Low pressure

[burt]

I'm new to beadwork and the forum. But learning alot.

I've noticed that when I connect my extension hose to my propane take (it's outside and coming in though the wall) and turn on my HotHead torch...I'm getting pressure enough to light up but then it gradually diminishs to nothing.

The tank is full...

Could it be debris in the hose...gunk as it was refered to in other posts?

A defective hose? Torch?

Any thoughts would be most appreciated.

Thanks

How long is the hose? How long have you been using it?

I've had the hose about 6 months...it's been used 10 - 12 times for a couple of hours each time.

It's 12 feet long. I got it from Sundance Glass to use with the tanks so I wouldn't have to go through so many of the small propane canisters.

Ok. Is it "T" grade hose? If it's not (and the rating is ALWAYS printed on the hose itself), this could be part of the problem. Propane gas will attack the rubber on hoses that are not rated "T" grade.

Now, have you tried totally disconnecting your hose from both ends and hanging it up so the ends are free to drain any accumulated "gunk" in the lines?

Also, depending on the design of the HotHead you have (there are at least 3 I think), you may have a partially clogged spud in the torch head. This can be cleaned, but you will have to contact the manufacturer of the torch for instructions - I'd order a spare spud to have on hand just in case.

One of the things that I've personally seen is that people leave the hose coiled on the floor. This can cause a siphon effect and draw out liquid odorant (which is the "gunk"). If the hose is coiled on the floor, essentially below the top level of the tank, this can happen. What I would suggest is that the hose be strung above the top level of the tank where ever possible to keep any liquid from pooling in the line. If the line coming out of the torch is above and at an angle to the tank, any liquid that is drawn out of the tank or condenses in the line will flow back into the tank.
