Hello everyone.  I have had a Mahoning 300 for three and a half years now.  When I installed the unit I ran the pex in corragated pipe.  Over the years it has been installed the corragated pipe has developed a hole in it.  When we get a lot of wet weather, water will leak into my basement.  I have attempted to caulk where the pex enters the basement.  Due to the pex expanding and contracting I still have a small leak.  Any ideas what I could use to fill this area in my block to stop the small water issue?

If you have water inside the corrugated pipe you should replace it. You are losing a ton of heat into the ground because of the water.

Wait till spring and dig up the lines and replace.Like RSI said you will lose to much heat in the ground water.

depends where the hole is and how much of your line is under water on how much heat you are losing. when we ever get any snow or hard frost you will likley see the ground over top of your pipes thawed out. perhaps if this leak  is close to your house the loss may be minimul? i was not so lucky my whole 250 feet would thaw out 3 feet wide, taht was costing me about 4 cords of wood each year

good luck with your pipes

If the corrugated pipe isn't metal, how does a hole occur?

I think he is using a type of non-perforated black drain tile.  (hopefully non-perforated!)

Sharp rocks?  Flint?  Foreign objects?  I've dig out piles of scrap metal before that owners never knew was in there yard
