Re: leaking return line
And if the Bank Account is unlimited there is always Mega Press and Pro Press. But if it was my $$$$ 1" sweat copper will do most houses.
We had a High School with an addition that was fed with underground steam and condensate and the condensate line failed. I think the old condensate line was 2 1/2" or 3". We pulled a 1 1/2" rubber hose through it and it worked fine.
This school was being torn down and a new one built so the hose only had to get them through 1 winter.
Re: leaking return line
For what it's worth, when I had a wet return which leaked like a sieve (really rather funny to look at)! I replaced it all with copper. Same nominal size, same elevation. No problem. That was about 30 years ago…
Re: Single Zone mini- labor grabber
@EdTheHeaterMan this very topic is what I enjoy most about being a small business person. It’s impossible for the average homeowner to understand all the nuance, jargon, technicality.
I have one fond memory I’ll never forget- this older woman, perhaps 20 years ago, was talking to talk as if she was a coworker.
once in a while, I’ll be talking with someone that’s desperately trying to sound like they know what they’re talking about, and they try too hard. Of course I roll with it, but it’s the exact opposite of the nice old lady from 20 years ago.
Just about everybody else is in the middle, just trying to understand and asking questions. Combine all that with the unique and bizarre technicalities of our state’s high-efficiency program: the conversations get pretty technical.
so, I enjoy the communication process, trying to transfer this HVC stuff to non-technical people
I’m in my late 50s, at some point I need to deal with Retirement funding and such (tax exposure etc) All that language makes my head hurt.
“the customer is always right”, I never fully agreed with that sentiment. If they’re wrong, I will carefully point that out

Re: Mixing valves in oil fired radiant floor heating system
I guess the first decision is which fuel is going to be used?
If it is LP a mod con is my suggestion, I believe they all have ODR
If it is oil, the Viessmann oil also includes ODR. Some. Viessmanns have a basic return protection function, a simple aquastat that holds the pump off if return drops too low. although the ODR control may include return protection also.
Download the manual, Viessmann usually has top notch control logic onboard
What is the heat load for the completed project? The smallest Vittorond may be too large? Another reason to consider a mod con on LP. The modulation alone is worth the consideration

Re: 3 and 1 1/2 ton finally done
No I didn't have to pump it because I had an open/atmospheric loop pump. I was able to just pour it in. And it was the food grade stuff, not dangerous to my knowledge
Re: 3 and 1 1/2 ton finally done
Took out 2 hydro air systems and replaced them with GEO heat pumps and removed boiler if I understand correctly.
Usually the removed equipment is trashed. This removed equipment could go in a new house!!!
Re: 3 and 1 1/2 ton finally done
Thanks @EBEBRATT-Ed for that comment. At a closer look, I see that First Co. air handlers were replaced by the Water Furnace air handlers. Now I get it.

Do your best to keep it reasonably clean.
That's about all you can do with anything that spends it's entire life at 100% RH.

Re: leaking return line
Copper or black pipe. You've been told and it has been explained. If you want to use plastic, you might as well use garden hose. That will be cheap and last a few years too.
Black is cheaper than copper, but with the cost of fittings and labor will be more expensive. Black pipe will last 75 years; copper maybe 75 - 100.
Most residential customers care more about their counter tops than their heating system. A conscientious pre-purchase inspection might have netted a handsome credit for the leaky returns. If it was missed b y the "inspector," you may have some recourse.
Plastic pipe will fall apart quickly and get you or your plumber called a hack.
Re: leaking return line
A couple of general comments.
First, don't just replace the leaking section. Replace all the pipe which is in a similar setting at one go. Yes, the material cost will be greater — but the ultimate material cost will be the same, and the labour cost less. You'll only have to do the job once.
Second, there are two problems in my view with CPVC. The first is that it is possible, though I'll agree unlikely, that steam or very hot condensate might get into the pipe. The cpvc simply can't handle that temperature. The second is that a pipe down low, near the floor, is vulnerable to damage. Copper or iron won't break. CPVC might…
