The 3/4 in. 975XL Reduced Pressure Principle Backflow Preventer is used on non-potable water applications for high health hazard protection from both backsiphonage and backpressure of contaminated water into the potable water supply. The wye pattern design with short lay length eases installation in compact spaces, and the cast bronze body includes separate access to the relief valve and each check valve for reduced labor costs and repair time.

After 18 years of service, my old Zurn Wilkins backflow cracked in the cold that killed all shrubs as well. So I bought the exact replacement and my sprinkler guy installed it for me. Now, no leaks and my system works fine. Our Metro Water Service checks backflow every year in the spring. So, we have to get the backflow unit fixed or replaced if it fails their inspection. My old one was needing repairs last 3 years. Hopefully, I won't have to do it for many years. My sprinkler guy said he will remove it during winter so that I can keep it in garage all winter and then in spring he will put it back. This will improve the device's longevity.

I bought this Wilkins 1" 975XL Reduced Pressure Backflow Preventer - (bronze) , I reached local contractor/shops every one was costing a fortune. I saw the sale on amazon and was not sure to buy online, I thought of contacting the seller with my questions before placing the order, better to be safe than sorry.Wonder what as soon as I submitted my questions, I got a call back to clarify the questions that I had. Shipment was through Fedex! and reached before time than noted on Amazon. Great Price, Great customer care, Great shipment, Great product. I could rate 10 stars if available!The certified professional who installed the backflow was also amazed on the price and got the contact info from me. He said he could pass on this reduced cost to his customers.Thanks for the best business ethics and the care for the customer.**** The product review is for the company that I bought from.Wilkins 1" 975XL Reduced Pressure Backflow PreventerSold by Low Overhead Door-- apparently it is displayed under different seller under amazon so adding this info for the web users.The unit also passed ABPA*****

My water company says that it’s a county rule to have one if you have a well. I haven’t installed it yet but it looks to be well made.

I was replacing a 975XL with a 975XL and I found the new valve was about 5mm LONGER than the original. The longer length caused a mismatch at the union. The unions are bottomed out in the valve so there is no adjustment there.Other than that, the valve works well, replacing a worn out valve that couldn't be repaired with a rebuild kit.

I used this to replace a unit that had cracked and would no longer seal properly. It took all of 15 minutes to install and works perfectly.You can’t go wrong with Zurn product or this supplier. Shipped very quickly and well packaged.
