I believe the toilet is dripping into the main line and if it's out of use for a couple of days when it is cold outside it is forming an ice blockage in the main line.
What steps can I take to stop this from happening?
I'm wondering if it's being used as the expansion tank for the water heater. However, there is no backflow preventer into the municipal water system (not required here) so I'm wondering if the system would need the toilet for expansion.
Over a few cold days it froze a 4" line completely solid (in the basement).
Where do I start?
Thank you,
Bill
