Brand new, inexperienced pool owner here - just learning about all the new equipment at our newly purchased house. Was checking out the pump and noticed some leaves in the filter basket so I opened the cap on the filter basket which released the pressure and all the water starting draining down. Pressure gauge on filter reads 0 now. I've closed and sealed the window/cap to filter basket now. When the pump starts up again (it's on a circuit) will I have caused some damage by letting air in and pressure down the pipes?
Sorry to sound so ignorant.
