I used to have a washing machine that could save the warm soapy water from one washing cycle and re-use it for the next cycle. Now I don't have that machine any more, I wonder if I can hook up a water pump and a switch: to pump all the warm soapy water out of one of the double laundry sinks & back into the washing machine. What kind of pump can I use. It doesn't have to be a sump pump, it need not have a switch; because I can hook up hose and an electrical on/off control switch to otherwise permanently on wiring/switch. I could even get a motor from something like a power drill (or a garage sale drill), and mount it all under the sink, where there is lots of room generally. I am not sure how long it would take, i.e. what kind of g.p.m. of the pump should be, the faster the better. Any suggestions where to get the component of such a water pump? I would prefer to really keep the cost down.
I only know rec.woodworking and this group, which I treat as building &/or constructing, and know of no other place to put is type of Q at the moment.
