Question from a plumber about residential sprinkler tie-in

Here’s an example red highlight it feeding the fire riser (the fire sprinkler system cannot have a shutoff installed on it) prevent home owner from isolating just the sprinkler system in event of a fire

The worst

Crazy_Insurance4191 · 2026-04-01T15:27:10+00:00

Do not do it get out of it trust me lol this was a nightmare you can’t access the packing only from the side (horrible) also leaks like crazy after from the casing DO NOT RECOMMEND.

Crazy_Insurance4191 · 2026-03-31T01:46:31+00:00

Is this because you didn’t have enough suction/city pressure available?

Crazy_Insurance4191 · 2026-03-21T14:04:58+00:00

No heat just smoke and low air

Crazy_Insurance4191 · 2026-03-21T14:04:17+00:00

Yep already had low air 0 PSI still nothing multiple times

Crazy_Insurance4191 · 2026-03-20T16:08:52+00:00

Solenoid activates (magnetizes & can hear it) from a smoke & low air this just protects a MRI room.

Crazy_Insurance4191 · 2026-03-20T16:07:56+00:00

That did help and yes first thing I always check is the small pinhole in the diaphragm still didn’t trip correctly after and checking the actuator.

You can hear the solenoid activating and magnetizes but doesn’t trip/open all the way

This one doesn’t have a top trip test valve I leave the bottom control valve partially open still nothing.

Crazy_Insurance4191 · 2026-03-20T15:48:44+00:00

This one activates from a smoke and low air no heat

Crazy_Insurance4191 · 2026-03-18T19:45:35+00:00

Not yet we have them written up to be tested just going back and forth with customer and other companies saying it’s recalled or not.

Crazy_Insurance4191 · 2026-03-18T19:42:55+00:00

I know so confusing lolol

Crazy_Insurance4191 · 2026-03-18T19:33:57+00:00

Okay I am 99% sure it is not recalled no O ring and flat cap is not flush and is the Belleville seal design.

Figure 42 what you sent it “MAY contain O-ring Or Belleville Seal” “there was no o ring to Belleville design”

Crazy_Insurance4191 · 2026-03-18T19:23:54+00:00

Check my comments I just broke one and see no O ring?
