Yeah I will, thanks. This clamp was made for the ci apparently (they didn't have the one I had looked up online and didn't realize the difference). Hopefully won't be a next time. I do think the upper will be fine, it's tight on both sections. Bottom I can keep an eye on and get to easily.

Thanks. This is for CI, so if anything the issue should have been fitting the PVC. At this point I think I'll do more harm than good by trying to swap out the rubber. I may still swap out the sleeve. Not sure why it fit no problem up top but had an issue with the bottom connection.

So what's the difference between those? Corrugated vs not? I can replace the collar easily enough, the rubber part not so much, correct? However, my wife isn't thrilled about having that as an accent wall, so it's going to have to be repaired. At any rate, that upper connection at least appears...

Just as a follow up...wow, that sucked. I bought a snap cutter that ended up splitting the pipe worse, extending it upwards. The pipe at that location was very brittle/thin. Strangely, above and below looked fine. The snap cutter couldn't get behind the pipe higher up. I ended up grinding the...

Well thinking about this a bit more. I'll be cutting below the second floor, so it should be supported above that. At least there'll be a bunch of pipes branching off that will support it . I didn't see any collar above the first floor, but the pipe does a 90' resting on brick/framing. Which...

I have a crack in my soil stack between the first and second floor. I assume the pipe runs vertically, venting through the roof. On the second floor, there are 2 full baths that share a wall. Most of the fixtures are not in proximity to the main pipe, and I have no idea what type of connections...

Bump?

I've been on the 8 year plan for finishing my basement. But THIS is the year I actually do it. As part of it, I'm going to be putting in a bathroom. The house is 100+ ;years old, so who knows what's going on. However, I have floor drains, and presumably a cast pipe going down the center of the...

Am about to install a new Rheem Platinum gas WH to replace my 40 gal 1988 (!) unit, which has recently started leaking. I believe the new unit has integral heat traps (there is plastic inside the metal nipples). The manual says "some water heaters have been supplied with[...]heat traps. These...

Oh, and can I use PEX to connect my supply lines?

I'm thinking about replacing my 25+ yo 40 gallon heater with a tankless model. Been looking at this one. I currently have 3/4" gas to the old heater (my whole house is I think under-supplied with 3/4" main, but the city keeps on insisting that it isn't...), and 1/2" water. It's vented through...

Done. The voltage between the R wires is now 3vac. I get 24v between the TV and Z/T terminals. However, I get 24v between Z/T and ground--Doesn't this mean that the system isn't isolated and I have a problem? So, aside from being careful to turn of both units when servicing, any other...

Found it! Here's the setup for my boiler. I think I've figured out all the components in my boiler system. My initial pic was of the ignition control module. Second pic is the transformer--that switch above the relay is the aquastat. Fig. 11 is my setup, except that my ignition module...

Not sure what's a center tap? Behind the tag there's a screw terminal labeled "W". Underneath all 3 terminals is "thermostat". The black wire goes to a terminal "Z".

Oh, I know I'm overthinking things (see last post). Which is causing me to get confused over multiple simple things. But I don't have a separate power supply for the stat. I could add one, but I'd like to KISS.

OK, so looking back there a bit more, it would appear that I'm measuring from the wrong terminals. Not sure what the box is posted above, but took another pic of what I think is relevant. So on the below picture, I get 24v to ground from the blue and black wires, and 24v from blue to yellow...

Most of the Wifi stats that I've seen have some sort of web interface or proprietary app. This one is really cheap, and would work very well for most installations. I've had it for 2 years controlling a heat pump. I'm only replacing it because I can't fine tune the aux heat. BTW...

Heard back from customer service at motison. They said that if I have no voltage between the 2 R wires, then I can connect them both to the R terminal on the stat. Unfortunately, I have 50v between them. I also checked voltage from the secondaries of the transformer in the furnace--with both...

Right, although I'm thinking of ground in this case as just a return path for current. How do I find that out? Well, I hooked up both 24v wires to the R terminal of the Lennox stat. From R to C I get 28v (which was the voltage from the a/c unit). From R to W I get 24v (the voltage I was...

I may have my answer. This article was very helpful, particularly the diagram on page 8. While I was correct in my assumption that the 24v powers a relay, I had thought that the negative terminal of the relay was connected somehow to the 120v circuit. It appears that it is instead connected...
