I am hoping that someone knows of a dimming system that will work for me... I built a bookcase and am in the process of planning a low voltage lighting system. There will be 3 separately controlled...

Yumbrad,

Out of sheer curiosity, I did a search for a book of plumbing theory... There is a series of books called Questions and Answers on the Practice of Sanitary Plumbing by Robert Macy...

First, thanks to all who replied.

Yes, I learned from a phone conversation with the company and subsequently their instruction sheet that the tub is supposed to be caulked to the floor... As one...

Hi HJ,

Thank you for the response.

It dawned on me that it might be a good idea to call the company to see if they had an answer. They say the tub is designed to be siliconed to the finish...

I am in the planning stages of a bathroom remodel. We are looking at a tub made by a company called Victoria & Albert Bath LLC. The model is called 'Ios'. Here is a web page that shows the tub:...

Question for HJ

HJ, can you explain the difference between a PVC compression coupling and a Dresser coupling? I looked up images online and to the untrained eye they appear to be similar. Thank...

I tried to attach another picture... this time with the female section of the tool inverted. This will show the space between the male and female which allows the presence of the pipe. So the...

Here is a picture of the tool I found that is the re-rounding device. I assume the outer shell is placed over the pipe, then the inner cylinder is tapped in. The instructions on the Swigtools (a...

Thanks for the quick responses. Based on your info I found a great tool made by Reed Tool. Its model number is RCR 341. I guess it's called a 'Re-rounder'. It looks like a bolt cutter but the...

Today I helped a friend repair a hot water re-circulation line under a slab in an apartment building he owns. Apparently, the pump ran 24/7 for years and now this line has leaks. The line is 3/4...

Thank you, Hackney. I'm still curious, though. If there isn't an opportunity to wash a vent such as the one depicted in the photo... then what? Would that installation fail an inspection? Would...

I am reviving this thread because I'd like to learn more about venting a toilet when it is on a slab. The picture that the OP posted caught my eye because it looks like this line is vented by what...

HJ,

I was surprised at your poor review of epoxy coated pipe for gas. I always thought that was pretty sturdy. Obviously local codes would dictate but I'm curious to know your preferred material...

MT,

Yes, I believe I see what you're referring to. Always learning! Thank you!

Hammerlane,

I've been under the impression that san t's are inverted if they are venting something. I don't know the reason for this, but that's what I always thought. Is this incorrect? Also,...

I'm curious to learn more about flare fittings. Could one of the pros describe how this is accomplished and perhaps even post a picture of the tool used to accomplish this? Is a flare fitting...

MT,

I think I understand the logic of why the latest version will work, as you say it will, but I'm curious about your statement that some of the fittings are 'backwards'. For the life of me, I...

While copper seems to hold up well against the corrosive nature of concrete, there may be an issue with thermal expansion and abrasion if the pipe is totally encased, especially at points of entry...

You mentioned that Chicago has an 'interesting' sewer system. I'm curious to learn more about this. What makes this system distinctive? Thanks in advance.

This thread prompted me to find out more about Orangeburg pipe. I found an interesting website that tells its history and definition. Thought I would pass it along.
...

I have a question of a conceptual nature regarding the picture in post #7. As I understand it, it's against the rules to have a vent take a horizontal trajectory unless you're at least 6 inches...

I am hoping we can pursue this thread a bit in the spirit of learning more about how venting works and why. If I recall correctly, in previous threads about venting it was explained that the primary...

Tom,

I post this in the spirit of continuing education and not meaning in any way to fan flames. Could you take another look at Plumber 2011's post #6? Isn't that flat vent washed by BOTH the...

Tom, I'm curious about something you said in a few posts up in this thread. You said that a toilet does not need a vent to operate. I guess this makes sense because a toilet evacuates via a siphon,...

I am posting in the spirit of advancing -- hopefully not hijacking -- this interesting thread.

Plumber 2011, I'm curious why your area requires a double sanitary t, instead of a double...
