Cheap Replacement Backflow

Post by SCGrassMan »

This is for a church with less than zero budget. I always use the Zurn 975 XL for myself and for paying customers.

This thing has turned into a geyser. I just want to replace it with something “good enough”. I saw some anti siphon, and vacuum breakers, etc.

What is the least minimum GOOD option for them?

Depending on your store, Home Depot usually has 3/4” and 1” for under $100 that will work just fine. https://www.homedepot.com/s/pressure%25 ... ker?NCNI-5

If you can wait a couple days Amazon sells the same at cheaper prices depending on size.

Another solution would be replacing the guts. Normally the plastic check (vent) inside breaks and causes water leakage. If the brass casting cracked then better off replacing.

The sides of the pipe split in two places lol. It’s in rough shape. I’ll go the Amazon route.

Thanks!
