The homeowner in central Austin had been dealing with frustrating low water pressure for a while. Showers weren’t satisfying, filling the tub took too long, and running a faucet in the kitchen meant pressure dropped somewhere else. Radiant Plumbing & Air Conditioning’s Austin plumbing team was called in to evaluate the water pressure and provide options. After testing the system, we installed a new water pressure booster setup and updated key plumbing components so the home would have strong, even pressure throughout.
Job Overview
- Location: Austin, TX
- Client Type: Residential
- Scope: Diagnose low water pressure, install new water pressure booster system, improve backflow protection and piping layout
- Equipment Installed: pressure-boosting pump system with dedicated controls, new backflow assembly, updated valves and insulated piping
- Additional Work (if any): water pressure testing at multiple fixtures, coordination with electrician for pump power, insulation of new piping, system start-up and adjustment
- Why It Mattered: The homeowner wanted consistent water pressure for daily life and to protect their plumbing fixtures from strain caused by uneven pressure.
What We Found
During our visit, we started by asking the homeowner where they noticed the pressure problems the most. They reported weak flow at showers and faucets, especially when more than one tap was open or appliances like the washing machine were running.
We used pressure gauges to check the water pressure where it entered the home and then compared it to the pressure at different fixtures. We found that the incoming pressure from the street was on the low side, and the existing plumbing layout and older valves caused an even bigger drop as water moved through the house. This explained why the home never seemed to get that strong, steady pressure the homeowner wanted.
We also inspected the backflow and piping near the water heaters and main supply line. Some components were older and not set up to support a modern pressure-boosting solution. The home needed an updated, well-planned system to safely increase and control water pressure.
The Solution
To solve the low-pressure issues, our Austin plumbing service team designed a water pressure booster system tailored to this home. We began by shutting off the water, draining the lines, and carefully removing the older valves and piping that were restricting flow.
We then installed a new pressure-boosting pump package with dedicated controls to help raise and maintain steady pressure throughout the house. Along with the booster, we added a new backflow assembly and updated shutoff and check valves, giving the home safer and more reliable protection against backflow. The new piping was laid out to support better flow, then insulated to help protect the lines and reduce heat loss around the water heaters.
Because the booster system required electrical power, we coordinated with a licensed electrician to provide the correct wiring and dedicated circuit for the pumps. Once everything was connected, we turned the water back on and slowly brought the system up to operating pressure. We tested multiple fixtures at once: showers, sinks, and appliances, to make sure the new setup delivered strong, even pressure without spikes or drops. After final adjustments, we walked the homeowner through the new components and how the system would help their home going forward.
Photo Highlights
- During installation, the booster pump was carefully connected to updated piping to ensure strong and consistent water pressure.
. - The new pressure booster and insulated piping work together to deliver steady, dependable water pressure to every fixture.
- The home’s older tankless water heater setup showed inefficient piping and aging components that affected overall water flow.
- A new Rinnai tankless water heater with fresh repiping improved flow, efficiency, and reliability throughout the home.
- The under-sink ReadyHOT dispenser provides instant hot water at the kitchen sink, upgraded alongside the home’s pressure improvements.
The Results
With the new water pressure booster installation in place, this Austin home now has strong, steady water pressure at showers, sinks, and appliances — even when multiple fixtures are running at the same time. The updated backflow assembly and valves make the system safer and easier to service in the future.
Day-to-day tasks like showering, washing dishes, and doing laundry are now faster and more comfortable, and the homeowner no longer has to plan around weak water flow. The boosted and controlled pressure also helps protect plumbing fixtures and piping from the stress of constant pressure changes.
