Question about Plumbing

1 Answer

Sloan valve not flushing correctly. when I flush the toilet it seems like there's not enough pressure to even clear the bowl. I've changed the diaphram, vacuum breaker and bowl but nothing seem to work. I had a technician from sloam come out and take a look at the valve and the only thing he can come up with is that the water line is not sized properly. The line size is 3/4'' and I teed in a 1'' line for the bathroom. The distance between the fixture and this connection is about 25'-0''. What should I do to fix this problem for once and for all.

You have a choice of either running a 1" line to supply the valve, or installing a booster pump to increase your system pressure. Or, you can install a regular tank type toilet with a pressure vessel in the tank. This is a code approved toilet for commercial applications.

I would change the toilet as it probably presents the least amount of labor in changing the piping.

SOURCE: commercial tankless toilet won't flush

There is a screw adjustment that basically allows so much water by then the valve shuts off. Located under the cover. If you already tried adjusting this then replace the diaphram. Plumbing shops will have the kits. Pretty simple to fix. Good Luck have a Great Day. Please give a 4 THUMBS UP if this free answer was helpful. THANKS

SOURCE: is there a way to adjust the amount of water in

There is only one way to do this and that is to increase the water level in the tank. To explain the flush valve in the tank fills both the tank and refills the bowl at the same time if the valve runs longer to fill the tank it will at the same time put more water into the bowl. Now having said that the bowl will only hold a set amount of water before it starts running out into the drain. If the tank water level is at the line marked in the tank it will most likely not do much good to raise the level beyond that point and if the toilet you have is a 1.6 gallon flush tank I am sorry but learn to live with it.

If water is constantly running into the cistern you will need to change the rubber washer in the shut-off valve. Washer kits are available from most DIY stores. Turn the water off at the isolating stop-****. Unscrew the end of the inlet valve (watch out that any springs etc. don't ping out) change teh washer and reassemble in reverse order.

How do I lower the water level in the toilet bowl of a Slone Flushmate? It keeps getting higher, little by little after each flush.

The flush valve may be defective but some tinkering with the refill level setting may work.

Flushmate 503 sprays water out of top of tank, apparently coming for under the flushmate system. The valve doesn't seem to leak. Iahve pressure tested it.

Turn off the water supply at the wall, flush the toilet to relieve the pressure inside the Flushmate, and call Flushmate Consumer Services at 800-533-3460 M-F, 8:00 - 4:30 ET.

They'll need to know the serial number and approximate date of installation of the Flushmate.

You could alos fill out a confidential "contact" form on the contact page of the Web site,

If yu need to use the toilet in the meantime, you can "bucket flush" it by pouring 2 to 3 gallons of water into the bowl. This will generate a standard siphonic flush and won't give you the pressureized extractiopn but it will keep the toilet usable until a Flushmate support tech can diagnose the issue and provide a resolution.

Good luck!

We are an info Center for a community. The pool company came out yesterday & cleaned the pool using most of the water pressure. since they left the toilet will not flush. is there an easy fix to...

Believe it when I say the pool is not connected to the toilet.

You are not clear as to what actually happened, I presume the pool company came in and attached a hi-pressure cleaning device to your water supply. As such, they were definitely using your fresh water supply which should not have made much difference on the pressure. You say it did, ok. When the pressure went down in your water line, there is that possibility that the toilet would not fill as fast as when full pressure is available but that should only be a matter of minutes not hours, particularly if your toilet is a tank type.

You say you are in a community center, I must presume you have at least a one inch water line into your building and probably much larger, you may have a tankless toilet with a meter valve ("Sloan") on it - meaning you have enough water in your water system to support a direct flush and do not require a tank.

It could be that scale inside your pipes was disturbed by the high flow of water and the scale found its way to your "Sloan" valve, blocking the flow of water. To check this, turn off the water supply to the toilet, remove the top of the valve and clean it. Reassemble and turn the water back on.

I hope this works for you ... thanks for your quesiton @

Just hooked up new pressure asist tank & bowl,turned on water to it,and it want flush.what i mean about want flush, is it will flush but water does'nt go down,as if it's not staying open long enough.

Sounds like you have a clogged drainline or vent-stack. Fill a large bucket with about three gallons of water and dump it quickly into the bowl. If the drainline/vent is clear, the toilet will "flush" like a gravity toilet and the water will drain from the bowl almost as fast as you can pour it in.

If the water level in the bowl slowly rises (as if it's about to overflow) and then slowly drains, you have a clog somewhere.

All toilets, regardless of their flushing mechanism, require a clear, unoibstructed drain/waste/vent system to extract waste.

If the toilet "flushes" with the bucket of water, you may want to call Flushmate tech support (the number is on top of the tank) or check out the installation and troubleshooting videos at

Hope this helps.

My flushometer toilet will not stop flushing. The

Try checking the water pressure. If it has dropped too low then the valve will never re-seat properly. Ideally over 90 psi.

Flush twice and/or hold the flush valve down while the refill valve continues to run water into the bowl.
