Water overflow in Rinse Tanks - Perhaps City Water Pressure?

[washregal]

I have two Hudson valves in my water tanks - these are great valves - story for another time.. I highly recommend them for HP water shut off valves....

Take a look at the picture attached - I have had overflow on these tanks to varying degrees - I cant for the life of me figure out what the issue might be - I have isolated my weep valves - and still at times I come into the equipment room with these tanks overflowing.. Seems to happen on colder damp days - not warmer days where users arent washing.. Has anyone experienced this? The only thing I can think of is perhaps excessive water pressure from the city?View attachment 1139

Have you made sure the check valves on the outlets are ok?

Have you confirmed the valves aren't leaking by and overflowing the tank?

Excess city pressure shouldn't cause them to overflow. It will cause them to not open.

Replace the valves. We had nothing but problems with the Hudson valves. We got rid of them years ago, junk!!

I have specialty equipment so when they went under I have not been able to find a valve that would fit my tank except these. I was having the same problem and found that they will leak around the threads at the top of the valve. I just taped them good and it stopped the leak. They come in the box not very tight at this fitting. Other than that I've no problems out of them.

Cebo,

My Specialty's have common 24VAC valves on the outside part of the inlet & have similar float valves with an arm ... like old style toilet tanks have on the inside of their tank. As the float arm rises the simple arm controlled float ball causes the small 3/8" valve to shut besides the Dole shut off. Size wise they look about the same as ours based on your pics. I don't like the fact that if the Dole solenoid fails the tank could go dry though ... pretty rare though.

They are washing machine valves. Hot and cold intake that goes into the small tank. I bypassed this and do just cold only. The overflow on the Hudson's came from them leaking around the threads. I was never able to find a float valve like specialty had after the went out of business.

I've put Walters 1/2" valves in the small Specialty tanks. You just have to bend the float rod into an S-shape so it will fit. It works in the plastic tanks just as well, just use two 1/2" couplings with a 1/2" nipple between them, then a 1/2" barb on the end, and the brass pieces fit perfectly where the old valve went.

Update on this - I spoke with hudson and they re-designed their top cap to include a gasket and a lip seal type design.. So far in for about 3 months and working very well.. I am very particular about water leaking on these tanks as my sewer costs are outrageous. I do believe in the design / engineering of the Hudson's - They hold up very well in hot and cold water... Now that I believe Hudson fixed the leak issue - I have to say "No Brainer" on these valves for HP water applications.. If you have these contact Hudson directly on the new cap part number and cost.The ease of repair / functionality of this product and above all else low cost makes this the perfect solution..
