That's why it's important that the Class 1 connections must fit the hose thread
utilized by the fire department.
I used the same 100 feet of hose, a hose thread
to 3/4-inch pipe thread adapter, 90 degree elbow, 10-inch pipe nipple, 3/4-inch pipe cross, 10-inch nipple, 3/4-inch plastic ball valve, 10-inch pipe nipple, 90 degree elbow, and a plastic shower head (total cost less than $10, not including the hose and Lixits).
Besides the tubing and PVC, you'll need an automatic anti-siphon valve (or a manual valve if you're not using an automatic controller); a 155-mesh filter, a 20- or 30-psi preset pressure regulator [ILLUSTRATION FOR PHOTO 3 OMITTED]; a valve box [ILLUSTRATION FOR PHOTO 5 OMITTED]; an automatic flush valve, one 3/4- by 3/4- by 3/4-inch SSS T, one 3/4- by 3/4- by 1/2-inch slip-slip-thread T, one 3/4- by 3/4-inch slip-thread 90 [degrees] elbow, one 3/4-inch male pipe thread by male hose thread
, and one 3/4-inch hose shutoff [ILLUSTRATION FOR PHOTO 6 OMITTED]; and PVC pipe glue.
Get a valve with hose thread
so you can use the garden hose to transfer water to the garden or a bucket.
Add a brass cross-over from a pipe thread to 3/4 inch [water] hose thread
and you've got grab-a-valve instant internal fire fighting capability.
32% of units surveyed had sinks or faucets with hose threads
not equipped with vacuum breakers (NSN: 4820-00-164-3377).
As you shop for one to put on the far end of your hose, remember that gate valves come with either pipe threads or hose threads
; you want hose threads
Best practice--Order NSN: 4820-00-164-3377 and install at all sink and faucets with hose threads
Recommendation: Order NSN: 4820-00-164-3377 and install at all sink and faucets with hose threads
All sink and faucets with hose threads
must be equipped with a vacuum breaker.
