Why Kitchen Plumbing Deserves Your Attention

Kitchen renovations are super expensive. Just ask anyone who has renovated their kitchen recently. Per the 2025 Cost vs. Value report minor kitchen renovations came in at an average cost of $28,458. Major kitchen renovations were upwards of $82,793.

That's plenty of attention and money being poured into new countertops, flooring and cabinets.

But what about that area behind those new cabinets? Or under that brand-new sink? The plumbing that lies here seems to be rarely considered during or after a kitchen renovation.

The truth is…

All that plumbing works hard in kitchens. Especially garbage disposals. Tubs, faucets and sinks aren't slouches either. These appliances all have plumbing components that can wear out or spring leaks.

Leaks come within a mess with your new kitchen cabinets. Water pools under the sink and ruins the cabinet from the inside out. Worse, cabinets have to be taken off to fix these kinds of leaks. Destroying the aesthetics of even newer kitchens.

This is why using a professional garbage disposal replacement service when installing or maintaining your kitchen disposal helps. Boris Mechanical can ensure all plumbing connections are tight and the disposal is running properly.

Helping you avoid any leaks down the road.

Signs It's Time For a Garbage Disposal Replacement

Garbage disposals are nasty. They're fed food waste every single day. Which means your disposal is taking a beating everyday too.

While a garbage disposal can last long when properly maintained they do need to be replaced. According to the International Association of Certified Home Inspectors most disposals last around 12 years before needing replacement.

Heavy use and poor maintenance shorten this lifespan significantly.

Look out for these signs. It's time to say goodbye to your garbage disposal.

• If you find yourself constantly having to hit the reset button, it's time to invest in a new garbage disposal.

• Grinding or rattling noises when the unit is on means it's dying.

• Leak pooling underneath from the unit is another solid sign.

• If water backs up in the sink when using your disposal, the blades have likely dulled down.

• Smells that won't go away even with regular cleaning come from food particles trapped in areas you can't reach.

If your garbage disposal is older than 10 years and experiencing multiple signs from above, just replace it. It'll save you money in the long run. Plus, you'll protect your surrounding plumbing from any serious damage caused by an old unit.

Like water damage.

How Water Damage Destroys Kitchen Renovations

Water damage is every homeowner's nightmare. And for kitchen renovations, it can undo all your hard work pretty quick.

Little do most homeowners know that water damage and freezing is responsible for about 22.6% of all home insurance claims. That comes to an average of $15,400 per claim. (Data from Insurance Information Institute via This Old House)

Kitchens are a leading cause for these claims.

Every appliance you have in there is connected to a waterline. Dishwasher, sink, ice maker on the fridge. You get the point. Every connection is a potential kitchen nightmare.

Once water damage starts, it's difficult to know the extent of damage. Water weasels its way into places you can't see immediately.

Behind walls, underneath floors and inside cabinetry are death sentences for kitchen renovations.

You can hide water damage for a while by wiping up spills and running fans. But as soon as you start remodeling that kitchen you'll see the damage done behind the scenes.

That's why plumbing maintenance is key.

Plumbing Maintenance Tips That Actually Work

Maintenance is the best renovation protection. Here are some effective tips to keep your kitchen plumbing in working order.

Always Run Cold Water When Using Your Garbage Disposal

Cold water should be running when you turn on your garbage disposal and while it's grinding food scraps up. Cold water solidifies grease and fats so the blades can do their job.

Hot water liquefies everything making it harder for your disposal to grind up food.

Take 30 Seconds to Check Under Kitchen Sink Monthly

Once a month take 30 seconds to peek under your kitchen sink and look for any leaks or discoloration. If you spot it early, you can fix it before any real damage is done.

Don't Overload Your Garbage Disposal

Your garbage disposal isn't a garbage can. It cannot handle tons of food at once either. Feed your disposal food scraps slowly and avoid putting bones, coffee grounds, and starchy vegetables down your disposal.

Have Your Plumbing Professionally Inspected Once a Year

Once a year have a qualified plumber come check out the state of your kitchen's plumbing. Licensed plumbers can check connections, pressure and overall functionality. They can often find issues you would never know existed and prevent burst pipes.

Replace Old Supply Lines

Supply lines don't last forever. Worst case they should be replaced every 5 years. Ideally, every time you install a new kitchen you should replace the supply lines that attach to the dishwasher and faucet.

Waterlines under pressure can burst at any time. Be sure to use those replaced lines to your advantage.

The Bottom Line

Kitchen renovations don't happen everyday. For most homeowners it's a huge project that costs thousands. Don't let that plumbing ruin all your hard work.

By staying on top of maintenance, replacing that aged garbage disposal and tackling small problems head on. You can save yourself:

• Time. Nobody has time to deal with cleanup and repairs.

• Money. Small issues are way cheaper to repair.

• Stress. Peace of mind, your kitchen is functioning as it should.
