Thermostatic water tempering valve will keep the cold water at 70F. summer and winter. Now the fun job, moving all the washers back in and hooking them up. More pics to come soon.
Jeff, isn't there some way to have the hot water in a recirculating system loop? It looks that hot water will never get to the machine at the end of the line.
The thermostatic valve came from a darkroom supply company, used for film processing. See link below. It's a bit pricey, I found some cheaper ones, but they had a low limit around 95F, that was a bit too high.
Yes the drain line has a proper trap at the end of the line, it got cut off in the photo.
I thought about a recirculating pump for the hot water line, but the sink is near the end of the line, so I can just run the water untill it's hot before starting a washer.
That is a very nice basement and the plumbing is very nice indeed. I'm a big fan of nicely done copper line. I wish I had that kind of space under the house. I have been adding plumbing in the kitchen with CPVC which has worked out well for over a month now. Nice work.
