Listen for excessive pump noise as a warning of possible problems in that area. Today's newer pumps are sealed units that don't require any maintenance, but rubber or composition pump seals can go bad and result in bearing failure or electrical shorts. Replace any pump that's more than 7 or 8 years old and is in need of repair. Keep a close eye on the pressure gauge. An inoperative pressure gauge means you can't tell when water pressure begins to build from the normal levels indicated by a clean, efficient filter and the higher pressure of a filter in need of cleaning.
High pressure means unnecessary strain on the pool pump and a less efficient filtering system.
Instead of the chlorinated shocker, a solution of 27 percent hydrogen peroxide is used to shock the pool. Inc. How things get done. Use of this Web site constitutes acceptance of the eHow Terms of Use and Privacy .
