Any good pool owner will start the process of opening their pool from the time they first close it for the winter. The cover will likely becom sunk or rain and snow could increase the level of the water. Whenever heavy debris falls in, it’s a good idea to remove it right away, rather than wait until the spring.
Essentially, opening a poool is the opposite of closing it.
All chemicals should be checked to see that they haven’t gone past their expiration date. Any that have should be thrown out in a fashion that is consistent with your municipality’s hazardous waste disposal policy.
The cover should be removed and then sprayed with a hose. Let it dry before folding it away for the summer.
The pump, filter and other equipment needs to be reassembled.
All plugs should be removed and replaced with the outlet fittings.
All diving boards, ladders, slides and various other deck amenities should be refitted. Wipe any equipment clean, particularly the jelly that was put on the metal fittings.
Keep the hose facing into the pool until the water is back up to its normal level.
Restart all cleaning equipment, restore the circuit breakers, time clock trippers, and switches to return to the normal operating positions.
Rebalance all the chemicals in the water once the pool is refilled. Check the levels until they are fully stabalized over several days.
Backwash the filter frequently until the water is clean.
