 Frozen pipes remedy
Author: gasser (PA)

I have pipes running thru unheated crawl space to 1/2 bath and laundry room. During extreme cold, have freezing of supply lines and drain(trap) inside exterior wall and in crawl space. Got some relief by opening up drywall (nice) behind washer to let pipes see room heat. But there is still freezing going on below.

Do those heater tape gizmos work? How much juice do they use? I could use those for supply(copper) but drains are PVC. The drain thats freezing is the washer; I could move the trap up and into the room so it would see room heat and use the heater tape on supply lines...OR

Try to insulate, heat crawl space which has gravel/dirt floor and block walls... Is this even feasible? I would need sprayed on foam stuff and probably another furnace of some sort. This would have the added benefit of warming the room above, but the floor is insulated so ??? Anyway, looks like big $$$.

Any thoughts?

for one. most codes require the trap to be above the floor. as for the pipes i would suggest heat tape but cant remember the type the guys from your neck of the woods recommend so just wait a few and one of them will be by shortly

Code? This house was built by Larry, Moe and Curly on a budget...

Heat tape and move trap looks doable...

Thanks.

i dont care who it was built by. most areas of the country require inspections and that requires going by a code

Every mobile home in the northern hemisphere of the US and canada has a *heat tape* on the cold water pipe coming into the home. My mobile home in vermont, has a electrical outlet underneith the house spicifically for this. I have had a heat tape on my home since 1984, Ive only had to change it once. The style I have can be purchased at your local hardware store, it looks like a extension cord but with a thermostat built into it. I think it ran about $80 at that time. For a 20 foot cord. Only put it on copper pipeing. And then insulate with wrap insulation.

Heat tapes work. Buy Frost-tex brand. it's save and you can get it with a thermostat so it only runs when it's freezing.

have larry, moe and curly come back and move the pipes up into the joist space in the crawl. insulate below them but not above them. also, move them out of the outside wall and run them exposed. behind the washer they can show and under the toilet they can be chrome.
get a properly wired (220V) electric heater, set it for 40DEG and put it under the area that has the problem.

The stooges are long gone, house is 15 yrs old...

Pipes are up btn joists, were insulated from below as you said. Room above is not real warm as it has 2 exterior walls + 1 wall to unheated garage. That + running pipe thru ext wall = problem. I will get some of the tape and move supply out of walls if neccesary. An move trap up into room.

A 220V heater would be nice, but I dont have money to burn trying to heat this uninsulated space.

Thanks, terrific forum!

Just go with the heat tape and insulate the pipes. should run you around 50 bucks or so.
