Frequently Asked Commercial Plumbing Service Questions

Do you offer residential plumbing services too?

We sure do. DeClue Plumbing handles both residential and commercial plumbing across Greater St. Louis.

Whether you need a toilet repaired, a water heater replaced, or a full pipe replacement in your home, we bring the same honest pricing and reliable workmanship to every job regardless of size.

The best way to know for certain is to have a licensed plumber inspect your system. Commercial plumbing codes in Missouri cover everything from pipe sizing and water pressure requirements to backflow prevention and grease trap installation. If your building has undergone renovations, changed its use, or simply aged without regular inspection, there’s a real chance something is out of compliance. DeClue Plumbing can assess your system and tell you exactly where you stand.

Backflow happens when contaminated water flows backward into your clean water supply, That’s a serious health and safety risk in any commercial setting. Most commercial facilities in St. Louis are required by code to have backflow prevention devices installed and tested annually. If you’re not sure whether your building has the right backflow protection in place, DeClue Plumbing can inspect your system and bring it up to standard.
