Preventative Well Pressure Tank Maintenance in San Marcos, CA
While our primary service is well pressure tank replacement, FKM Plumbing also emphasizes the importance of preventative maintenance for your well system in San Marcos, CA. Regular checks of your pressure tank's air charge and overall condition can help identify potential issues before they lead to a complete failure. During a maintenance visit, we can top off the air charge, inspect for early signs of corrosion or leaks, and advise on steps to maximize the lifespan of your current tank, potentially delaying the need for replacement.
Tank Tee, Gauge and Relief Valve Replacement in San Marcos
The tank tee is the manifold that connects the tank, switch, gauge, relief valve and drain. Galvanized tees corrode and choke flow, especially with sandy or mineral-heavy water. We replace them with brass or stainless steel tank tees that hold up much longer. A new liquid-filled gauge gives accurate readings, and a fresh relief valve protects against a stuck switch. These small parts make a big difference in reliability.

Constant Pressure System Conversion in San Marcos, CA
A constant pressure system pairs a variable speed drive like the Franklin SubDrive or Grundfos SQE with a smaller pressure tank. The pump speeds up or slows down to hold a set pressure, so showers do not fade when a sprinkler kicks on. These systems cost more, often $2,500 to $5,000, but they eliminate pressure swings. They also reduce hard starts on the motor. We explain whether your well and pump are good candidates.

Frequently Asked Questions About Well Pressure Tank Replacement in San Marcos
Most well pressure tank replacements cost $900 to $2,200 installed, depending on tank size and whether the switch and tank tee are replaced. Large capacity or multi-tank setups can run $2,500 or more. We give a firm price before starting.
It depends on your pump's flow rate and the drawdown needed for at least a one minute run time. We calculate this on site instead of going by the old tank.
While it might seem like a DIY project, well pressure tank replacement involves working with pressurized water, electrical components, and ensuring proper sizing and calibration. It is strongly recommended to hire a professional plumber to ensure safety, code compliance, and proper system function.
Most pressure tank replacements take two to four hours. Adding a constant pressure system or multiple tanks can take the better part of a day.
In most areas, a permit is not typically required for a like-for-like well pressure tank replacement. However, if there are significant changes to the well system or its location, a permit might be necessary. We will advise you on any permitting requirements for your specific situation in San Marcos.
Common signs include your well pump repeatedly turning on and off (short cycling), fluctuating water pressure, air sputtering from faucets, or a tank that is waterlogged (feels heavy when tapped and full of water). If you notice any of these, it is time for an inspection by a pro.
A typical well pressure tank replacement generally takes between 2 to 4 hours. This includes disconnecting the old tank, installing the new one, and testing the system to ensure proper operation and pressure settings.
We install a variety of proven well pressure tank brands, including Well-Rite, Flex-Lite, Amtrol, and Goulds. Our technicians can recommend the best brand and model for your specific well system and budget.
