This is an example on how we re-plumbed an above ground filtration system. Watertown installed schedule 80 PVC unions to break system down for storing equipment at closing time. We also plumb in gate & check values that can be shut off when servicing the pool pump, filter, heater, and automatic chlorinator systems.
This is so the pool’s water level does not drain back through the pump due to being lower than your pool’s water level. Just cleaning the swimming pool pump basket can be an ordeal without being able to shut the water supply off.
