“Every once in a while I would notice my hot water not being as hot. Turned out to be the mixing valve. If you know how to solder, it’s easy to replace. The valve seems durable, although I found the price ($70) high. Other than that, I’m satisfied. P.S. Start with cold water the first time—mine was hotter than expected!”
“This is no different from Plumbing Supply valves. Just make sure to clean the copper pipe/valve and use flux—it will solder fine. The other guy should learn soldering or use solderless parts.”
“I was hoping that this would be a drop-in replacement for a very old TACO valve that looks similar, and it works! It's handling my off-boiler hot water just fine.”
“The hot water line on my oil burner was leaking and corroded. I took pictures of it and went to my local Plumbing Supply. Gary in the plumbing depart told me exactly what it, a Tempering Valve, and what I would need to fix it. Unfortunately the Lower Paxton store did not have the tempering valve but he informed me the Harrisburg store on Derry Street did have them. I purchased all I needed and made the repair. 1 and a half hours later no leak, no corrosion, and the valve allows me to set my hot temperature perfectly. Thanks to all!!”
