There are a few thing that can cause water to “pond” on your mesh cover.
Springs should be compressed 50-75% around the cover. Properly compressing the springs will tighten the cover and may resolve the issue. Improperly installed, sagging covers may pond water and could void your warranty if damage occurs. Keeping your cover taut with properly compressed springs will also protect the longevity of your cover.
Sometimes the mesh material we use on our covers has a waxy residue left over from our suppliers’ manufacturing process. That’s a normal occurrence and can take 1-2 seasons to break down. The water will continue to drain, it may just drain a little more slowly than normal.
RuggedMesh covers drain more slowly than MeycoLite covers and sometimes require winter maintenance due to their tighter weave –  especially if there is a lot of rain. The tighter weave on a RuggedMesh cover filters our finer particles in the water as it passes through.  If water continues to sit on the surface of your RuggedMesh cover, check the springs to be sure they are compressed properly.
