I've needed Southside three times in the past two years...for a new water heater (they had the best price), a new shut off valve for my sprinklers, and most recently to fix a phantom noise in one of my toilets. After nearly three hours of troubleshooting, Kyle was able to find a small plastic/ceramic thing was stuck in the water line and remove it. Problem solved. Would use these guys again in a heartbeat.













My wife and I decided on moving forward with a new Navien tankless water heater and a Halo whole house water filtration system.
Mark, Adam, Trevor, and Isaiah performed with excellence to remove the old tank and install the new systems all within a day.
We have been enjoying the improved water quality and endless hot water with the new systems.
I highly recommend trusting Southside Plumbing with all of your plumbing needs!
FAQs for Centennial, CO Homeowners
Older Centennial homes often have galvanized steel supply pipes that corrode internally over time, restricting water flow. Other causes include a failing pressure reducing valve or mineral buildup. Our team can diagnose the issue and recommend the most cost-effective solution, whether that’s a valve replacement or a section repipe.
We recommend annual maintenance for tank water heaters. This includes flushing sediment, checking the anode rod, inspecting the temperature and pressure relief valve, and verifying gas connections. Regular maintenance extends the life of your unit and keeps it running efficiently.
Yes. Our service area covers West Centennial and extends to surrounding communities including Foxfield. We’re familiar with the properties in that area and the plumbing challenges they present.
If you’ve noticed moisture, dampness, or musty odors in your basement — especially after heavy rain or spring snowmelt — a sump pump can protect your home from water damage. We can assess your situation and recommend the right system for your needs.
Tankless water heaters provide on-demand hot water, take up less space, and are more energy-efficient than tank systems. For larger homes or households with high hot water demand, the long-term savings and convenience often make the upgrade worthwhile. We can help you evaluate whether it’s the right fit.
