Subject: winterize pool
Question
I have a 13000 gal in ground pool which I am closing myself. Do I need to bring in the pump and motor, along with the filter housing and the filters, or if drained can they stay outside? I live near the dc area. I used a bottle of compressed nitrogen to blow out my lines, but it runs out to fast. what kind of a compressor or size is best? do I need to put anti freeze, the right kind in my lines including the main drain/ I also have a water fall.
Answer
Although the pump is designed to operate outdoors... I typically take the motor inside in a dry warm place...it will prolong the equipment. It is okay to leave the filter outside.
In order to blow out the lines... buy a 1 hp air compressor at home depot.... remove the pressure gauge on the filter...connect the air compressor to the threaded hole... turn compressor on... open all of your lines. The air will start bubbling from the closest point. Use a rubber plug to plug. The air will go to the next closest exit point. Work your way around the pool. Typically, the main drain is the last to go. You winterize the drain by turning the main drain valve off which will trap the air in the pipe and prevent water from getting in. After you close the valve, make you you QUICKLY open another winterization plug by the system in order to relieve the air pressure. If not a plug will blow.
Place empty 1 qt size bottles 1/2 way filled with sand in your skimmers. This will prevent cracking in your skimmers.
Also, make sure you clean your pool, balance the chems and shock the pool before closing.
Good luck.

PS If remotely unsure... hire someone to do it... its not work cracking a pipe.
