Is there any reason that a dedicated pressure return cannot be hard plumbed? I am helping a friend recover their pool and have noticed that the Polaris pressure hoses for this application have become unservicable. The suction side has collasped and is entraining air. It uses a Polaris 3/4 hp booster pump and is going into a 1 1/2" return line. The hoses currently used are about 3/4" in diameter. Would it matter if the piping was larger than 3/4"? I would imagine that it wouldn't matter as long as there was sufficient pressure to operate the 360 cleaner.
I tried the Polaris web site, but couldn't find any plumbing instructions.
Thanks for the responses.
