Incredible Service & Solid Product

Customer service is top notch, easily one of the top 5 customer service experiences. Check valve was easy to install and works great.

Quick service

I was impressed on how fast this was shipped & very happy they use USPS as a shipping option. The only thing I don't like about this vendor is the weekly if not daily sales e-mails. If I received this many from every vendor I would spend all my time reading unsolicited e-mails instead of treating potable water for my community.
