What is pump & well repairs and when do you need it?
Pump and well repairs cover the equipment that gets water from a private well into your house — the pump itself, the pressure tank, and the pressure switch. Avanté Plumbing services all three across rural Sonoma and Marin County under California CSLB licence #841938. Six symptoms account for most calls: the pump switching on and off every few seconds, water pressure that sags or disappears, air spitting from the taps, cloudy or sandy water, a pump running constantly, and an electricity bill climbing for no obvious reason. The most common single cause is a failed bladder inside the pressure tank, which makes the pump cycle rapidly and wears it out long before its time — and it is repairable if caught early. Outside the city limits, particularly west of Sebastopol and across the Santa Rosa Plain, private wells are common and so is this failure.
How do I know if my well pump needs repair?
Some of the most common signs are low water pressure, no water at all, sputtering faucets, dirty water, air in the lines, or a pump that runs nonstop. You may also notice your system turning on and off too often. If you see any of these problems, call us. At Avante Plumbing, we can inspect your well pump system, find the cause, and explain the repair clearly before any work begins.
Can you fix low water pressure in a well system?
Yes. Low water pressure can come from several issues, including a failing well pump, pressure tank problems, clogged pipes, bad pressure switches, or leaks in the system. We don’t guess. We test the system, pinpoint the problem, and make the right repair so your water pressure is steady and dependable again.
Do I need a repair or a full well pump replacement?
Not always. Many well pump issues can be repaired if caught early. We will always look for the most practical and cost-effective option first. If the pump is badly worn, outdated, or not worth repairing, we will let you know honestly and explain your replacement options. Our goal is quality service at a reasonable price, not pushing work you do not need.

We work on many common residential well and water pump problems. If your system is losing pressure, turning on and off too often, failing to prime, or struggling to keep up with normal household use, we can diagnose the issue and make the needed repair. Our team handles problems involving well pumps, pressure tanks, pressure switches, check valves, fittings, piping, electrical connections, and other key parts of the water supply system. We also help troubleshoot issues that may be tied to sediment buildup, worn components, leaks, air in the lines, or faulty controls.
A well system has several parts that must work together to deliver steady water pressure. The pump moves water from the well to your home. The pressure tank helps regulate flow and reduces wear on the pump. The pressure switch tells the system when to turn on and off. If even one part starts to fail, you may notice weak pressure, sputtering faucets, inconsistent water flow, or no water service at all. Our job is to find the real cause of the problem and fix it the right way, not guess and hope for the best.
We start with a careful inspection of the system and a clear conversation with you about what has been happening. We look at the symptoms, check the pump operation, inspect the pressure tank and switch, review visible plumbing connections, and test system performance when needed. Once we identify the issue, we explain what we found in plain language and recommend the most practical repair options. We believe customers should know what is wrong, why it matters, and what it will take to get the system working again.
Depending on the problem, repairs may include replacing a failed pressure switch, repairing damaged water lines, correcting leaks, replacing worn fittings or valves, addressing pressure tank issues, or resolving pump performance problems. In some cases, a pump may be repaired. In others, replacement may be the more cost-effective choice if the equipment is badly worn or unreliable. We will always walk you through the options so you can make an informed decision for your home and budget.

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.
Does the Russian River septic rule apply to my property?
It applies parcel by parcel, not by town. The North Coast Water Board's Russian River Pathogen TMDL Action Plan sets a boundary generally covering parcels within 600 feet of the Russian River and mapped tributaries including Dutch Bill Creek, Green Valley Creek, Dry Creek, Santa Rosa Creek, Mark West Creek and the Laguna de Santa Rosa. The controlling map and Permit Sonoma's programme decide it for a given address.
