What's Wrong with this Picture: Swollen Water Supply Line

ANSWER: Swollen Water Supply Line In Need of Repair

The above picture was taken on one of my Massachusetts inspections. It’s not uncommon to find swollen water supply lines in those parts of the country that experience freezing temperatures. However, it’s only when the line bursts that the average homeowner becomes aware of the situation. Then it becomes an insurance claim and possibly major damage to the home.

This line is connected to a hose faucet or sprinkler system valve at the exterior of the home. The swelling is the result of improper winterization of the sprinkler system or a garden hose left connected to the hose bib. Residual water in the supply line froze and expanded, swelling the pipe to its current near-bursting dimensions. The water supply valve pictured above needs to be turned off prior to the first freeze and residual water drained from the line running to the exterior. This particular supply line is defective in its current state and needs to be repaired.

Always ensure all your outside water sources are properly prepared for the coming winter season. This is a simple task, but can have huge consequences if ignored.
