We just bought a house with an inground 36 X 16 pool. Opened it not too long ago, and while cleaning the patio(which is exposed aggregate) around the pool found that the drains did not drain. Tried a plumbers snake and only got down a couple feet. We have a A LOT of pine needles, bugs and **** that accumulate in the area. Does anyone know a good way to fix this by yourself, or am I calling a plumber?
