My brother has plumbing business in. Lamont Iowa and he’s been using pex for years..But recently they have switched to WIRSBO fitting- which require an expander,as well as a special crimper—which are costly.. The main reason for switching is because of having a problems with leaking fitting after a while, plus these fitting allow a full flow of water without restriction from fitting size. Since he switched to new type fitting has not experienced any problems with leaking fittings.

[...] plumbing is well underway, with most of the drains and vents already in place. As I mentioned back in May (I can’t believe it was that long ago), we’ll be running PEX throughout the [...]

Hey Sam – no, this won’t fix your problem… the plastic pipes aren’t insulated and are still susceptible to freezing. your best bet would be to insulate the pipes you’ve got (or try to reroute them along an interior wall).

Eric has a good point, a recirc. loop in your home is an excellent idea especially if your heating source is a distance away from any particular fixture. The cost of the pump and the extra piping for the loop should pay for itself in a couple of years (my guess). Plus you have less water down the drain waiting for the hot to arrive. The pex has good insulating qualities but you could add some insulation on the recirc loop as well.

Reading the above, I’d just like to add another option: a “loop” system whereby hot water is constantly (more or less) pumped through a loop that visits every fixture, thus reducing the delay of getting hot water out of the faucets. It’s more expensive to run because of the extra pump, so it’s likely less green, but you have much less a wait for hot water.

Also, a friend warned me that some copper piping uses extra thin copper, which can fail, so beware.

And it’s always good to concern yourself with quiet soil pipes, as plastic is noisy and once the walls are closed, the noise cannot be reduced. A quiet house is priceless.

I’m wondering how much sound proofing the sprayfoam might provide? I’m pretty sure we’ll foam in and around the pipes (at least some of them…), so they should be all sealed up, which should help. If not, the loaded vinyl sounds like a solid option as well.

Thanks for the tips!

I used cast iron waste pipes due to the noise problem. But you can also try insulating the plastic waste pipes with something like ‘loaded vinyl’ which is a sound barrier. Otherwise they do make a lot of noise when the toilet is flushed.

I am not suggesting that you “must” use cast iron, but I will give you one piece of advice, from personal experience. Be very “careful” where you route your waste pipes. (I may not be using the term correctly. By “waste pipes” I mean both the toilet waste pipe as well as the shower / bathtub drain pipe.)
I have had personal experience of thin drywall, plastic waste pipes, little or no sound insulation and waste pipes that were routed literally in the wall in the dining room.
We would be enjoying lunch or dinner with guests in the dining room and one of the kids would flush the toilet in their bathroom which was directly above the dining room on the second floor. The sound of the toilet flush was not bad, but the sound of the water running down the waste pipe in the wall was awful. You could actually hear the water rush and then trickle through the wall while in the dining room.
I have been in other houses where the waste pipes run through less “embarrassing” locations. We cut open the drywall and replaced a portion of the waste pipe with cast iron and it made a huge difference. So either, carefully plan where your waste pipes will go (to the extent possible) or alternatively, selectively use cast iron where warranted.(We just bought a new property and will be starting construction in the spring so I plan on being a regular visitor to your excellent site!)
