Steam Pro Questions

ksd99

Living in SW Michigan, having problems finding a steam pro. I’ve had 2 people out and they contradicted themselves - I knew they were knuckleheads. I am thinking about interviewing them before they come out - what kind of questions could I ask them that would prove them to be proses? My boiler is working but I have knocking 9some hammering), some dirt in the glass water level and concerned the pigtail could be getting clogged.

There are two questions to ask: what are the most likely causes of the hammering (pipes sagging or with not enough pitch) and what pressure should the boiler cut out at (1.7 psi for most systems). Those two should separate most of the goats from the sheep...

Actually, if you are at all handy, you can probably have a pretty good go at it all by yourself. Cleaning the pigtail is easy -- turn off the power and let things cool a bit, disconnect the wires to the pressuretrol (note where they were connected!), take the pressuretrol off, try running some water into the pigtail. It should flow freely. If not you can take it off the boiler and try again -- or just get a new brass one. Reinstall everything (use pipe dope or some Teflon tape), hook up the wires, and off you go. Check the pressure settings on the pressuretrol -- as I say, 1.7 psi cutout, .7 psi cutin should work for starters.

The hammering may be a bit harder to track down, but check all the near horizontal pipes for adequate pitch to drain the condensate -- not just end to end, but check for sags. Check radiators that they slope towards whichever end is the drain -- they don't have to slope much, but a bit.

Thank you for responding. Where does a person get a new brass pigtail?

or a local plumbing / heating supply shop, they are pretty common items.

I agree with Jamie. You can probably get your system pretty good with help from the fine people on this forum. And welcome from a 30 year SW Michigan ex-pat.

in this day and age of everyone carrying their cameraphones, it should be easy to ask for and receive some photos of previous installs.. i think that's as good a way as any to gauge their level of care and craftsmanship

I am going to try it once the temperature goes up outside. Also I have a 30psi which the needle never moves because I have pressuretrol set at 1.5. Could add a lower number gauge?

Yes you sure can. 0-3psi is common. Do some searching on this site and you will find lots of threads of people doing just that!

Yes -- it's easy. Take that pigtail... and at the end where the pressuretrol is mounted, add a T with the crossbar going left and right. Add short nipples on each end. Add a 90 degree elbow and another short nipple going up on each of the nipples, and mount the gauge on one of them and the pressuretrol on the other.

Won't always work. Us brick-phone users are still out there. ;P
