Plumbing Guides for Los Gatos Homeowners

Short, practical guides on the plumbing problems Los Gatos homes run into. Read them to decide what you can handle yourself and when to call a plumber.

What you will find in these guides

Each guide starts with the answer, then explains why, what you can safely check, and when to stop and call. We write about water heaters, drains, sewer backups, toilets, water softeners and new construction, because each one involves a decision a homeowner has to make.

The guides use local facts where they apply. That includes water hardness figures from San Jose Water, sewer lateral ownership under West Valley Sanitation District, and permit steps from the Town of Los Gatos.

How we keep guides accurate

General plumbing advice is written plainly and cautiously. Local statements come from the utility or town pages that publish them. If a number is not published, we tell you to test your tap or ask the utility instead of guessing.

We do not print prices, because the cost of a job depends on access, materials, pipe length and permits. Guides that cover cost explain the factors so you can read a quote with confidence.

Topics the guides cover

Water heater guides cover common faults, flushing a tankless unit in hard water, exhaust leaks on gas tanks and what a gas valve repair involves. Drain guides explain what vinegar and baking soda can and cannot do, and why toilet paper sometimes clogs a line that looks fine.

Sewer guides focus on who fixes which pipe after a backup. Fixture guides walk through a toilet fill valve step by step, and the installation guides cover PVC fittings, new construction rough-in and softener salt.

A short routine that prevents calls

Twice a year, check under every sink and behind every toilet for damp spots. Run each tap for about a minute to clear stale water, and look at the shutoff valve on each fixture to make sure it still turns. A valve that is stuck today will fail you during an emergency.

Find your main water shutoff and your sewer cleanout before you need them. Write down where each one is, and tell everyone in the house. That alone saves minutes when water is moving.

When a guide is not enough

Some problems should not wait for reading. If water is flowing, shut off the main valve, which usually turns clockwise, and call (855) 575-2890. If you smell gas, leave the building, call 911 from outside, and then call the gas utility before any plumber.

For a sewer backup, stop using water and call the sanitation district first. Our services page lists the repairs we handle when the district's work ends and a plumber is needed.
