Well Pressure Tank Replacement Done Right in Sonoma

New Reliance pre-charged well pressure tank on its stand, piped up with a pressure gauge fitted

What was replaced?

A corroded, leaking well pressure tank at a home in Sonoma, swapped for a 52-gallon tank before the failure took the pump with it.

What does the pressure tank do?

It holds pressurised water so the pump does not start every time a tap opens. It is working constantly in the background whether anyone notices it or not.

What happens if it fails?

The pump cycles far more often than it should, which leads to premature pump failure, inconsistent pressure, and a considerably more expensive repair.

What was wrong with the well pressure tank?

This one was a classic case of catching a problem before it turned into a much bigger headache. A homeowner in Sonoma had a corroded, leaking well pressure tank that was compromising their whole water system. Left alone, that kind of issue doesn't stay small for long. We swapped out the old tank and installed a new 52-gallon Reliance pre-charged pressure tank. The pressure gauge you can see plumbed into the line lets us - and the homeowner - keep a close eye on system performance going forward.

What does a well pressure tank actually do?

Clean connections, solid setup. Here's the thing about well pressure tanks that a lot of people don't realize: they're doing constant work behind the scenes. Every time you turn on a faucet, flush a toilet, or run the dishwasher, that tank is regulating the pressure so your well pump doesn't have to cycle on and off nonstop. When the tank starts failing - whether from corrosion, a ruptured bladder, or a slow leak - your pump takes the hit.

Why does tank size matter?

That leads to premature pump failure, inconsistent water pressure, and eventually a much more expensive repair. A 52-gallon tank is a solid size for a residential well system. It gives the pump enough buffer to run efficiently without short-cycling. And going with a pre-charged tank means the air pressure is already set at the factory, so we're working with a reliable baseline right from the start.

What are the signs your tank is failing?

Well systems are their own world compared to city water. If your water pressure feels off, your pump is running constantly, or you're noticing any moisture around your existing tank, those are all signs worth paying attention to sooner rather than later.

How do I know if my well pump is failing?

Common signs are pressure that fluctuates or drops away during use, the pump cycling rapidly on and off, air spitting from taps, sediment appearing in the water, or the pump running continuously without building pressure. Rapid cycling frequently points at the pressure tank rather than the pump itself — a waterlogged tank makes a healthy pump behave like a failing one.

What are the septic rules in Sonoma County?

Sonoma County requires a valid operational permit for any nonstandard system, and for a standard system where monitoring was made a condition of approval, issued for one, two or three years depending on the system. Operating a system that requires a permit without one is treated by the county as a public nuisance. Separately, systems inside the Russian River pathogen boundary need a basic operational inspection every five years.
