Zurn Wilkins 1-375XL 1" 375XL Reduced Pressure Principle Backflow Preventer

I like well built.I haven't installed yet but it will be good one.Can't find were to install air blow out connection for splinkler system.

Just got this today and installed it very quickly.Is working like a charm. Very excited to have one that I can "snap out" for the winter w/o the threat of freezing and blowing out a $250 part like before with the Wilkins 975XL, every year...no matter how well you drained it.I did have to run to Home Depot and buy a 1" nipple and 1" coupler in order to attach to the existing male threads on both pipes coming out of the ground on both sides of it. There is no other way to easily screw in both ends in different directions at the same time. The coupler takes care of that. However it is 2 female ends, so you need the 1" nipple.If you are replacing your 975XL with this one, the added 1" coupler and 1" nipple are perfect to make up the about 2" of space that will be there because the 375xl is slightly shorter (when attached).Install was a breeze. Just used a good double to triple wrap of white plumbing tape on all male threads. Pipe wrench. Done.For some reason, the box (at least mine) does not come with any installation instructions. I wanted to be sure i pressurized it and set it up right on the first try.I found this online install doc helpful.http://backflow-supply.com/backflowcd/pdffiles/Wilkins/Reduced%20Pressure/IS375-114-2.pdf

Replaced my old system. My wonderful neighbor. Had it up and running in about an hour. Works great

had to make a few things work, but the product was better than I expected (so far anyway)

I've had two destroyed or stolen for the copper. This one has no copper, and has been left alone.

This is an extremely easy unit to adjust and maintain.

If you are replacing your old one, this one is good. If you never had a Zurn backflow preventer before, it's way better than most others, especially since you can take out the entire guts of this thing and put it inside your house during the winter so it does not get damaged from freezing. It also comes apart by removing only 4 bolts so that you can screw the ball valves onto your existing fittings without tearing out your pipes.

Great product and saved a decent amount of money. Thankful for private sellers! Our grass thanks you too!
