doesn't really help when you can't hook it up to your airline... :(

I'm giving up and asking for a refund. My single airstone is running very satisfactorily off the cheapest pump PetsMart sells:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Tetra-77851-Whisper-Air-Pump-10-Gallon/dp/B0009YJ4N6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Tetra 77851 Whisper Air Pump, 10-Gallon</a>&nbsp;, about 1/3 the cost of this one. I've been dragging it around for a couple months aerating buckets of water and fish bags, it gets tossed in a box with the airline attached when not in use and it hasn't broken yet.
