Wep Water Over Flow in Hot Water Tank

[washregal]

I am having issues with .. When my weep's come on the Hot water Tank over flows.

No issues when they are off. Does anyone have any suggestions for me on this?

a check valve needs to be repaired/replaced.

would adding one check valve to the bottom of the water tank where the weep comes out solve the problem?

If you mean the bottom of the rinse tank, probably not. I doubt that the backpressure would be anywhere near sufficient to make the valve "check". I had to put one on each bay.

It might compound the problem. There's a reason why it's happening, either an existing check valve at the pump has failed or the pump itself needs servicing. Try and find which pump is allowing weep back to the tank. It's pretty simple - run all the bays until the plumbing to the pumps is hot, turn them all off and turn on the weep. Whichever is weeping back will have the plumbing get cold. Then you can look for the cause.

To find the bad check valve: turn on your weeper system. mark a spot above the water line in your tank. you should be able to see the water rise in the tank. Close all your isolation valves (1 per pump) that are between your tank and the check valves. Water stops rising. When you open the right one w/bad ck valve the water will start rising again. Don't loose sight that you could have multiple ck valves leaking by.

Sometimes you can even hear the water flow backing into the tank. When you CLOSE the isolation valve the sound will cease. Then you can double verify by above method.
I just found two leakers in my system this week.

I've had a similiar problem but when I turned off my drip the tank still overflowed. I relaced the hydrominder but it's still doing it.
So I thought it must be one of the check valves to the bays.
Would the failing check valve have a magnetic charge?
My question is how do you find out which one?

Look at the outlets on your hot water feed tank. A common way to feed each pump from this tank is tank outlet / ball valve / check valve / feed to pump. If this matches your setup, a defective in-line check valve in the feed line could be allowing weep water to backfeed into the tank thru the pump.

Check valves have no "charge." Do you have hot water in your tank? Do you have hot water on soap and cold on rinse? Use the method I described above except run each bay on soap, allow the plumbing to the pump to get hot, then switch it to rinse. If there's a bad check valve the line back to the tank will get cold.

Sorry I was thinking of the solenoid.
The only problem I have is that a couple of the bays have hot water rinse.
