I go to Home Depot near work during lunch and they do not stock any ABS pipe or fittings. None! I know Home Depot sells it online. Weird.
Anyhow I guess I am being stubborn. I can unbolt the new TR38 and leave the back ends off and just rebolt it to the old. Hopefully I did not damage the pipe trying to heat it and get it off.
I forgot to mention another good reason why I opted for the TR38 instead of two new valves. There are no pin connector things on the opening. They used to be there but someone broke them off and clamped a drain pipe on. This trailer was perma parked and rented on occasion. I have another drain valve for the kitchen and it has the same thing so I got a T50 for that one and will put it on the same way.
I have only used the trailer one night so far and dumping the waste water without those pin connectors wasn't fun.
