I would not expect success attempting to glue or seal that. Apart from the general difficulty of "plastic of unknown type" repair, it's usually the case that when a plastic item cracks one place, other places are likely to follow, even if you could get this crack sealed successfully. They do not age gracefully.

The catalog and product sheet don't mention backflow, and I assume that's a feature they would want to highlight. The same company also sells backflow prevention devices so its something they know about. You could call and ask, or test it by trying to make it backflow, but let's assume that it doesn't protect against that for the rest of the answer. A ...

Certainly The NJ Plumbing Code (based on the IAPMO UPC) expressly permits the use of RPZs for protecting irrigation systems in 10.5.10, and I cannot find language in the code that'd prohibit the use of a single backflow preventer to feed multiple potential contamination sources. Note that with your proposed configuration, it's possible for irrigation ...

In my area, it is common for PVB to break if incorrectly winterized, but local water code requires these to be installed and inspected annually, with an inspection report filed with the city water authority. I see duct tape on the PVB so this is likely cracked and causing the leak you mentioned in a comment. I'd hazard a guess that water does come from the ...

One way to accomplish this is; You can add one Inline spring check valve to each supply line. After the check valves you can tee the hot and cold together with one 1/2" copper pipe out into a 1/4 turn valve and then to the correct threaded piece to accept the washer supply hose. The check valves will prevent water from one pipe from pushing into the ...

The black sprinkler pipe is probably HDPE and not PVC so you need a different connection method than with PVC. Your best bet is to check with a local sprinkler supply company that can give you the right option for local requirements. Around here they use hose barbs and hose clamps but other places may require different connectors when transitioning from ...

The ONLY way to ensure that there is no water trapped in low spots in a sprinkler system is to BLOW it out with compressed air. Until that is done, there is almost certainly some amount of water trapped and it only takes a small amount to split the buried pipe when it freezes. Generally sprinkler pipes are buried only a few inches deep and even in moderate ...

That's just a basic quarter-turn ball valve that's been tossed in there for shutoff purposes The cracked part isn't part of the backflow preventer proper; it's simply a quarter-turn ball valve that's been put there to allow the preventer to be shut off as part of winterization or testing procedures. Simply replace it, preferably with a version that has a ...

If these appliances are supposed to drain into a standpipe, then they need to be connected in a way that allows them to drain in open air. Get a double wye, of the appropriate size to fit on the standpipe. Then put one drain into the left wye, the other into the right wye, and leave the center wye open. If the standpipe opening is large enough to ...

The only way that could happen is if the nut was loose and then pressurized. Those BFPs are serviceable and the nut must have been left loose. If you can find the components from under the bell you can probably reuse them. Otherwise a replacement kit can be purchased. Before reusing anything make sure the threads were not stripped, possibly from over ...

The size and configuration of the entire piping system that supplies your irrigation setup, from point of entry to your property (usually the water meter) all the way to each sprinkler head, along with pressure, determines how much water is available. Pressure is just one piece of the puzzle. If there is a regulator on your system it would typically be found ...
