Bob Valve driving me nuts

[copperglobe]

Hello, I use a Bob (Robert) Valve to fill my hot-water feed tanks for the self serve pumps. For the past few months the float in that tank begins to bounce when the tank is almost full. Replaced the valve with a new one with no luck. The pumps have nothing to do with it as I've experimented simply draining the tank and watching it fill back up- again the bouncing. Any experience with this? 23 years in the business and it's got me stumped!

My two stage valves tend to bounce. I think it is because the water enters with such force that it actually causes the float to bounce and the valve fluctuates between stage 1 and 2 and bounces.

I do not understand how a Bob valve could bounce unless the float is actually bouncing on the water.

The float is bouncing in the water. I have no idea why either

Maybe change the angle of the water entering the tank from the valve or just hang something from the valve opening to make the water drop without splashing as much?

Another option would be what my predecessor did for the 2 stage valves. He put a pvc pipe on the outlet so that the water entered the tank under the water level. Since the outlet was 1", the pipe was just a piece of 1" pvc that went into the water with holes drilled in it to allow the water to escape without being forced all the way to the bottom. Just a suggestion.

That's what I do. It helps.

Turn the valve so the outlet is a bit past vertical.

thats what I do too, specifically to stop the float bouncing. It also reduces air bubbles in the water, which are not good for your pumps.
