Summit Water Services many Second / Vacation / Rental homes. If your home is to be left unattended for an extended period we recommend shutting off the water coming into the home. This can prevent possible damage and save money in the event of a leak. In winter months heat must be maintained above 55 degrees to prevent frozen pipes. During the irrigation season we highly recommend having water use tracked. Most irrigating occurs at night and many leaks go unnoticed. Tracking water use can catch these leaks early, saving you money.
