Are all of you using the permeate with a ASO valve or did you remove the ASO valve?? Has anyone measured tank pressure ??

YES you need the ASO Valve. The ASO valve controls the water flowing into the RO system once pressure drops in the reservoir tank. In theory the city water pressure should be enough to close the ASO valve but might not. I purchase the permeate pump to compensate for the lower city water pressure and it works like a charm. The system takes a half to a third less time to refill saving water and time.

People who say that the pump will operate as its own shut-off valve are right, in that it does stop allowing waste flow to drain when the RO membrane is not producing. However: Without the ASO valve, your RO system will kick on as soon as you open the faucet and tank pressure drops compared to line. Whether this is a problem depends on how much water you take at a time. Every time you fill a glass, the RO system will do a start-stop cycle. Unless the unit is in constant use, at the start of each cycle the water quality out of the membrane is going to be significantly worse than you would normally expect. There's very little you can do about this, it's a characteristic of RO membranes. The only solution is to reduce the number of start-stop cycles per amount of water produced. A regular ASO valve will accomplish this, in that it has an interval of pressure where it operates and will run your RO unit to fill your tank from, say, 1/2 full to 3/4 full. Since permeate pump-equipped RO systems don't care about the pressure differential across the RO membrane anymore, an ASO valve designed for a permeate pump system will have a different setpoint, and will run your pump when your tank is 3/4 to 7/8 full, for example. This still keeps the number of cycles down (the system will not inject sub-par quality water into your tank every time you fill a glass) *and* lets you take advantage of the higher initial flow pressure out of your tank and the (somewhat) increased storage quantity that comes with it. Hope this helped.

Traditional asv can be used or you can take advantage of the pumps ability and use a 90% shut off. However we usually build them without a shut off as the pump itself will act as a shut off when tank is full. This will actually give you the best performance overall. Te pressure in the tank will not be any higher than your incoming water pressure. For instance a standard asv shuts off when tank reaches 60% of line pressure, without, you would get close to 100% line pressure.

Using pump with no ASO. Pressure generally between 30 to 35 psi. Can now make ice with pump.

Since I added this pump my RO system my water production rate has improved to such a degree that I no longer desired to geek around with my system any more and did not replace or delete the valve or measure tank pressure. I am satisfied with this pump! had to hook it up twice though so pay very close attention to the tube routing installation diagram if you do it so you won't have the same fright as I did. G'luck!

I had problems. A lot on pressure on piping. Had to pass an extra pipe for black water to store it in main tank instead of wasting it (like a traditional RO)!

You might want to check the pump for any kind of blockage,it does not come rushing our with any kind of pressure.I thought there would be more pressure coming out after I installed mine as compared to other filters I have had in the past...that is not the case with this filter/pump set up.

Mike: silly question, but did you give the filter an extra push, plus push in the top rubber gasket some more to expose the thread? If this fails then the filter is too long. In that case I would be making an extended threaded mounting post. Or a special nut with a reduced diameter that will go inside the filter and catch the thread. My 10 gallon Craftsman has a 7/16 NC thread. I have the capability at home to manufacture these fixes, but if you do not I am at a loss for other solutions. Hoe about a recessed cup with a flange, then cut a bigger hole in the filter rubber and use a 7/16 nut inside the cup.

hi this is erin johnson,,i'm the on how installed the tanklees...use 2/d-pull 40amp-2of them ,i used #10 as my ground, so use #8-mm2-thhn two of them for each sq-hom breaker..i'm vary happy with my work and the unit..a lillte low on psi on the outside but well off for sure! we have save 12.5 % on bill ..from erin johnson..email is ejcooleaglesflyhigh@yahoo.com

Do you bleed the line before removing the tank? I shut off the tank then press the trigger until no more air comes out. I use a remote coil with a quick connect. Doing this I've never had air seep afterward Hope that helps

The tank might need air. Turn off supply to r/o. Expel all water from tank. Put 7 psi of air in tank. Check if valve leaks by putting soapy water on valve.

Seems to be 2 slightly different valves, I had both and both were bad so not a problem for me, ordered one then the other.... get the tva2 for yours. Tootles... Wade

Once I applied this in line filter, it drasticly reduced my air pressure. So I just canned it. I apologize for bit directly answering your question. But it's somethig I wish I knew prior to purchasing this item

I had trouble with that too. You have to be very careful as the alignment of it very precise. If you don't do it exact you will hit the valve and it will release water. Do this just temporary. Put the whole thing on your kitchen counter top so that you can see it closer. Do this with no water in the tank just to practice. You will see what has to be lined up to keep from hitting the valve to soon. Practice putting the tank in place. This will let you see how precise you have to be to not hit the valve to soon. Now put the unit back on the floor and go thru the motions you just learned. You got to be patient. Hope this will help you. Al

I have a similar item and it connects perfectly. Remember that the threading is backwards so you have to twist it on backwards. Make sure the tank valve is turned off, so there is no tendency for the hose fitting to be pushed away due to gas pressure. I suppose you could have a very old tank with one of the smaller fittings, if so, you should upgrade. I hope this helps.

Robert is correct, I was wrong. It seemed at the time I had a little more of flow but it is impossible. If you have a pressurized tank there should be a shrader valve on the tank to check the air pressure of the bladder inside of the tank to boost water pressure, you may be low on pressure in the bladder. You may need to use an air pump to raise the air pressure but be careful, I don't remember what the pressure should be. Check with Watts Premier web site.

I returned mine. Could only get 130 PSI out of it. Connector did not leak though.

have you had better luck with your filter? Just received mine, have hooked it up but can't get suction. Have primed it, filled the tank first, as mentioned in another post. Have not shortened the length of the tubing as yet. Any advice?

Did you put the fine film of oil on the lid? I originally missed that on my AA. I have only gotten a slight steam leak once or twice, but it seemed to stop when I got up to pressure. Sorry I can't help more.

I would make sure you have a vent on tank. I noticed on mine with a gravity feed it would drain very slow so I installed a breather. Worked great after that.

Prob better to go through your gas first. Sounds like you have a rusty tank tho. It'll def work for your problem
