Plumbing in the Home/plumbing


recently finished my basement. before reno the main waterline was exposed and now with drywall put up the main waterline is now behind drywall. two times the main waterline has froze but i was able to easily thaw it with a blowdryer as i do have an access panel to the shut off valve and was able to get hot air above and below the valve. i am beginning to think i should remove the drywall to keep the main line exposed from the floor to ceiling, but of course it won't look very good. the main water line is only about an inch away from the exterior wall which does not get any sun exposure in winter. there's insulation between the exterior wall and the water line  but obviously isn't preventing freezing. never had this problem when mainline was not behind drywall.

Hey Susan,
Yep, I am afraid that by closing the main line in, you have cut off heat to keep it from freezing.  A solution that comes to mind is to cut out the sheetrock like you did for the valve and run a heat tape around the main line, but you need to have access and a outlet to plug this tape into.  This tape as a built in thermostat that lays up against the pipe and will only heat up when the temp reaches freezing temps.  But you need to be able to keep a check on it so you will need to make a door and space may be against you on installation, this may require 12".

Check this sites out:

Just make sure to read the reviews on proper installation, it may be too close to the wall, it may require 12" so this may not work.  

The only other thing I can suggest is to insulate it even more with insulation as much as you can but if possible, and use a vented panel cover over it instead of a solid panel to allow for more heat to get too it!

I hope this helps and good luck!

I have worked in Electrical Engineering for 30 years in power distribution and am now a Senior Electrical & Instrumentation Designer, but I am a handy homeowner more than anything else and have a lot of skills when it comes to home repairs. Bathroom remodeling, flooring, painting, reconditioning old wood items, plumbing, car repairs and troubleshooting most problems. I think of myself more of a teacher than someone that is going to tell you exactly what you have to do, but I will share as much info as I have to help get your problem fixed, so if you are not interested in learning then don't ask me a question or rate me if you don't like my answers. To me, it is all about the journey so lets share the trail for a short ride and see where it takes us! I also want to give thanks to both my Mom, who has passed and my Dad, who raised us with the "Can Do" attitude and instowed such confidence in not only my life but everyone that ever came in contact with them. You can do anything that you set our minds too if only you can break it down into pieces and just tackle one piece at a time, for the rest will fall into place.


My greatest accomplishment was finishing my first bathroom upgrades in my first home which helped me to sell my home is less than 3 days by myself with a For Sale By Owner sign and no more. Plus I got $10,000 more for it in just 4 years of owning it, now that is great equity.

I am CEO and founder of Spirit Heart Therapeutic Riding Center, inc a 501c3 Non Profit for Rescued Horses and At Risk Kids. It is because of my own Mother intervention, who stepped up and shared her own love of horses with me as an at risk child myself that she planted this seed. So this program was created and is her Legacy that I have been so guided to share with those in need. We teach natural horsemanship to both horse and child and I get to watch some pretty amazing things happen. The kids learn to overcome fears, gain confidence, self-esteem and leadership skills where the horses have a chance at a life where they are trained, loved and respected and become a part of something that saves a child looking for a place to belong. If you support my Dream in bringing this program to life then please Donate to the cause and know that you are touching so many lives by doing so. God Bless You!
