Plumbing ? Which Electric Water Pump Will Work?
Posted on | December 16, 2009 | 1 Comment
I purchased a propane tankless hot water heater for our cabin. I want to use an above ground cistern for my water source, however when I read the instructions, I found out that the unit has an inlet valve that requires a minimum of 30 psi to operate. I am looking for a small 110v centrifugal pump to create the required pressure, but I don’t know which one will get it done. Most of the pumps are rated in GPH and not psi. My water inlet is 1/2″. Can I use a submersible or will I need a remote unit – say 1/2 hp, 1″ output @ 330 GPH and use it to create more pressure when I reduce it to 1/2″?

I’ve tried to do this with regular pumps, and the slight pressure the water already has is going to cause problems. Unless you wanted to install a submersible pump in your cistern and pump from there, I think a pressure boosting pump would be best, like this one: http://www.pressurebooster.com/
There’s quite a few other brands of these, you might want to check all of googles results for more information:http://www.google.com/search?hl=en&q=wat…
