Purchased the Watts 1" DCVA (007M1-QT) to replace one that was 10+ years old and had issues. Supply House had the best price and the new DCVA is installed and working flawlessly. I'm pleased with the product - it seems well built and I expect it to last many years. I'm also very impressed with Supply House - great price, quick shipping, very professional. I will look to them for future plumbing needs.

We hired a plumber to do the install, but it was a big savings to be able to purchase the product directly.
Great purchase.

I am very happy with the double check valve unit. Even happier to buy it from a company like Supply House. I had originally received a unit that had a leak. Called Supply House about getting a replacement part and they got it here fast. They paid for the return shipping and honestly I couldn't be a happier customer. I have purchased many things from Supply House and have never had any problems that couldn't be handled quickly and easily. Keep it up guys!
FAst delivery, Fits the need

I plan on using this double check valve on a water powered sump pump backup system. Does the insertion of this valve reduce the water pressure? Since the performance depends on the water pressure, I am concerned about reducing the pressure.
