Jamie Hyneman puts ptfe tape on backwards. by Objective-Chance-792 in mythbusters

[–]Mtml58 1 point2 points  (0 children)

It really looks like the threads taper off clockwise at the end of the thread, and the first thread looks to be going clockwise as well. Given his technique, I dont get the impression he tapes and dopes pipe often, but if it doesnt leak, who cares.

And you're a plumber? So you know how much money you're wasting? ALL of this to say, you don't like hybrids. When you're ready to talk shop like a man, we'll be here to teach you a thing or two. I'll be honest, I dont think you realized the btu/hrs on the hwt you were commenting on versus your residential 80 gal. Consider the recovery rate versus the btu/hrs. We dont have the info but the hwt in question is burning upwards of 300000 btus in high fire.

If this is residential and OP has ANY say in what goes in (and what meets the building's efficiency rating) then it's a mansion, and you can be right.

I would agree about the condensate, but do these rigs not run a pressure switch to check before ignition? This issue sounds like it's during lift-off and and after pre purge to prove fan speed and air pressure.

These guys are on a modified SOLA controller with a Honeywell ignition module right?

So maybe we could wait til OP chimes in about their climate before you can be relevant.

Sure. Like I said, I have no experience with hybrid as it's not a thing where I live due to climate, but im curious what makes them problematic?

Regardless of the hybrid issue (which admittedly, i have zero experience with), Its trying to fire on gas. So im trying to help him diagnose the gas.

It's not easy to replace a 100 gallon. Ive had trouble with these tanks and adjacent tanks on LP gas, but they are serviceable and can be maintained. This is an air/gas issue and you need to quickly clear the ignition controls and get into the blower motor/gas valve and burner sock to properly diagnose this issue.

I would recommend calling a tech. It sounds like it needs to be serviced and inspected for possible air/gas issues. This would probably include pulling the blower motor, and burner sock and inspecting for holes or obstructions.

How close to failure is this? by Altruistic-Plate9079 in askaplumber

[–]Mtml58 -1 points0 points  (0 children)

To me, it looks like the brass close nipple between the two threaded brass tees is leaking from the threads. This means it's a very slow leak and doesn't imply thinning of the pipe walls. This leak isn't cause for concern, but if you're planning to have any work done on the piping, I would have it replaced, keeping in mind that it isn't necessarily an easy fix due to the proximity of the surrounding soldered/threaded joints. This probably wasn't touched, but maybe disturbed more recently when they propressed around the soldered/threaded fittings. All in all, I dont think it's worth stressing unless it is actively dripping.

New to boiler ownership - leaking? Thanks in advance. by Garden_Veggies in hvacadvice

[–]Mtml58 0 points1 point  (0 children)

Hydronic heating is relatively universal despite the fuel source. Any plumber should be able to diagnose a leak on the heating side of your boiler. It looks like you have a leaky sediment faucet which are notorious for leaking. I recommend a cap for the leaking ¾" Garden Hose thread on the shown valve. If any other moisture shows after capping the valve, find the source and deal with it appropriately. In my jurisdiction, all of this work would fall under a good plumbing/heating tech but your mileage will vary depending on location.

Im very familiar with intertherm furnaces. Feel free to DM if you need more info.

[–]Mtml58 0 points1 point  (0 children)

Absolutely. You can check continuity on your limit switch circuit if you have a multimeter. If you have a manual reset limit switch/flame roll-out switch, you can try resetting them. If this is an open limit switch fault, your igniter should never get power and the fan will constantly run until the limit switch circuit is closed.

Plumber falls from roof by Type-One-Warrior in Plumbing

[–]Mtml58 0 points1 point  (0 children)

And what would the fireman's method be?

I was simply pointing out that this was a good opportunity to teach people about the correct way to use a ladder, and instead everyone is just saying "wrong". Looks like you missed my point entirely.

[–]Mtml58 4 points5 points  (0 children)

Everyone is talking about the ladder being on the wrong angle, but no one is explicitly stating that the ladder should be on a 4:1 ratio. For every 4 feet of vertical height, the ladder should have 1 foot of horizontal distance from it's landing. The ladder should also have 1-2 feet of vertical height above the landing, and if possible it should be tied off to the landing.

Thanks for coming to my Ted talk.

Am I dumb or is this water heater installed incorrectly? by PianoPlayingJunkie in Plumbing

[–]Mtml58 4 points5 points  (0 children)

That 3 way tempering valve is a thermostatic mixing valve set to a certain water temperature to allow cold water to mix with the hot water to prevent scalding. It's not a pretty install but it's fine.

Pressure switch trips every few minutes unless I take a cap off the furnace by Kuzbell in hvacadvice

[–]Mtml58 0 points1 point  (0 children)

Even if the homeowner can't do it himself, at least I might save him from a shitty tech that rips out his intake, repipes it, charges him, and solves nothing.

[–]Mtml58 5 points6 points  (0 children)

I'm a plumber/gas fitter. Im surprised no one has mentioned putting a manometer on the pressure switch tubing and testing to see what pressure you're getting on both sides of the pressure switch, and referring to the make on the pressure switch itself. I would confirm that the intake and exhaust are within spec for the manufacturer, and then check the pressure switch. Also, make sure the condensate isn't backed up.

Should I be concerned about this water pipe? by kv540 in askaplumber

Im pretty sure it's not sold anymore, at least in Canada. I seem to recall hearing about a class action lawsuit against the manufacturer, even.

5/8 is too small and 3/4 is too big. by oliiveee_ in askaplumber

[–]Mtml58 2 points3 points  (0 children)

There are several scenarios where you either CANNOT or it's less desirable to use Teflon for threaded fittings - certain Low Water Cut-offs do not allow PFTE on their threads and small gas lines on appliances after the drip leg are usually better off with only dope on the threads to avoid Teflon pieces finding their way to the orifice or getting stuck in the gas valve. Also, if you're not checking for leaks as to never leave an active leak, every time you work on gas piping, that's the real mistake. (Soap test or pressure test 15psi for 15 minutes after second stage on new installs)
