cf set-up?'s

Postby gary » Mon Jul 07, 2008 8:44 pm

-Where is the best placement of ball valve for final transfer in the cf setup?
-Are ss supply lines ok to use from barrel to pump?
-How do you prevent your 3/4 threaded fitting from comming up into the bottom of your drum and preventing complete drainage?
-After you enter the drum through your drilled hole off your inline heater tee whats the best method of attaching to cf?

Anywhere after the pump and before the CF.

Yes as long as they are rated for 200psi and 180F. Some are, some aren't.

I just threaded it in tight and it doesn't stick up inside mine. Use a fitting with a short amount of threads.

A short section of threaded pipe.

Isn't the 3/4" bung on a metal barrel NPT? NPT is a tapered thread so I don't see how a fitting could be threaded through too far.

But I know people sometimes put a standpipe in there so I must be missing something obvious.

Apologies, it is the Brass [Tonval] Skin Fittings with Hose Connection (1") I originally purchased a chrome one but the plating was flaking off.

It's not exactly NPT, but it fits. What they mean is that it might stick out into the barrel a quarter of an inch.

ss supply line?

Postby gary » Wed Jul 16, 2008 2:01 pm

The standard ss supply lines are rated for 140 f and 1450 psi and the larger 3/4 for water heaters are for 160 f and the same psi?? Could either be used to supply pump (suction) and from pump to inline heater (pressure side). Even though I will heat to 180 f there must be a margin of error in the specs??
