How To Close A Swimming Pool - Winterizing Your Pool


During the summer months, a refreshing pool is a great way to stay cool and spend time comfortable outdoors. Pools are also great entertainment providers, and many households with large, beautiful swimming pools will host friends and families at backyard barbecues and lawn parties. A swimming pool is a huge investment, and many homeowners forget to effectively protect this investment during the winter months. If you own a pool and you fail to winterize it, the subzero temperatures and lack of regular use can lead to serious damage that can cost thousands of dollars to repair. Pipes and pumps can freeze and burst, pool lining can be damaged, cracks and discoloration can affect the look of your pool, and other problems can occur without proper winterization. Following these easy steps or hiring a professional to winterize your pool will protect your source of cool, summer fun during the long, harsh winter.

Adjust Chemicals

The first thing to do when winterizing the pool is to adjust the chemical levels in the pool water. Because chlorine can slowly break down some pool covers and algaecides during the winter months, the concentration of chlorine should be adjusted so that it is lower in the winter months than it is during regular use. You can begin the winterization process by shocking your pool with chlorine. After the water has readjusted to the correct chlorine levels, you can add an algaecide specifically designed for winterization.

Remove Fittings and Accessories

It is a good idea to remove all the fittings and accessories from inside your pool. Jet casings, pool ladders, skimmer baskets, and pool cleaners should all be removed to eliminate crevices and corners where algae can grow and thrive.

Adjust Water Level and Drain Pump System

To drain the pump system of a pool you must first lower the water level of a pool to below the jet system if you are using a floating pool cover. Some pool covers do not need to be used on a pool that has had the water lowered. After the water level is lowered in your pool, you can use an air compressor to blast water out of the piping system. If this is not done correctly, however, extensive damage to your pump system can occur.

Lubricate Fittings

You may want to make lubrication a regular part of your winterization treatment. Applying lubrication to the pump system of your pool is a good way to prevent metal components from freezing tight during the winter months. Because metal expands and contracts so rapidly during large fluctuations in temperature, the adjustable parts of your pump system may become fused together if they aren't well lubricated. Then, during the summer months, you may be unable to adjust a poop pump system without breaking some of the components. You can find lubrication that is specially formulated for pool systems or use any basic type of lubricant.

Winterize Plumbing

It is a good idea to effectively winterize the plumbing that is used for your pool to prevent pipes from filling up with water, freezing and then breaking. Broken pipes can be a headache to repair and can seriously delay your pool usage when the summer comes again. You can winterize pipes by adding foam insulation to the outside of the pipes which will protect the water inside from freezing. For pipes that are going to be exposed to continual subzero temperatures, you may have to invest in heat tape. This tape is specially designed to recognize significant drops in temperature and heat up to prevent water from freezing. You can find pipe winterization materials at a local hardware store.
