I have a Polaris 380 with an over the deck feed line from the booster pump. The line was run by the previous homeowners underground but then it comes up to run "over the deck" and feeds into the pool. The covered the line with concrete but the ends that are exposed are both pvc but I don't know if the entire pipe is pvc of if they used a HD hose. Regardless the exposed pvc has hairline cracks and is leaking. I tried to do an easy repair using Water Weld but it just created leaks in other spots of the exposed pipe. My two questions are this --
1.) Is it better to use a HD hose or to go the route that the previous owners did and use pvc with a metal shut-off valve and then cover again with concrete?
2.) Should the pressure relief valve be installed underwater? Currently the pvc pipe sits on the side of the pool, not it in, and then the Polaris in connected above water instead of with an elbow and pipe running down into the pool as all the diagrams show.
I've attached a picture of the water leaking from the pipe near the metal valve (yes I know trying to use Water Weld wasn't the best idea).pool.jpg
