Hey I am searching for a fitting to go into a 1 1/2" normal wall pipe on an in-ground pool gunite... for vacuum. I found (and ordered by mistake) a safety fitting to put on the pipe that closes off the suction when not in use, but It does not accept a regular vacuum hose (too small). Is there either A) an adapter pipe, or b) a correct fitting to do what I want?
I loathe the skimmer adapter plate and want to just plug my hose into the vacuum port on the wall.
The vacuum hose is a normal 1 1/2" nominal hose end.
Thanks for sharing your wisdom and experience!
