Who uses what?

@ August 16, 2014 5:49 PM in Gas Piping - teflon tape

Who uses what and why for gas pipe sealant

I use black Permatex because that is what I was taught with and I've never had a problem with it (except getting on my hands).

Not to offend

@ August 16, 2014 9:28 AM in Gas Piping - teflon tape

I didn't mean to offend, I was just stating that there is no ONE product for everyone. I grew up with Permatex Black and that's what I still use. I won't say that I've never had a leak, but any leak that I've had has never been because of the pipe joint compound.  (it is messy and smelly, my wife won't touch me until it is off my hands, sometimes it takes days :)


Must Be?

@ August 16, 2014 7:58 AM in Gas Piping - teflon tape

I saw nothing in the code that you posted that said it MUST be Pro-Dope, are you an Oatey/Hercules rep?. It simply says that it can't be LP soluble or lamp wick (which bothers me a little because I use lamp wick all the time) :) .

I actually just looked up Pro-Dope (I don't use it). I love the description:
  • Oil-based thread sealant.
  • Not for use on plastic pipe or fittings.
  • Gray color.
  • Non-setting formula; will not harden, crack or become brittle.
  • Accepted for use on FlowGuard Gold® pipe and fittings
  • If it's not for use on plastic, how come it can be used on CPVC?

Why do you plan on removing the radiant heat? If your child has allergies the best thing to do is to not swirl up dust into the air. If you live with radiant heat now, you probably will not be happy with forced air. If you want to add A/C you could use mini-spits and save a ton of $$ verses adding ductwork ect...


Not shure

@ August 16, 2014 3:43 AM in Gas Piping - teflon tape

I'm in Virginia and have never had an inspector stipulate what I use to seal the joints. As long as it passes a pressure test it should be OK. With the quality of pipe and fitting manufacturing these days I prefer to use both tape and dope to fill the voids.



@ August 15, 2014 4:33 PM in One riser or two?

At least you can recoup some of the expense from the scrap copper. Does that thing even work?


@ August 15, 2014 5:40 AM in thread sealant

If done correctly there is no problem with mating copper to CI baseboard with Teflon or paste, as long as there is room for linear expansion. At least I've never had a problem.

And if you don't use Teflon or paste how are you going to seal the joint?

Your in luck

@ August 15, 2014 4:59 AM in Columbia Boiler Conversion Question - Baltimore

MichaelG, You will be well served by conversing with Steamhead AKA Frank Wilsey (and not to leave out his partner Gordon Schweizer). If you go to the steam section of this site you can see photos of their work and note how highly they are regarded in the industry.

Good luck,

Nothing wrong

@ August 10, 2014 9:16 AM in Flush Valve

There is nothing wrong with what I'm trying to do. I'm trying to either find an entire unit with a manual valve (they were used forever before the flushometer came out) or adapt to the existing Sloan stop and tailpiece (with vacuum breaker). Any ideas?



@ August 10, 2014 8:05 AM in Flush Valve

Still trying to figure out how to connect a manual valve to a urinal. Any ideas?


We Got Steam Heat

@ August 8, 2014 12:19 PM in kicking the city steam habit

In addition to what NBC said you should check out the shop section at the top of the page. The "We Got Steam Heat" book is an excellent resource for a homeowner who is new to the steam world. It is fun and greatly informative. Once you are done absorbing it you can re-sell it to your neighbors who are in the same predicament as you :)


Gas meter

@ August 6, 2014 4:29 PM in Burner Conversion Question - Weil-McLain P-SG0-3

Two reasons, access and liability.


@ August 6, 2014 3:34 PM in How would you....? (daycare mixing)

I would use both 1017 at the source and 1070 mixing valves on the fixtures. If the owners want to turn up the temp on certain fixtures that is their responsibility. You need to cover your butt in this litigious society we live in. Explain to the owners that the added expense is covering their butt as well.

Off topic

@ August 6, 2014 1:01 PM in Brazing without nitrogen?!

Somehow this thread got off topic, however, since we are now talking about double / inverted flares, if I have to use a CCST product for gas I use TracPipe as the fitting creates a double flare when tightened. It also dosn't require additional bonding per the manufacturers instructions.


I may be wrong

@ August 3, 2014 7:39 PM in Condensing cast iron?

I may be wrong but I seem to remember something about siliconized cast iron being used and that helps with the corrosion issues? Once again, I may be wrong but it seems to ring a bell in my noggin. I don't see anything in the product literature though.



@ August 3, 2014 5:02 PM in Survey

How do you do your estimates / quotes for system replacements?

Do you itemize the materials?

Do you do a detailed heat-loss and provide it to the Customer?

Do you do a rough estimate on the heat-loss and do the detailed one when the contract is signed?

Do you give the estimate on the first visit or do you mail / e-mail it later and if later what is your turnaround time?

Do you give options such as cast iron, mod-con, zoning?

Do you base your estimates on the type of car in the driveway?

Do you do your estimates based on what the customer wants or what YOU think they need?

How much time do spend typically on an estimate for a typical 3000sft two zone home (replacement)?

I am just wondering how others do it



@ August 3, 2014 4:34 PM in Trouble Reconnecting a Water Softener

Petroleum based products are not to be used with rubber. They will make the o-ring swell and deteriorate.



@ August 3, 2014 3:47 PM in Trouble Reconnecting a Water Softener

Use some good silicone faucet grease on the o-ring and push the fitting straight down. Don't have it cocked like it is in the picture. If you do not have access to faucet grease you can just use a liquid dish soap.



@ August 2, 2014 2:18 PM in Condensing cast iron?

I remember the rAY thread from a few years ago, but has anything come from the CI condensing technology? I can't find anything on the web about the rAY since 2011. It's not on Mestek's website.

How have the KN's been holding up?

Condensing cast iron?

@ August 2, 2014 10:31 AM in Condensing cast iron?

How does the Hydrotherm KN series boiler manage to provide high efficiency coupled with cast iron? Granted, it is a manufacturers claim, but up to 99%efficient? Is it a disposable unit, glean the efficiency while it rots out?

I would love a high efficiency cast iron residential unit. How do they do it?



@ August 1, 2014 4:04 PM in Flush Valve

That is what I am looking for. Now my only problem is figuring out out if there is any way to connect it to a Sloan stop and a 3/4" tailpiece. If not, is there any type of 3/4" tamper-proof angle stop? How do I connect to a 3/4" tailpiece / spud?
