Have an interesting one. New owner of a home. Issues relates to gray water to septic. First stop in the system is into a grinder pump (in a 75 gallon holding tank). 2" line coming out of the grinder. They have the 2" making a 90 degree turn from the holding tank/grinder into the basement wall to the outside that then 2" pipe continues to septic tank. I have a freeze issue in the line because it was not put below frost line in the first 20-30 feet from the house, which I have identified an in pipe heating solution (heat-line). They suggest putting in an in line wye that would allow the heat line to be put in like where a typical cleanout would be. My issue now is how to get from a 90 degree when it seems pressurized pipe options only come in a 45 wye, versus a DWV option that could be a 45 degree wye combo that would get me to a 90 - but not allowed for pressure it seems. Any options to consider when the 90 is flush with the basement wall currently?
Thank you.
Thank you.
