Missing o-ring: pipe fittings

As others have complained, the o-ring was missing from the package. The product is an exact replacement, shipping was great BUT I don't want a leak from reusing an old o-ring.

Pros
  • weight
Cons
  • so-so

Here's my photo for those who ask.

Exact replacement for the N35 that came before. No cutting or line changes, just RR. Raised my line pressure from 140psi to 60psi where it should be.

Pros
  • speakerphone
Cons
  • the list will be long.

Perfect replacement for Watts N35B

Perfect 1:1 replacement for Watts Series N35B pressure drop value. Replacing the old value was excruciating, but installation was a breeze. The new value works great.

Pros
  • Cool product
Cons
  • When in doubt

Only one o-ring included

This is an exact replacement for an old broken Watts regulator. However, only one O-ring is included. I need to reuse one of my old o-rings and it's leaking a bit. Emailed Watts and got an O-ring in the mail a few days later. It should have two O-rings. Many of them are only used for replacement and not for reinstallation. Two o-rings make life a lot easier, and the added cost of one o-ring can be as little as pennies.

Pros
  • Multiple competitors
Cons
  • Functionality

Should have bought it a few years ago

A reliable working water pressure valve. It was easy to install right out of the box and I didn't need any extra parts. The one I replaced played up, and after completely tearing it apart I found out why. The spring and internals were corroded to the point of failure. After installation, I proceeded to replacing the water expansion tank. When the water was back on, I adjusted the water pressure valve to 60 psi. Now everything works fine. Although the previous water pressure was set at 60psi…

Pros
  • Perfect for outdoor activities
Cons
  • Upgrade available

Works great. See included in the review.

I have a well and a pumping station. The fountain pumps water into an equivalent 200 gallon (30-50 psi) pressure tank, which pumps through a Robertson valve (quite a larger version of what's in your toilet tank) into a 1,000 gallon storage tank. The holding tank is pressurized to 1 bar (14.7 psi) and allows diffused gas to be released from the well water so that only water is pumped into the home. Which petrol? I don't know, never mind. Chlorine injection: let's sleep at night. The water from…

Pros
  • Outstanding overall performance
Cons
  • Some minor things
