will this keep a 4" pvc pipe from freezing?

That depends on a number of variables. It will keep a 4" pipe from freezing if it is not exposed and it isn't extremely cold. It will keep it warm enough if it is 0 or warmer. Smaller pipes are actually more prone to freezing than larger ones. The best way to ensure it won't freeze is to keep the water in the line moving.

Don't really know but I put the tape on my trailer water tank to keep it from freezing while hunting in Colorado, this fall, and it worked just fine. The temp did fall below zero and while the generator was running I plugged it in to the cord and heated the plastic water tank. This kept the temp in the tank about 45 in the night. Nothing froze and nothing broke so i guess it worked.

Keep in mind I'm just a do-it-yourselfer homeowner, not a plumbing/sprinkler professional. For attaching to PVC, I used (1"?) threaded adapters (wrapped PVC threads with Teflon tape) with appropriate sized outlet. Tape and tighten threaded adapters, dry fit PVC pieces then clean/glue. In my case, I assembled to sprinkler system inlet PVC first then to the outlet plumbing to assure alignment between Febco adapter/outlet and sprinkler PVC line (that is, between the downstream portion of the Febco and existing PVC). If you expect sub-freezing temps, I've used heat tape/insulation around inlet/outlet valves and body. Febco has downloadable freezing precautions.

The description states "Not for use with ice makers" This indicates it cannot handle pressures above about 30 psi. Clear PVC braided tubing, which can handle high pressures, starts at 3/8 inch inside diameter. So if you need line that can handle higher pressures at this diameter you're probably going to need to get some Pex line or copper.

According to manufacturer's info on package, it can be used on PVC pipe. They recommend wrapping with insulation to hold in the heat, however in the case of PVC pipe, I would not seal it off at either end for fear that it would retain too much heat.

It might help if you use very hot water. I don't think it is designed to push ice out of a pipe. However it works great when trying to move organic material.

I believe they leave room for expansion so it doesn't crack when freezing. Mine has a gap also, not 1.5 inches, but close to an inch. As long as it does not leak out it should be fine!

This wrap is a great insulator. As long as the heat is low enough so that the plastic inside does not burn, it should work fine. If you are wrapping duct work it will work great. It is not for exhaust vent piping, which even double-walled would still be too high a temperature.

It should mine is in 5 inch pvc I have plenty of room around the pvc pipeing and the pump is around 3inches in diameter my well is onl;y 100 ft deep and pump is set at 60 feet I wouldn't worry about setting it in 4inch pvc as long as there is plenty of water I use it for watering yard

not sure , I don't know the OD of 4 inch PVC , measure the OD of your pipe and compare it to the OD of 4 inch galvanized vent pipe at Home Depot or someplace .

No. It is not designed for freezing. Also the metal locking parts may become very brittle. Try a softer plastic designed for freezing.

I used it as such recently when we had those sub zero degree days. Keep in mind that it does not get SUPER hot, so though it wont melt right through the plastic, if left on for a long period of time (days/weeks), it can destroy the integrity of the plastic and possibly make it "droopy" or bend slightly as the cable has some weight to it. I'd say , fom experiance, if such a pipe is freezing and/or frozen, using it to thaw the pipe should cause no issues. I'll check the installation guide that came with it and if it happens to say different, I will repost. FYI : it works great on standard copper piping and such.

Yes. We have over 1000 feet of pipe that is protected by it. You have to insulate the pipe with a proper insulating blanket to allow the defrost to take place and or protection from frost. Highly recommend this particular product.

I attach these to my outside faucets to somewhat purify my dogs water. In the winter, I completely take them off and wrap my hydrants. Sorry that I could be more help. I would figure they would freeze though unless you alowed a large amount of water to flow through them.

Yes, I am having a great success with this unit, it has been extremely cold winter, it has keep my pipes from freezing. Very easy to install

I mounted mine on a 3/4" PVC pipe. It's mounted in the attic so PVC should be fine for that application. I don't think it would accept a much larger pipe

All I did was wrap it around the pipe and double insulated it with M-D Building Products 2378 Foil Backed Pipe Wrap and M-D Building Products 4929 3-inches-by-25-Feet Fiberglass Pipe Wrap I bought here at the time I got this tape. I also used a Farm Innovators Cord Connect Water-Tight Cord Lock for the electrical extension and it's already been tested to -13 below 0 and it's worked without having to let the water trickle all night and no pipe freeze ups.

I have cut up to 6 inch plastic pipe. 4 inch should be no trouble. you will have to put a block behind the pipe in order to reach the fence.
