Swimming Pool Maintenance Tip by Man About The Pools
Losing Water? Do the cup test:
Fill cup with 3/4 water and mark level and set cup beside the pool.
Mark water level on skimmer frame and let sit for 24 hours.
If water level evaporates at same rate there’s no leak.
If water level in cup drops 1 inch and water level in pool drops 1 1/2 inches, you have a pool leak.
