Great to work with
I used this product to connect Runtal radiators. Very easy to work with, crimps onto connections well, and I have no leaks or complaints about this.

I had no other choice
I had installed the ultra fun product, which I purchased from Supply House. It was so noisy as if critters were crawling in my floors. Since the house was finished except the flooring, I had no other choice than to use this product. No noise and works well. Supply house said they give a discount but have not received one.

Uponor HePe ... Great Priduct!
This is an excellent product for hydronic heating systems. It must be secured at much closer intervals since it does tend to grow with temperature.

Never had a problem with hePex
I've been using hePex for years without any problems. Seems to be a good Type A pex. Supplyhouse delivers quickly and correctly. The few times I've received the wrong part the folks at Supplyhouse have fixed the problem quickly, without any hassle.

Asked by 15 years ago

Q: This tubing has been used to run water from my main house to a shop some 50 feet away. I have two major concerns: The shop water was intended to be potable. ALSO, the line is hooked up to my main water supply in the house with just a shut off valve - is there any way that this water could "back flow" and contaminate the house water??
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffhePEX is not rated for domestic water. If you do not have a backflow preventer installed on the line, then yes, back flow can contaminate the house water.

Q: Can you run this pex in combination with some of the original black iron pipe from the original (circa 1920) hot water boiler. There is original piping behind walls and under floors that I can't get to. Also what would the max operating temp be when using a high efficiency boiler operating at 15 lbs. of pressure?
Asked by Ken 16 years ago
Add your answer
Verified Reply- PexSupply StaffYes, you can use the HePEX in combination with black pipe. The max water temperature for the PEX is 200 degrees F.

Q: Should you use 3/4 tubing for 3/4 baseboards? Would 5/8 be a better choice than 1/2 to supply 3/4 heaters?
Asked by 16 years ago
Add your answer
Verified Reply- PexSupply StaffYou would be able to use either size in the application. The 5/8" would be easier to run, however more fittings are available in the 3/4" size.
