The product arrived early and in good condition! I replaced the current pressure vacuum breaker with the same brand and it couple to the old connection perfectly. The product is well built and should last us for another ten years. I installed the valve to be disconnected in the winter so it won't have a chance of freezing. The price is much better on Amazon,

My irrigations system originally had this valve in it. A hard freeze broke the valve. The replacement was fairly easy and fit perfectly in the place of the old valve. Shipping was fast and accurate. The valve works perfectly. Unfortunately, I need to pay a plumber to test the valve per my city's regulations.

It was hard to know what size i should get after my PVB broke this winter. they get so expensive after 1" . This one was the perfect one i needed for my back yard. I used my skill saw to cut the PVC to loose my broken one, Teflon tape around the PVC to Brass threads. use a good amount. and then just some 1" Pvc parts and connecters with some pvc glue to put it back together and it works no leaks. be sure to read the instructions on how to first turn it on or it will seem like its totally broken and leaking. i had to free some pvc shards that went down the line and blocked a few sprinkler heads but that was also easy

I needed to add a PVB to my irrigation system when I redesigned to use an underground manifold system from the above-ground zone indexing system the builder installed. I was familiar with the Zurn name from their PEX fittings, so I gave this one a try. Holy crap, this thing is sturdy!! It really seems like a product for commercial installations. I've had it installed for a few weeks and it's working great. Time will tell how well the internals hold up, but it's definitely a well-made product.

Easy to install. Looks like quality product. The only problem I have is when it came in the box, the valves and drain spigots were not aligned and needed re-tightening. But none of the leaked.
Shut off valves are very tight and are hard to turn.

I was uneasy with the "used" item description but was pleasantly surprised to see a brand new item in a torn up mfg box arrive. Excellent deal! I Highly recommend Amazon filled "used" items now.

Works just fine, my second one due to a hard freeze. Easy to install.

The cost to have this professionally replaced was well over 250 dollars. 67 bucks, plus 3 dollars worth of PVC and a can of contact cement and primer. All in, 80 bucks.
