Misol Motorized Ball Valve 1/2"(bsp) dn15 / 12vdc / 3 Way/Electrical Valve/Ball Valve with Acuator / Cr01 / Reducet T Port

Last year we bought a 2006 Class C Outlook last year and are enjoying the heck out of it, especially in boondocking situations. Since we only carry 43 gallons of fresh water, the resource is precious. I really came to hate how much water we would waste to get hot water to the bathroom sink and shower. I'm pretty sure we would use a full gallon of water before the HW arrived at the shower head. I know some people capture this water for other purposes, but I was looking for something more elegant.To improve the situation I decided to install a re-circulation line. I could install a 12 volt switching valve to run the water for 15 seconds or so before taking a shower, which would run back into the fresh water tank.This Misol valve only has two leads coming out of it, so you need a switch that will reverse the polarity. I used a double pole, single throw switch, ON-On like this. For the +12 volt supply, I tapped into the supply for our propane detector, with an additional 2 amp inline fuse.So how well does it work? I was really pleased to find the system working properly the first time I turned it on. In the up position the valve opens and water is shunted back to the fresh water tank. In the down position, the valve operates, closing the route to the tank. It takes about three seconds for the motorized valve to operate.The only issue was the delivery time, since it comes from China. It was just what I needed and if I bought it in the USA it probably would have cost a hundred bucks.

Valves seem to operate well, the left and right ports are "Full Port" opening, the path from the bottom port to one of the side ports is smaller as described. They are listed as DIN-15 or 1/2" which is correct, although there does not seem to be any taper on the treads. Extra turns of Teflon Tape seems to solve the problem.Seller shipped quickly, and they arrived well ahead of the scheduled date. In addition, I mistakenly thought I had received only 2 valves when I ordered 3 (There turned out to be 2 valves in one box, and the bottom valve was not visible when I opened the box), I emailed the seller and got a very prompt response

Supplied direct form HK at a very good price and works fine. If I have a critiscm of it it would be that the transfer port in the right angle direction is slightly smaller in area and delivers a lower flow due to it's design.
