Leaks behind coupling in 6 weeks
581806
Purchased two of these 6 weeks ago. I use them 10hrs a month and one of the couplings is leaking behind the crimp causing water to fill up the outer liner with water making the hose bulge. 30 day change policy will not allow me to return. I'm out $100.

As is it leaks like a sieve.  Half of the o-ring containintg, screw tightened joints were leaking.  Once I disassembled everything and thoroughly wrapped all threads with PTFE tape things stopped leaking.  My other gripe is how in the hell is tailpiece supposed to connect to my sink drain pipe?  Neither were threaded.  I eventually strapped everything in place with metal wires, stretchy silicon tape wrapped the joints, and then thickly caulked everything.

I was racking my brain and googling and utubing to figure out how I am supposed to make this connection.  Do I blame the drain for not having threads?  I don't know, but this little shortcoming delayed my use of my sink for two days: one day to get the silicon stretchy tape and another day to let the caulk dry.

Everything fit into place quite well in the limited space I had under my sinks, but the stupid leaking and no way to connect the tail piece really grinds my gears

I had this installed in November, everything was wonderful. Unfortunately I was out of town and when I came home the faucet was leaking all over my floor. The 2 copper pipes going into the part by the handle became rusted and water leaked out. So I had to replace it. Not willing to replace it with another of the same.

Initially this worked great and I was expecting to get at least several years of use.

UPDATE- 6 months later the metal component still seems to be in great shape- HOWEVER- the internal coupling where the hose attaches is PLASTIC and snapped right off.  Unrepairable.  Why make a sturdy metal sprinkler with a weak internal plastic coupling ??????

I bought this 6 months ago and just started using it in the spring. I thought it was the best hose I ever had up until last week when I found two holes in it. I've probably used the hose 6-7 times and now it already has two leaks. Perhaps if you are going to use the hose in a pillowed room where it can't rub against anything that would commonly be found in a yard, then you'd love this hose. But what good is a hose if it leaks in the first 6 months of very light use? I also tried to repair it with silcone tape, but it failed, probably due to the way it shrinks when you depressure it. it's an expensive hose for something that doesn't hold up very well.

Installed 6 months ago and now appears to be leaking from around base of handle where it rotates over the round /curved part of the base, especially when handle is lifted all the way up (full pressure).  Easy fix or is it junk already?

Leaked water around the knurling. I looked to see if it was come from the threads but it was from the knurling

This is a very low quality part, the solenoid works ok, or at least it has in the month it has been installed.
It started leaking almost immediately after we installed it.
The issue is the supplied fitting with the shutoff or the solenoid body. The problem is the fitting bottoms out in the solenoid before it gets tight enough to seal. Even with the use of sealant on the threads. This is a pipe fitting and the threads should seal.

It is now 8 months later and the solenoid has failed.

Works beautifully for about a month then develops pinhole leaks. I have so many leaks at the connection, it's more of a sprinkler there.

Everything-Aftermarket  was the seller

Failed after 6 months with leaking. Had to tow to garage because 2008 Saturn Outlook is too hard to steer without power steering. May just be a defect but I just put another one on order with Prime. Seller I bought from don't sell this item anymore and also won't return my emails about Warranty. Cost was cheap but not worth it if you have to tow and fix 6 months later. This cooler doesn't go out very often as it rare fix so I am leaning to bad product design. I will keep you up to date on the warranty. I am out well over $300 just to have another one put in.

My faucet, which had the Yellow Grohe Quick Coupling, broke about one centimeter below the orange band, which resulted in water spraying all over the inside of my sink when I turned on the faucet. Evidently, this is a design issue with this coupling and it is notorious for failing around the 5 to 7 yrs after installation (from what I read online). The part was very easy to disconnect and I ordered a replacement yellow disconnect immediately.  However, in looking on-line I saw other Grohe quick couplings and could not find out any information regarding the difference between the yellow and  green Quick Couplings or their specifications except the yellow was for Faucets manufactured before 2005 and the green was for 2005 and later faucets.

So I dug a little deeper and found a parts supply website I asked the following questions regarding the difference between the green and the yellow quick coupling to a Grohe part supplier: Is there a difference between the Grohe Yellow Quick Coupling (#46 138) and the Grohe Green Quick Coupling (#46 315). That is, are they interchangeable? Or is there a difference in the amount of water they allow to flow through them? Or is it only that the green is a newer quick coupling redesigned to fix a design flaw with the yellow coupling (which is notorious for breaking in 5 to 6 years)?

The response I got was the following:  "Thank you for your question! The Grohe 46 138 is the older version of the Grohe Green Quick Coupling (46 315). These are interchangeable, so you can use either one. Noting that you are aware of a particular design flaw on the 46 138, I would advise using the 46 315 just to make sure you are getting the newest available part."

I actually bought both parts, and the yellow is slightly longer (which does not affect the functionality of the connector from anything I can detect, but that could be what causes it to be weaker).

So a long story short, I purchased the green quick coupling (which costs a few dollars more) and installed it.  It installed easily and I have had no issues with it leaking and all seems to be working fine with it.  I cannot say whether it is a better part yet, but I am betting that the shorter design has made is structurally more sound and I am hoping that it will not fail as quickly as the yellow coupling did.

Regardless of the above, given a part like this that is subject to constant movement over the years, I would have expected Grohe to make it out of more lasting material (i.e., metal) that would not  break during the faucets normal life span.  It is not the cost of the faucet or the replacement part that is the issue but the damage to my cabinet and flooring from the water that built up and seeped through the floor that is the bigger issue.  Grohe should be embarrassed by this, as it does not live up to the expected standards for which I believed Grohe was manufactured.

In the future, if I purchase another Grohe faucet, I will look to see what parts are plastic and if they still have this quick coupling made of a material that will not last then I will move on to a better faucet.  It is not worth risking the thousands of dollars in dammage that can easily occur from a faucet that pours water into you cabinets.

These couplings suck! They constantly leak, I pull them apart and refit then they might stop leaking, then another one leaks.

Nice unit, but within six months the hand held shower unit is leaking at the shower end. Tried teflon tape on the threads, but it still leaks. Not sure if it's the hose or the shower wand that is the culprit, so will have to order both to ensure I get it. A bit disappointed in a costly unit doing that so soon.

Well called American Standard 800# with no luck. Gave them the model number listed on Amazon, but it doesn't match anything on their website???? No help at all. You mean to say, you can't pull up your product by your own description?

Last American Standard product I'll buy.

The system was leaking on preinstalled connection (see picture for details) will try to to replace failed (top) part.
Update: have requested replacement today, will report once top part received and replaced.
Update 7/22/2017: Have received new part and replaced failed one. No leaks after replacement. Testing for 3 days - all good.

Bought this model about 18 months ago and has been used very sparingly.  The compressor works fine, but an air leak developed from where the hose connects to the body.  I called Home Depot (which owns the Husky brand) and they informed me that there is no way to replace the hose and the connection.  In my mind, this is a design flaw - too flimsy to begin with, and no option to replace a bad hose.  The connection should be a lot sturdier if it is not meant to be replaced/repaired.  I do not recommend buying this product.

Installed with new fittings but it leaks. I have to send it back to Amazon. Cannot be resold.
