A full house for the holidays can be wonderful–but not for your plumbing. Extra pressure is put on home plumbing systems during the holidays, with day-long meal prep and additional house guests, it’s easy for the wrong items to go down the drain and disposal. Below are their top tips for dodging drain disasters.

Your sink can’t handle everything. Fats, bones and vegetable peels can clog drains and damage the disposal. When fats and grease cool, put them into a disposable container and throw it in the trash. If you have a compost pile, that’s a good place for peels. Anything that you can hold in your hand, throw it out instead.

Holiday cooking can strain your garbage disposal. Know how to properly use it! Always run the water when using a garbage disposal. If your disposal becomes clogged, turn it off, and shut off the water. Don’t reach into a disposal, and never, ever use harsh chemicals to treat a clog. Like other kitchen appliances, disposals can use tune-ups, too.

Think outside of the kitchen. Be mindful of the plumbing use in other areas of the home. Holidays guests can require more loads of laundry. Poor water quality and age can lead to breakdowns in the washer hose, which can lead to massive water leaks. Getting your hose inspected will save you from water damage from a defective hose.

Avoid the messiest of all plumbing disasters by understanding what can and cannot be flushed. The amount of people in a normal household easily triples during the holidays. ┬áThis means triple the amount of trips to the bathroom, which strains the integrity of your home’s plumbing system. Remind your guests what can and can’t be flushed, and inform them of any plumbing issues you are already aware of. Meaning, if you need to jiggle the toilet handle to get it to flush, spread the word.

Preventative maintenance can save you a holiday headache. If it’s been a while since you’ve had a plumbing inspection, now may be a good time to call a trusted plumbing professional. They can spot potential trouble areas and prepare your home for the holiday influx. They can also help winterize your plumbing system for the colder weather to come. Cold temperatures can put more stress on your pipes, drains, outdoor hose bibs and water heaters.
