help! does pvc underground hvac vent pipes carcinogenic?
We are suppose to pour our new home 1st floor (no basement) concrete tomorrow 16apr over the HVAC venting pipes. But... Saw today that they used huge 10" PVC venting pipes to heat/cool the rooms. I read PVC contains BPA! Will it be released into the air I breath with all the moisture laidened heated and cooled air? Is this safe? It is a full ICF home so it is REALLY tightly sealed with a metal roof. I need the answer tonight. I am desperate for help! Thank you.
P.s. My builder is touted to be a Green builder (not). They didn't even ask us if this would be a concern. This 1st floor level is being heated with the ducts coming up from the floor since we were told it was a better heating solution for this floor. We live in Ohio
