If you install a maindrain on a pool wall, whats the min. depth from water line to top of maindrain cover?
The minimum depth from the water line to the top of the suction outlet cover is 12″. However, be sure to never install a suction outlet on a seat or stairs where people will use as a chair or back rest. Question: What type of glue and procedure for gluing elongated main drains. Having a problem with pipe blowing out, presently using blue glue and no primer on drain body. Answer: Our channel drain sumps are manufactured with ABS. Use only transitional (typically green) glues when attaching PVC pipe to ABS fittings. Use gray medium set glue when attaching PVC pipe to our PVC based skimmers and double deep sump buckets. In both cases do not ever use blue glue or related hot glues, clear glues or any fast setting cement.
