sunspot rubber tubing and glycol (snomelt)

Leo_G Member Posts: 89
Have to help a buddy from another company. Theclients have a snomelt system, and hired a different company to put a trench drain at the bottom of the driveway. They did not realize that there was tubing throughout. Big mess! Anywho, it is sunspot rubber tubing, the original company shut down about 5 years ago, and now I have been "hired" by this third company to help repair the mess. I had some info a few years back about the type of glycol to use with this rubber tubing, but can't find it anymore.

Anyone out there able to help me, help my buddy, help the drainage company?  LOL!

thanx in advance,

Leo G

    got a picture?

    I haven't heard that name before. Is it a thin EPDM or a manufactured hose like the Watts or old Heatway.

    Usually PG is sage to use in about any heating system. Does it have an O2 barrier, do you know?

    am heading up there in about an hour, will take pics then. Yes it has a very thin aluminum foil oxy barrier. Can't remember if it is EPDM or not.
