Customer Reviews

Excellent product

I installed one of these to reduce my municipal water pressure from 120 psi to 50 psi. This regulator is extremely easy to install and I left it set at 50 psi, and I and have plenty of water pressure. This regulator seems to be very well built and I hope it lasts a long time. The price from West Side Wholesale is the best that I could find, and the order was shipped the same day.
