Drain pipe from black and grey

[Bob Lawrence]

Hi Marv,
Good to hear from you.
My problem with the rubber coupling is that over time it gets loose.
Twisting a sewer hose on and off and putting the cap on twisting has
caused the rubber to distort.
I guess that was the way the factory did things.
Gonna have to update that area.
Thanks Marv.
