New member here. This might be the coolest subject for a forum I've seen in awhile (that probably sounds like robot spam). On to business... I have been scr*wed by a succession of people over our home's improperly plumbed hot water. It takes forever to get hot water to the faucets. I bought a product to fix that. It uses a valve plumbed into the water heater outgoing line to detect movement of hot water, and it then switches on a recirculating pump to push water around the circuit (so turn water on/off, wait a minute, poof, hot water is there). The pump shuts off after 2 minutes. Of course, the electronics soon failed. The company owner is a nightmare, so I am on my own. The valve mentioned above has two low voltage wires that complete a circuit when the hot water moves. I want to replicate what the product did, by taking those two wires and connecting them to.... something... that will switch power to the pump on (it's 110v) when the circuit is complete, and keep it on for 2 minutes. Thanks in advance for any ideas!
