GUEST PPSV501222WP Push Fit Elbow Shut Off Review

If you've had leaks on push-fit fittings but have used cheaper brands, that's a problem. As long as you square the tube and insert it all the way, JG fittings will not leak. This valve has a copper reinforcement ring at the bottom. You can't see it on the Revain image, but you can see it if you look at the NPT inlet. The valve that came with my tank didn't have that.

Most systems use 1/4" hose and a 1/4" threaded connection on the tank. This product has a 1/4 NPTF port which is a threaded part. The push-in fitting is designed for large 3/8" hose. If you have a SMALL 1/4…

I bought this item a few weeks ago because I wanted to replace my broken reverse osmosis tank and wanted a completely new installation. According to the company (John Guest USA), this item is a 3/8" x 1/4" angle check valve. Since most if not all reverse osmosis systems have a 3/8" male thread on the tank and 1/4" tubing to/from the tank, this was a necessary item. However, when I received the item in the mail, I immediately noticed that something was wrong. The plumbing hole was much larger…
