lrodptl Posted September 10, 2014 Report Share Posted September 10, 2014 My inground pool has 2 suction ports,one at the skimmer and one a foot below the skimmer. In the past I have drained the pool about 18 inches to blow out that bottom line and plugged it. Is there a more efficient and less costly way? I thought there maybe a plug with a check valve allowing to blow through but not allowing water to flow back in. Thanks. Quote Link to comment Share on other sites More sharing options...
Kimberly Dukes Posted September 12, 2014 Report Share Posted September 12, 2014 Hey Spa, Well I never try this ,I never add antifreeze as i able to disconnect the pipes and allow all the water drain out. I think its easy way and you should also try this one . Quote Link to comment Share on other sites More sharing options...
alexMAT Posted September 12, 2014 Report Share Posted September 12, 2014 Would you consider getting a bypass valve from waterway or who ever and threading that into the ports? you will have to create a plug with check valve. there are check valves available in different sizes for between $30 - $40 Quote Link to comment Share on other sites More sharing options...
