I want to know what plastic pipe would i use....................?

Question

to put under my driveway? I will be using gerthermal and a compost pile as my heat source so the pipe would have to endure high heat. I will be using a circulating pump also. I want to melt the ice and snow. do you know what specific plastic pipe i could use?

Answer 1

The gray pipe it is sched. 50 pvc and it takes a lot to break it fom freezing etc.

Answer 2

Depending on flow rate of your pump, 1/2'' or 3/4'' pex tubing would be best. It has better characteristics than PVC pipe in terms of flexabilaty and temp. You should consider glycol to avoid freezing/bursting of any lines. Check with your local hardware stores for fittings and pipe. If no luck, talk to a local Plumbing company before you do all of your work and have an issue after the concrete is already in place.

Answer 3

PEX it is used on in floor heat systems. it will survive many freeze thaw cycles. PVC, CPVC,no matter what Sched. will break if it freezes solid only once. They also require fittings for turns the PEX is flexible and can be laid without fittings. I would keep the fittings out from under the drive as this is where failure from freezing would occur

Answer 4

pvc 40 but spend a little more for the galvanized and wrap it with a little bit of pipe freeze wire too ensure no freezing -good luck

Answer 5

At least schedule 40 PVC if you insist on plastic. Sounds like quite a project.

Answer 6

I think that 1/2" I.D. polyvinyl or polypropylene tubing would suffice quite well for that application.

Answer 7

do not use PVC it will not handle hot water. CPVC will

Answer 8

pvc

Answer 9
