A Dry Kitchen Sink in Chattanooga

When a Chattanooga homeowner discovered that their kitchen sink shut-off valve would not budge, they found themselves without water throughout the house. After attempts to turn the valve left them stranded, they called HEP for help. Our team quickly learned that although the main shut-off had been closed to prevent flooding, the in-home valve was seized and water pressure was inconsistent.

How the HEP Technician Diagnosed the Issue

Before heading out, the HEP technician asked a few simple questions:

Age of plumbing fixtures and water heater
Any known leaks or past issues with water pressure
Location of the main shut-off and accessibility of your pressure control valve

By confirming that the homeowner had cleared obstructions around the water-heater area in the garage, our technician was able to pinpoint that the home’s pressure-reducing valve (PRV) had worn out over time, leading to a non-functional shut-off under the sink and irregular pressure elsewhere.

Upgrading to a Dual-Chamber Pressure-Reducing Valve

To restore reliable water flow, the old PRV was removed and replaced with a modern ¾" dual-chamber pressure-reducing valve. This upgrade ensures steady pressure throughout the home and makes future maintenance smoother.

After uninstalling the aged device, the HEP technician fitted the new valve onto the main copper line coming out of the concrete slab. Proper sealing and secure mounting kept the new assembly leak-free.

With the fresh valve in place, water was turned back on at the main and inspected under the kitchen sink. Everything flowed perfectly, and the handy dual-chamber design provides extra protection against pressure spikes.

Pro Tips for Homeowners

Locate and label all shut-off valves.
Knowing exactly where your main valve and any secondary shut-offs are can save time during an emergency.
Keep the area clear.
Make sure no boxes, racks, or stored items block access to your water heater and valves. This helps technicians work quickly and safely.
Test your valves annually.
Gently turn each shut-off to confirm it still moves freely. If you feel resistance, schedule a professional check-up.
Consider a dual-chamber PRV.
These valves offer smoother pressure control and can extend the life of plumbing fixtures and appliances.

By staying proactive with valve checks and investing in a quality pressure control upgrade, Chattanooga homeowners can avoid unexpected dry spells and keep their water flowing just as it should. If you ever have questions about your home’s water system, a HEP technician is just a call away.
