The only replacement that might have been done would be to replace the diaphragm. I don't think a dual filter version was installed.

I'm not 100% sure but I think the manufacturer is Zurn.

Hi,
My local church has a few urinals that periodically (2-3 times per year?, maybe more because sometimes problems are not reported to me) run without stopping. The solution has been to hit the...

I'm part of a committee that is trying to come up with the specifications for adding two bathrooms to my church. One of the design decisions is hot water baseboard heat versus electric baseboard...

My local church is looking to put in two new bathrooms in the basement so that restroom facilities are more accessible to the food pantry clients. I'm part of a committee that is trying to come up...

What about using RV anti-freeze? That's what my in-laws use to winterize pipes in a summer house in VT.

Thanks again for the help, nhmaster.

I was looking at your profile. You already posted 1000+ times, an average of 6 posts a day. Very impressive!

Thanks nhmaster. That seems to have done the trick. Do you think it is likely that the problem might occur again before the end of the heating season?

In any case, I plan to open up both valves...

About a couple of days ago, we developed a problem with our heating system where one zone continues to put out heat even though the circulator pump is off. I believe the issue to be the Taco 241...

I completed the project about a month ago but I'm just getting around to posting my feedback.

Per jadnashua's suggestion, I used a Brasscraft angle stop with a chrome pipe after unsweating the...

BINGO! I think you're right that I have something similar to this. I checked their Speedway catalog and sure enough it's there. I went upstairs and looked at the valve handle and it says Brass Craft....

Verdeboy,

The reason that I want to unsweat the pipe is to avoid opening up the wall. I was going to clean it up, solder on a female adapter, and then thread a 1/2" chrome nipple. A new shroud...

Hi HJ, I'll try to post a better picture tonight. I'm not sure that it's a retrofit because all three toilets are plumbed similarly. The toilets are all original to the house.

I looked at the...

Hi Jimbo,

This is a gray area for me. I understand the reasons you need to be a licensed plumber in Mass when doing gas fitting or implementing new supply/drains as it protects the public.

It...

I would like to avoid opening the wall if possible. If I went that route, I would put a drop-ear elbow with female threads and secure it to some blocking.

In case it wasn't clear, I'm referring...

I'm in the middle of a project where I'm painting the bathroom. To make it easier for me, I pulled the toilet out. Plus, I intended to replace the "nipple" since it was painted and I want the chrome...

Could you take a picture or two of the room to show us where the dead space with the pipes are located? I'm having a hard time visuallizing what this space looks like.

I noticed that the bleeder valves are placed on the 90 deg elbow when the pipe transition from horizontal to vertical. I guess when the water goes down, air tends to rise and stay trapped in the...

Thanks for the reminder. I should have looked at the responses to my previous posting.

I ended up doing what you suggested. That is to run the garden hose outside and flushing it for about 5...

My system has a supply manifold with three circulator pumps and isolation valves. There is a return manifold with a boiler drain and isolation valve for each zone.

From reading the archived posts...

On my boiler (Weil-McLain CGa5) , I have a temperature/pressure gauge on the supply side. There's no gauge on the return side. In the manual, it stresses that the return temp should not be less...

I have another question on black pipe assembly.

Let's say that you are trying to put a directional T on a line and tightened it such that it won't move any more (without using a cheater) but you...

I'm progressing along nicely with this project. Tonight I added onto the supply manifold for the 3rd zone. I also added a little bit of copper.

Knock on wood but no leaks so far. The only tricky...

Thanks for the tips. I was afraid of overtightening it but I think I understand now.

The original idea was to ensure that the lines were completely free of water prior to sweating. I guess it's overkill. I probably should just drain the pipes and where I need to break the existing...

I have some questions on black pipe assembly.

What do you do if you're trying to put a T on the pipe and it needs to be aligned in a certain direction?

So if I put the fitting on hand-tite and...
