  • “The best plumber in town! GAC came to my attention by word of mouth. The very next day one of my ballast boxes went out in my store & I called them.

    Gary came out almost immediately. He was prepared to go to work right away. He even had disposable booties that he slipped on over his boots to protect the carpeting in my store! A+ grade from me!"”

    Also, he offered a lot of insight on how the hot water heaters operate. He did not take any shortcuts to complete the job. Cost of the job was very reasonable!! I HIGHLY RECOMMEND GAC when needing a plumber!!!”

The Most Common Plumbing Issues:

Winter can be an especially tough season when it comes to your home’s plumbing system. Cold temperatures threaten to freeze pipes and holiday gatherings can put extra stress on your dishwasher, food disposal and drain systems. The following tips will help you avoid some of the most common winter plumbing problems:

Frozen Pipes

Exposed water pipes in an unheated basement or garage often face the risk of freezing in winter. These pipes can be insulated by installing foam pipe sleeves. In extremely cold areas, adding an electric heat tape to vulnerable pipes is a good idea as well. You should also disconnect garden hoses, turn off and drain the exterior line, if possible. Inside your home, open cabinet doors that are near plumbing lines to allow heat to circulate. You can also slightly open each faucet to keep water moving. Frozen Pipe Information

Clogged Drains

While working in the kitchen, NEVER wash oil down the drain, as it can congeal in cold temperatures and create a clog. Another good idea is to make sure you rinse your dishes before loading the dishwasher. You might also want to rinse your food disposal with warm water for thirty seconds before and after each use. In the bathroom, avoid flushing anything but septic-safe paper down the toilet. Also, keep the drains in your sink and shower free of hair and other debris.

Sump Pump Backups

Keep your sump pump pit free of all debris, including ice, that may lead to clogs. Also, you’ll want to make sure the discharge area is clear.
