Having problems with water pump and I'm addressing that. Here's the question. When we follwed line to water supply which is from a fresh water tank. We also found a check valve in the line. It's after market check valve purchased from ACE hardware, sticker was still on it. Is it even needed? I'm assuming it was put in to keep water in the line so the pump wouldn't have to work so hard?
Suggestion or Ideas?
 
That could be one reason, the other reasons, to stop the head water coming back into the fresh water or maybe the fresh water pump was sucking air thru the tubing from the head.
 
It might not be needed. But if it's there, there is more than likely a reason for it. But it may just have been put there to compensate for a pump going bad that doesn't want to self prime like it should.

There is already a check valve/ball in the raw water wetter end of a Crown as I recall.

Figures, another Crown head problem. ;-)
 
My friend has that setup. You need that valve for all of the reasons mentioned!

1. Fear of germs from any back flow.
2. Pressure pump will want to draw on the head line.
3. Head pump will need to run longer to draw the water back.
 
I hope it isn't the same tank that's also used to provide showers and drinking water.

Happy cholera y'all!
 
My guess the check valve is there to help the flush pump keep it's prime, AND to prevent possible contamination of the fresh water supply from the toilet. How reliable it is, is another thing. I don't think Raritan would approve. If the check valve ever fails there's a possibility of contaminating the water supply.

However I think a vacuum breaker between the flush pump and the bowl WOULD prevent contamination; Isn't that the same approach that's used on the fresh water toilets?
