Hi. I'm a pool "newbie" and just noticed that the Universal Wall Fitting does not screw all the way in the return line on my new pool. It sticks out and there's more than a 1/4 inch left to go. The cleaner plugs in and works fine, but to me it looks bad and could be a hazard. My builder said that's "normal." Am I crazy for not believing that? Obviously there's not enough thread in the return pipe to take the whole thing. What can be done at this point? Add more threading to the return pipe? (sounds risky) Cut 3/8 inches off the universal wall fitting?
