    UPDATE: Gas boiler Carbon Monoxide problems after minisplit installation. Opinions needed!

    I would be very worried about this situation. Since you already called several pros, here are some actions that I might contemplate in your shoes: 1) Call your fire dept to investigate. 2) Hire an HVAC engineer to evaluate the situation. 3) Install a direct vent boiler, or retire the system and...

    3-handle shower valve tailpiece

    I've got this, is it the right stuff?

    3-handle shower valve tailpiece

    Thanks gentleman. Is there any concern about using antiseize on the mating surface in a potable water application? Would it work better than megaloc? On the Union threads I do have a copper antiseize I got for working with electrical conduits once. Do you think the antiseize on the threads...

    3-handle shower valve tailpiece

    Ok thanks again for those who responded! I obtained the salvage unit, and it looks like a match. The cost was $300, so it was a gamble, but now that I have it, I can see it has speakman markings on it, and uses speakman stems. So I have two swivels/tailpieces, with what looks like an ancient npt...

    3-handle shower valve tailpiece

    FWIW I think I found a matching assembly on ebay, it wasn't cheap, but probably cheaper and easier than trying to get a part custom made on a lathe if it works. Now when I go to disassemble the union to take take out the damaged swivel, are there any tricks I can use to get it out without...

    UPDATE: Gas boiler Carbon Monoxide problems after minisplit installation. Opinions needed!

    Since it's a ducted unit, it could be creating negative pressure at the boiler, although it could be coincidental. Are you certain the issue only occurs when the air handler is running, and have you had the boiler inspected by a pro to make sure it is working properly? If you can confirm that it...

    3-handle shower valve tailpiece

    Thanks John, I've been hunting for a used one for a while. It's part #09-0059 in the old catalogue picture below, but hasn't been in production for some time. The large nut itself I think is okay, it's a piece speakman calls a swivel, and other brands call the tailpiece. If I could get the valve...

    3-handle shower valve tailpiece

    Thanks John, the problem is the tailpiece, or "adapter" that is npt on one side and union on the other, is split/cracked and has a slow leak. I couldn't get a good angle for a picture, but I'll try again next time I'm there. However it's covered in scale from years of leaking. The split/crack...

    3-handle shower valve tailpiece

    Okay, so you are saying I could try the old coupling nut with a new meter nipple and seal with a washer?

    This sounds fairly genius. I think I can live with a washer seal. It seems much better than a leak. What are the odds the threads would match the threads where the union nut attaches?

    3-handle shower valve tailpiece

    Thanks folks. This is a picture of the same assembly, but it's not mine, I don't have the blue isolation valves underneath, mine are ball valves further away, but otherwise it's the same hardware. I have some pictures, but they are terrible, it's a difficult spot to take a good picture, I will...

    3-handle shower valve tailpiece

    Hi Folks. After some pause due to covid, I'm trying to pickup an old project I am working on with a very old 3 handle tub valve body. I think I posted on this a few years ago, but didn't get much traction during the lockdown, but I thought I'd give it another shot. It has union like tailpiece...

    Hot water heating system pressure

    I said air get sucked in if the pressure is less than the atmospheric pressure, not in general. But if the pressure is very close to atmospheric at the top, air seems to get stuck there.

    Hot water heating system pressure

    It's an nhb 150, Navien. What pressure would you have me run it at? It take 17 to fill the system by the book, but realistically that won't fill the top floor. It just doesn't work, it takes around 21-22psi to bleed the system and get it going. If I bleed it and then drop the pressure eventually...

    Hot water heating system pressure

    I think the pumps are all pumping up, so the dirt mag is just before the return enters the boiler/primary loop. The dirt mag was installed at my request because I asked for an ecm circulator pump and didn't want the magnet to get fouled.
