Black bleed screw is indeed epoxy'd, metal tube isn't epoxied and my blow gun is connected, fully sealed just backwards, if that's a problem I could change it but it'd be a big hassle.

I can't recall if blowguns can seal backwards but they're supposed to be used the other way round. When pressurizing the chamber, can you tell if the blowgun seals or does the sprinkler valve leak too much?

If it helps, my blowgun seals backwards.

I'm pretty sure the blowgun is sealed, the only place I can hear a leak is at the output of the sprinkler so hey.

Electrical tape over the rectangular slit that leads to the tiny pipe in the chamber.
Wait, all you did was use electrical tape to seal the hole? If so, go and buy some damn epoxy.

For MrCrowley
I thought that was referring to the hole in which he epoxied his blowgun. It was in response to this question:
Also, make sure that there is no leakage around the area that you installed the blow gun. On my gun there was leakage there, and I had the same problem as you.
The blowgun hole is sealed shut with a lot of epoxy, the whole area
He asked if he should epoxy the rectangular hole and I'm not sure if anyone answered him.

Dewey, I think his valve is slightly different in that it doesn't have both a rectangular hole and circular hole. I can't really tell what the rectangular hole is for as I've never used one of these valves before but I doubt there's much harm in epoxying it. One can always drill the epoxy back out if there is.

Yeah, Crowley is right, my valve doesn't have the circular opening, there was electrical tape over the rectangular one as a test to see if it would help rather than the more permanent epoxy option.

I highly doubt electrical tape could seal a hole in that fashion at even low pressure. If the pressure is on the pilot side, it will just push around the tape and leak out the sides. If you use epoxy, and it turns out the hole shouldn't have been blocked, you can just drill a hole through the epoxy and no harm is done!

Okay, I'll do that now. It's half 12 in the morning so I wont be able to test anything for a good 10 hours unfortunately.
