Leaking Valve

[dale farley]

Greg,

It is definitely a drain valve, and yes, it looks like it is in excellent condition. I am sure the strainer is there to keep junk out of the valve. The valve connects to a short line that drains under the bus.

I disassembled the vavle again today and thought I had it fixed, but it is still leaking one drop every 20 seconds. That is about half what it was to start with.

I think the problem is where the plunger attaches to the diaphragm. It appears there is a rubber seal on the end of the plunger that seats against a metal flange on the diaphragm. There is an indentation where it has been seated. I either have to rebuild the unit or replace it.

The first picture shows the plunger attached to the diaphragm.

The second shows the plunger, removed and turned upside down.

The third shows the circle on the rubber on the end of the plunger. It is almost impossible to get the plunger to go back to this same circle when installing it. Of course, if it did go back, it would probably leak anyway. Because everything else looks fine, I think the rubber seal is the source of the leak.

Dale, that sure looks like the problem to me.

Can you pry out that center piece and turn it over?

It may be symmetrical and held in by friction or....

If the other side looks like new your home free.

Dale does the hole in the center go all the way thru? I assume that this valve works as Normally close, if so could you strech the springs to put a little more pressure on the diaphram when it is closed?

Jim,

I turned the rubber seal around. It was beveled on the other side, so I am not sure if it will give a completely flat surface for the plunger to mate with. If it strikes right in the center, it will be okay. I am going to install it again tomorrow and see what happens.

I am also ordering a repair kit, so if this doesn't work, I'll have it. If this does work, I'll have the kit as a backup. I have at least 4 of these valves.

Dale,

What source are you ordering the kit from?

I need a couple of kits.

Hector,

Hopefully, I will finalize something today, and I will post the source. There are not that many sources that I see on line, and I have not found it locally.

Still has not been made clear to me but it appears that you are talking about an internal leak, the valve drips water after closed rather than leaking on the floor near the valve. I also see that the piston in the solenoid appears to have a wear mark so perhaps, just perhaps the diaphragm is not being fully "pushed down". Fill the wear hole with contact cement or rubber cement...popsicle stick will work nicely and try it again....don't forget to be very neat about this operation

I got a troubleshooting guide from Goyen and a parts identification guide.
