Summary:

Mr. Rooter Plumbing® provides helpful information on plumbing in crawl spaces:

  • Crawl spaces, unlike basements or slab foundations, are narrow areas under floors that house plumbing and wiring, and they require specific maintenance to avoid common issues.
  • Frequent problems include wet crawl spaces, leaks or burst pipes, poor drainage, condensation, aging pipes, and frozen pipes, all of which can lead to structural damage, pests, or water damage.
  • Wet crawl spaces may result from groundwater, leaks, poor grading, or drainage failures; addressing them promptly helps prevent mold, mildew, and pest infestations.
  • Preventive maintenance includes seasonal plumbing inspections, insulating pipes to prevent freezing, and upgrading drainage systems (e.g., French drains or sump pumps).
  • Licensed plumbers, such as those from Mr. Rooter Plumbing®, offer repairs, inspections, insulation, and drainage upgrades to keep crawl space plumbing in good condition year-round.

Have you given much thought to what’s underneath your home? You either have a basement or a crawl space, and the type of space you have can determine how you manage your home’s plumbing!

While not as common as concrete slab foundations, crawl spaces are still a reasonably common foundation type in the United States. They describe an unoccupied, narrow space under a floor or in the roof to provide access to wiring and plumbing. If you want to take good care of your plumbing system to keep it functioning at its best, keep reading for helpful tips and information on crawl space plumbing.

Common Crawl Space Plumbing Issues

Awareness of common crawl space plumbing issues can put you in good standing to manage plumbing problems as they arise or stop them from happening in the first place.

Wet Crawl Space

A wet crawl space may not seem like a big deal because the water isn’t inside your home. It’s also true that a small amount of water in crawl spaces, especially after heavy rain, is quite common.

However, if your crawl space is always wet, this can be problematic. Standing water can cause structural damage and attract pests like rodents and termites. It can also lead to mold and mildew growth that has the potential to affect your indoor air quality.

Many things can cause wet crawl spaces, such as groundwater, plumbing leaks, foundation issues, and poor grading. If you have a wet crawl space, contact a trusted plumber in your area for advice.

Leaks and Burst Pipes

If you notice damp spots and puddles around your home, check your crawl space for a leaking or burst pipe. Supply and drain lines can start leaking or burst due to damage, corrosion, and age. The good news is that licensed and insured plumbers can repair and replace old and damaged pipes in your crawl space.

Drainage Problems

Water pooling around a crawl space or seeping into it can be an issue that’s important to address. As mentioned, a damp crawl space is a hot spot for pests and can also increase the risk of structural damage.

Drainage issues can be caused by damaged or poorly designed underground drains, clogged drains, and insufficient slopes. If you suspect drainage issues in your crawl space, contact a trusted plumber. They can suggest and implement solutions like French drains and other drainage systems.

Condensation

If you live in a humid climate, there’s a chance you’ll be dealing with condensation. Condensation can form on cold water pipes, resulting in dripping water and water accumulation.

Old Plumbing

Even with the best plumbing systems and drainage methods, no pipes last forever. If you have old pipes in your crawl space, they can eventually start leaking or fail altogether.

Frozen Pipes

While your pipes aren’t directly exposed to the elements in your crawl space, they are still exposed to cold temperatures. When those temperatures drop below freezing, your pipes can freeze! Frozen pipes can be at risk of bursting, causing serious property damage!

If you’re wondering how to keep pipes from freezing in crawl spaces, it can be as easy as insulating them to protect them from the elements.

How to Maintain Your Crawl Space Plumbing

In the same way that you would maintain the pipes and plumbing system in your basement or concrete slab, you can do the same for your crawl space. Doing so puts you in a strong position to avoid a plumbing emergency!

Perform Seasonal Plumbing Checks

You don’t have to wait until your crawl space plumbing encounters an issue before requesting help. You can contact a plumber to perform a seasonal check-up. For example, a plumber can check your pipes before the colder weather sets in to look for any noticeable cracks or signs of damage that might cause them to freeze, burst, or start leaking.

Install Insulation

Frozen pipes aren’t just inconvenient; they can also be damaging. Frozen pipes can burst, leading to water damage and, sometimes, even structural damage. Protect your pipes and property in the winter months to come by insulating them.

Plumbers offer this service, but you can also insulate pipes yourself with rigid foam, flexible elastomeric foam or rubber, or polyethylene.

Upgrade Your Drainage System

If you’re dealing with water in your crawl space due to poor drainage, upgrade your drainage system. Talk to your local experienced plumber about a French drain or sump pump.
