I have a brand new pool, and purchased it with an in-floor cleaning system from Paramount. My problem is with the MDXr3 drain not having any suction.
When the salesman explained the system to me he told me that these drains had so much suction that they had to install two safety mechanisms along with it to keep people from drowning (I was impressed).
Anyway, the pool is now built and I decided to chance my life and get near this man made "black hole" and I have to say that I was suddenly very unimpressed. I didn't feel any suction, I went so far as to put a leaf within 6 inches of the inlet and it just blew away from drain. I grabbed my little leaf and stuffed it directly into the drain, and that did get pulled to the waste canister.
I called my PB and they showed up and promptly blew out the lines between the canister and drain, they didn't find any obstructions. They told me the system was operating normally and that I would have to shut off my skimmers to force more suction from the drain. They piped my system in such a way that I can only shut-off one of the two skimmers at a time, and as you can guess, this made little to no difference to the main.
I've cleaned my cartridge filters and checked for obstructions at the impeller but I'm still getting no suction.
I was hoping someone out there with a similar system could tell me what their experience was with the drain. Maybe I'm expecting more suction than it was designed for?
