How To Use Water Blocks

After winterizing your pool and placing your winter pool cover, you need to properly secure the cover. One of the best ways to do so are Doheny’s Water Blocks.

  1. Start by placing unfilled Doheny’s Water Blocks around edge of pool.
  2. Slide the blocks through the loops on your pool cover to secure them.
  3. Begin filling your Doheny’s Water Blocks. Only fill each block 1/2 to 3/4's of the way full. This allows for freeze expansion.
  4. Make sure to put the lid on each water block when finished filling.
