My pool has a built-in debris collection system that sucks debris from the deep end and collects it in a mesh bag. The bag is in a unit that looks similar to a skimmer - I.E it has plastic round cover that is built into the pool deck. Under that is a round glass cover (about 8.5 inches in diameter)that seals the system.
That cover is cracked. The problem is, I don't know the industry name for the system to find a replacement part. I am hoping someone here might have an idea.
