I have an old fluidmaster where the diaphragm is by bottom of tank, replaced the diaphragm at the bottom, it filled once after fixing but wouldn't refill again. Ideas as to what else could be wrong?

I have not always had good luck replacing the rubber diaphragm and then working for very long. That's why I switched to the Korky brand. So far so good, but I did not buy the cheapest one. I bought the one that the clerk at Lowe's said was the most popular one sold.

If I recall correctly when I purchased mine well over a year ago I had a leak problem with the drain valve at the bottom of the tank. Called Rollair and they shipped me another valve and that fixed the problem. The compressor may have a small issue to fix but in my opinion it's well worth it. I'm considering buying another one for back up.

I could not tell i never received the right pump from them. so i bot ells where. i would check to see if there is a reset bottom on it. if not send it back

I that happened to me.. basically you over filled it and the pressure pushed the top tank up.... fill up to the top of filter, or just below. It's good to go

That was a symptom I had when there were either air bubbles in the system or an obstruction somewhere. Eventually the valve, or whatever the mechanism was internally, froze in place and it wouldn't generate pressure at all, despite clean system. That's when I returned it to Costco, only a year old. Went with a more expensive gasoline unit instead, much better power for cleaning and longevity.

So they just contract and stay contracted? Has the pump worked for you before or is this the first time you're using it? First, I'd make sure all the parts are connected properly (push firmly at each connection), especially the white valves underneath the flanges. If that doesn't help, inspect each part of the kit (valves, diaphragm, tubing) for any tears or holes. Do you have any spare parts you can swap out to see if it's one of your parts? If none of the above work, try using the manual pump with the kit for now and call Customer Service. It may be your motor. :( I had problems with suction a few times but it was always the result of forgetting to properly assemble some part, probably because of sleep deprivation. Hopefully it starts working for you soon!

Ok, first I never fill totally full the tank, only 80% maximum. Second, in your case you should contact the seller no matter which part has problem. I had leaking problem in the filter machine before. They helped to solve it. The seller has very good customer service.

One of your pumping pistons isn't re-extending for the next pump and so it's only pumping at half pressure. That's how mine died, I haven't figure out a fix yet.

The fill valve assemblance has a small flat seal that presses against the fill port when the float rises. The seal can be clean and should work again but it will only be temporary. Replace the assembly unless it is leaking past the flapper, it is very eady.

I bought 2 and one was partially filled and the other was not. It may be due to rules against shipping compressed gas, do not know. Partial tank lasted for quite a while.

Was there a defect with the old ones??. I complained about my purchase, every other day I had to refill it with air. I wld not recommended buying.

Try removing the mineral stones on the bottom. Clean the container and rinse the 5 stage filter. Refill. Should be fine

first make sure o rings are in place as instructed, could be not tight enough. You may be overfilling unit it is not four gallon it is 3 gallon in bottom tank. top tank is not a holding tank as far as I can tell because there are no rubber seals between them hope this helps

It's not likely the fault of the fluid master. I would suspect it is just reacting, as it should, to a leaky flush seal where the water exits the tank during the flush. It may not be sealing off tightly and, thus, permitting a slow leakage of the water in the tank past it and into the bowl below. As the water level slowly drops enough to a point that the Fluidmaster decides to refill the tank, you may be hearing it refill for a few seconds. If this is determined to be the problem, then replace the flush seal rubber washer or bulb (which-either your tank has). This is done without removing the tank.

I am having the same problem I even changed the diaphragm out thinking the old one was bad.

You may need to contact the company and ask them. When I first got mind, it did not flow at all so the company sent me a new dispenser (not tank) and then it worked.

While refilling, you may have inadvertently lost the very tiny white plastic bead that sits loose inside the pump assembly at the bottom of the spring piece. Same thing happened to both my units. So I used a round pinhead from a decorative hatpin. Just pulled it loose from the pin and dropped it into the bottom of pump shaft and all worked again. The bead prevents the pump from pushing air back into the soap reservoir instead of out the dispensing tip.
