Summer is ending, winter is near, and the pool season is coming to a close. Pool maintenance in the winter is really easy if you close your pool right. Whether that means draining some of the water before you cover it or completely tearing it down and putting it away depends on the pool that you have. If you’re scared of closing your pool on your own, probably best to call a service tech.
RISKS INVOLVED & ENVIRONMENTAL CONCERNS INVOLVED IN IMPROPER DRAINING
- Draining all pool water incorrectly can cause severe damage to your pool structure. Water is drained into the ground and sometimes you have the risk of creating all water force below the ground to force water upward.
- Dumping water into sewage lines runs the risk of too much water overflowing and potentially backing up into the house.
- In case of a vinyl pool, draining pool water entirely puts the whole liner at risk for rips, tears and other damages from debris throughout the winter months.
- Chemically treated pool water may damage some plants that are sensitive to salt and other chemicals
- When chlorine rich swimming pool water is discharged directly into surface waters including rivers and lakes, it can negatively impact our waterways and be toxic to fish and other wildlife.
Here are some to-do lists to mitigate the risks involved while draining your pool:
Checklist for draining your pool:
- Close the return line to your pool: Check to make sure that air is not let inside the suction pipe as water levels come down. If the air is let in then water will stop flowing. It is better to know where to dump your wastewater.
- Open the waste line:
- In case of sand or DE filter or a sand filter: Turn off the pump and move the handle on the multiport valve to ‘waste’ mode. Make sure that there is a waste line connected to the waste port and turn the pump back on.
- In case you have a cartridge filter: You will need to open up the ball valve that leads to the waste line. Turn the pump back on after checking waste line is turned to waste port.
- In case you have a hose outlet to cleanse your water: You will have to replace it with a ball valve
- Close the top suction lines: When water is slightly down the skimmer opening, shut of the skimmer suction line to prevent air from entering into the line.
- Check the main drain operation: Check if the diverter valve to the main drain is not blocked. If it is blocked, then you will notice drop in water levels.
- Check local water discharge regulations on how to dump pool water. Drain the water using the built-in pump or by using an external submersible pump and hose. Continuously check the pump and the discharge all through the entire process.
Note : Periodically check to make sure the water is draining properly. Check your pool pump manual for detailed instructions. In case you need assistance in draining your pool water yourself text us and we’ll tell you what you need to do to get you all set.
