Drain pipes will often last 50 to 80 years, depending on the material, before they require replacement. It's more likely to replace a pipe due to damage than wear. Extreme heat and cold can cause damage to pipes, and even rodents will try to chew through them if they're desperate for water.

How To Tell If Sink Drain Is Leaking?

Check the area under the sink for moisture or puddling that may have originated from the drain. Run water into the sink bowl or bowls and watch to see if you notice any dripping. You can use paper towels and dab around the drain to find any possible slow leaks that aren't easy to notice.

What To Do If Sink Drain Is Leaking?

If you have a leak in your kitchen sink drain, you'll want to shut off the supply line to the kitchen sink to prevent anyone from using it. Start by locating the leak and determining whether you need to replace any parts. If you have some plumbing tools laying around, you can try tightening up the pieces of the drain to see if that helps, but avoid over-tightening anything.

Does A Kitchen Sink Need A Vent?

Yes, a kitchen sink does need a vent, but this is often tied into your whole home drainage system and is typically connected to the main sewage line rather than the sink's direct drain system. If your sink is fairly far away from the waste vent, you may need to look at under the sink options. A professional plumber will be able to help you decide where to place a vent in your system.

What Does a Vent Do?

In plumbing, a vent relieves the pressure built up by the draining water. It allows air to enter and escape the drainage system, preventing buildup and helping the traps in your plumbing to expel the sewage gasses outdoors. Without proper venting in your drainage system, your water will drain slowly, and drains will release strong sewage odors.

Do You Have To Replace A Clogged Drain?

Plumbers are equipped to deal with the most serious clogs and have special equipment like drain cameras and power augers to access and remove deep, stubborn clogs.
