How To Repair Sloan Flush Valves Without Breaking Spud

Sloan flush valves are one of the most popular flush valves used across the world today. This article shares nine flushometer troubleshooting tips that may assistance you the side by side time you lot encounter a trouble with your Sloan flushometer. Review the bug and solutions below. Don't run into the answer to your question? We have dozens of model specific guides and parts breakdowns on our Parts Breakdowns and Troubleshooting Guides page.

1) Flush Length Likewise Curt

If the length of the flush is too brusque, or if the valve turns off immediately when activated, there are several possible causes. Get-go, the diaphragm associates could be worn out or damaged. Secondly,  the handle assembly might be damaged. If either of these is the case, simply replace the diaphragm assembly or handle associates. Having a low consumption diaphragm associates installed in a water saver or conventional fixture could also exist the cause of a short flush. In this instance, check the label or markings on the fixture to learn what the required flush book is. Then supervene upon the diaphragm assembly or relief valve with ane that is designed for the correct flush volume.View diaphragm assemblies and handle assemblies to discover the repair parts y'all need.

2) Flush Length Also Long

Sometimes, the elapsing of a flush can be too long. A common reason for this is that the by-pass orifice in the diaphragm may exist clogged. To resolve this result, remove the diaphragm assembly, disassemble the filter rings from the diaphragm, and rinse the diaphragm thoroughly. Exist enlightened that the size of the orifice in the by-pass is of utmost importance in the proper metering of water into the upper chamber of the valve. Do not enlarge or damage this orifice. If cleansing does not correct the problem, replace the diaphragm assembly. Read our Diaphragm Kit Guide for help finding the  best r eplacement.Some other reason for a long flush could exist that the relief valve or the within cover are damaged. Supercede these parts if and so. If a water saver/conventional diaphragm assembly is installed in a low consumption fixture, that could besides cause a long flush. In this case, check the label or markings on the fixture to learn what the required affluent book is. Then replace the diaphragm assembly or relief valve with ane that is designed for the correct flush book.  Ane more possible cause is that the line force per unit area has dropped and is non sufficient to force the relief valve to seat. To resolve that trouble, shut off all control stops until the pressure has been restored, and so open up them over again. Read our Command Stop Guide for more data regarding proper control stop installation.

3) Flush Valve Does Non Affluent

Sometimes the valve might not flush at all. Bank check to see if the control stop or the primary valve supply is closed. If they are, open them. General wearable and tear can be expected over fourth dimension, so if your valve isn't flushing, it could be because the handle associates is worn out. To fix information technology, merely replace the handle assembly, or use a handle repair kit. The same goes for the relief valve. It can get damaged over time, so it may need to be replaced.

Other causes of no evacuation:

Cause: Low force per unit area (>25 psi / i.7 bar)
Solution: Accost plumbing arrangement deficiencies or adjust control stop to increase menses pressure

Cause: Depression consumption or urinal diaphragm installed in older closet.
Solution: Install right GPF diaphragm

Crusade: Cover not properly tightened for unit using dual filtered bypass diaphragm.
Solution: Tighten cover

Crusade: Incorrect piston installed (in piston type flushometers.)
Solution: Match piston GPF to fixture GPF

Crusade: Piston lip seal degraded (in piston blazon flushometers)
Solution: Replace piston assembly

4) Continuously Runs

There are a couple of different reasons the unit could continuously run with no close-off. Start, empathize that the potential causes and solutions are dependent on whether the unit is diaphragm or piston type.

For Diaphragm Type Flushometers:

Cause: Solenoid stuck open
Solution: Supercede solenoid associates EBV-136-A

Crusade: Debris blocking diaphragm bypass
Solution: Make clean diaphragm to clear bypass orifice

Cause: Debris under diaphragm
Solution: Remove droppings

Cause: Depression pressure drop
Solution: Bank check facility/municipal line pressure level

Crusade: Diaphragm assembly compromised
Solution: Replace diaphragm assembly with proper GPF kit

For Piston Type Flushometers:

Cause: Debris blocking bypass
Solution: Clean piston to clear bypass orifice

Cause: Debris nether piston
Solution: Remove debris

Cause: Degraded relief valve seat
Solution: Supercede the piston assembly

Cause: Depression pressure level drop
Solution: Cheque facility/municipal line pressure

5) Splashing H2o

Water splashing out of a fixture can be unsanitary, also every bit unsafe, creating a moisture, slippery floor. If this is happening with your flushometers, there are two potential causes. One is that the control stop may be open wider than necessary. The other is that you may have the incorrect diaphragm associates installed in your valve. If y'all have a water saver/conventional diaphragm assembly installed in a depression consumption fixture, cheque the characterization or markings on the valve to learn what the right flush volume is, and so install the parts that match that book. Also, you may have a cupboard diaphragm assembly installed on a urinal. To resolve this issue, supercede it with a urinal diaphragm associates with a flush volume that matches your valve.Read our Diaphragm Kit Guide or Control Stop Guide for additional guidance.

6) Insufficient Affluent

There may exist times when there is an insufficient book of water to adequately siphon the fixture. The start thing to practice is brand sure that the control finish is open wide enough. Another cause could be that yous have a urinal parts kit installed in a cupboard valve. In that case, but install the proper parts kit.

You may also have a depression-consumption valve installed on a non-low consumption fixture. Again, only install the proper Sloan repair parts to correct the problem.

If you have a water saver kit installed in an old, not-water saving bowl, that could crusade insufficient water volume also.

Finally, there may be inadequate volume or pressure at the water supply. If no gauges are available to properly measure the supply pressure or volume of water at the valve, then completely remove the entire diaphragm assembly and open the control end to let water to laissez passer through the empty valve. If the supply is adequate to supply the fixture in this manner, then the restriction band (A-164 on plastic guides) should be removed from the lesser of the guide to provide additional flow. If boosted flow is still required, the refill head (A-170) may be replaced with a brass low menstruation refill head (A-85). Should none of these steps prove satisfactory, then steps should exist taken to increase the pressure level and/or supply.

7) Inconsistent Flush

When flush elapsing is randomly long or short, then normal over again, then there could be pressure level fluctuation within the facility. The solution to this is checking the plumbing system pressure and menstruum capacity and adjusting accordingly.

viii) Noise at Close-Off

For diaphragm type flushometers:If you're hearing a chattering racket inside the valve during a flush, there are several possible parts that could exist damaged: therelief valve,  the inside comprehend or the diaphragm associates. Proceed to check each one until the problem is institute, and and so replace the parts appropriately.

For piston type flushometers: If you're hearing a 'thump' or 'bang' upon valve shut off then there are iii possible causes and solutions:

Cause: High catamenia pressure

Solution: Adapt command stop to decrease flow pressure.

Subtract plumbing organisation menstruum force per unit area

Cause: Piston lip seal degraded

Solution: Secure piping properly and/or cheque hammer arrestors

9) Leaking Water

In that location are a variety of places that a flushometer can leak from. Listed below are all of the possible leaky flushometer causes and solutions, listed by the part of the flushometer the leak is coming from.

Handle Leak
For diaphragm type flushometers:If you see water leaking around the handle, the handle seal or handle associates is worn or damaged. If the seal is worn, a handle repair kit will solve the problem. If the handle assembly itself is damaged in some way, you will need to replace the entire assembly.

Tailpiece Leak
For leakings occurring at the tailpiece next to the control stop, the cause could exist a worn or degraded O-ring. Fixing this leak means replacing the H553 O-ring .

Vacuum Breaker Leak
For leakings occurring at the vacuum breaker, the cause tin can exist from two things, depending on the leak location, although the solution is the same for both: Clean the vacuum breaker tube and supervene upon the vacuum breaker sack with V551A or V651A loftier backpressure vacuum breaker repair kit. If the dripping comes from above the vacuum billow during or afterwards a affluent, then the vacuum billow sack is damaged from over-tightening the vacuum billow coupling. If information technology's leaking from below the vacuum breaker, it'due south due to the vacuum breaker sack becoming worn or degraded over time.

Control Stop Leak
A leak coming from the command stop adjustment spiral (where it says Sloan Valve around the screw) is acquired by an O-ring inside of the control stop being worn. The solution to this problem is the H541ASD command finish repair kit. (Apply the H543ASD control stop repair kit for older units.)

Spud Flange Coupling Leak
A leak from the spud flange coupling (this is where the flushometer meets the fixture) tin be acquired past two scenarios: either the spud coupling has loosened and it needs to exist tightened, or the spud flange coupling gaskets have get worn and demand the following replacement parts: A replacement F3 friction ring and either a VBF5 gasket (ane-¼" or ane-½") or a F5 gasket (¾" or 1").

Flushometer Cover Leak
If you lot run into water leaking from threads below the flushometer comprehend, there are four possible causes and solutions:

Cause: Cover not tight enough
Solution: Plow off water and tighten cover

Crusade: Worn cover gasket (Gem)
Solution: Replace comprehend gasket ( Yard-106 )Cause: Cracked inside cover (Crown)
Solution:  Replace within cover (CR-124-A - Phone call to club)

Cause: Worn cover gasket (Naval)
Solution: Supersede embrace gasket (CN-76/CN-105 - Call to guild)
