San Marcos Plumbers You Can Trust, Seven Days a Week

Your San Marcos Plumbing Visit, Step by Step

Here’s how a visit goes, from your first call to the finished repair.

1. Tell us what’s happening. Describe the problem by phone or online, and we’ll book the soonest visit we can.
2. See what we find. Our technician listens first, then finds the cause and shows you what it is. That might be a worn part under the sink or camera footage from inside your sewer line.
3. Choose what happens next. Every option comes with its price, and we’ll flag anything that isn’t urgent. The estimate is free, and we start once you’ve chosen.

Call to Set Up Your Visit

San Marcos Plumbing Services, Big Jobs and Small

We handle repairs, drains, sewer and water lines, water heaters, and repiping for San Marcos homes and businesses. A single dripping faucet is as welcome a call as a new water line.

Plumbing Repair in San Marcos, From Dripping Faucets to Failed Valves

Everyday plumbing repair is a big part of what we do. That might be a disposal that hums but won’t spin, a tub spout that keeps dripping after you shut it off, or a toilet that keeps refilling. Planning a new vanity or a kitchen update? We install fixtures and handle plumbing for kitchen and bathroom remodels, too.

Our technician fixes the part that failed. If the valve or supply line next to it looks worn, too, we’ll point it out, and you can add it now or wait.

Clearing Clogged and Slow Drains

Kitchen sink draining slowly, or a toilet that clogs every week? Grease, food scraps, hair, soap, and wipes cause most clogs. Our San Marcos drain services start with finding where the clog sits. When one drain clogs again and again, the trouble is often in the pipe itself, so a camera look can be worth it before clearing it again.

Hydro Jetting for Drains That Keep Slowing Down

Grease and soap film coat a pipe’s walls over time. A snake opens a path through the clog, but it can leave that coating behind, so the drain may slow again within weeks.

Hydro jetting scours the walls clean with high-pressure water, after a camera check confirms the pipe can take it.

Sewer Lateral Repair in San Marcos

Gurgling toilets, water coming up in the shower when the washer drains, or a sewage smell in the yard can point to the sewer lateral. That’s the pipe that carries everything from your house to the main line. If Vallecitos Water District serves your home, that pipe is yours to maintain, as the district explains.

You’ll watch the camera footage with our technician and see the roots, crack, or sag for yourself. Depending on what turns up, the fix might be a cleaning, a sewer line repair on one section, or a new lateral, with as little digging as the job allows.

Main Water Line Leaks and Replacement

The main water line runs from the meter box into your house, and if Vallecitos serves your home, it’s yours to maintain, too. A leak on it usually hides underground, so watch for:

• A water bill well above last year’s for the same months
• A spot in the yard that stays muddy days after the sprinklers shut off
• The sound of running water near the meter box when nothing inside is on

We narrow down the leak before anyone digs. Then we’ll price a water line repair at that spot and a full replacement side by side.

“Chris & Jacob were polite, professional, and provided us with various no pressure options to choose from in deciding what route to go. And we appreciate their honest evaluation of our leak issue.” —Manny G.

Have Your Water Line Checked

Water Heaters, Tank or Tankless

Lukewarm showers, popping sounds from the tank, or water around its base are good reasons to have it looked at. We repair and replace water heaters, and we’re certified by both Navien and Rinnai to install their tankless water heaters. Popping often means sediment has settled in the tank, and a flush may be all it needs. A worn part, like a thermostat or a heating element, can be a simple repair, and we’ll tell you if yours is worth fixing.

Slab Leak Detection and Whole-House Repiping

A warm patch of tile, or a water bill that jumps with no leak in sight, can mean a slab leak under the foundation. Electronic leak detection helps us find it before we suggest cutting into anything. One leak can often be repaired on its own. A reroute or whole-house repipe comes up only when leaks keep recurring.

We work on septic systems, too.

Plumbing Care for San Marcos Homes of Every Age

Most San Marcos homes were built from the 1970s on, and many went up after 1990. We work all over the city, from Richland and Richmar to Santa Fe Hills, Twin Oaks Valley, Barham/Discovery, and Lake San Marcos.

Whether your house was built in the ’80s or the 2000s, the water heater, the shutoff valves under the sinks, and the parts inside each toilet may still be original. Those parts wear out with use, and a quick look can tell you which ones are wearing thin.

Easy checks for any San Marcos home:

• Find the sewer cleanout in your yard, often a capped pipe near the house, so a plumber can reach the lateral without coming inside
• Look under sinks a few times a year for drips or a damp cabinet floor
• Keep grease, wipes, and food scraps out of the drains
• Have the sewer lateral checked with a camera if several drains start to slow

Your San Marcos Plumbing Questions, Answered

How do I stop a leak until you get here?

Turn off the valve under the fixture if there is one. If water is still coming, close the main shutoff at the house. Then call (951) 678-3275 and describe what you see, even if you have no idea where it’s coming from.

Can you give me a price over the phone?

Not an accurate one, but the estimate at your home is free, with no obligation to book the work. A slow drain might be a clog in the trap or a problem in the sewer lateral, and those are priced very differently. You’ll see the price for each option before you decide.

Does a high water bill mean I have a leak?

Not always, but it’s worth checking. Turn off all faucets and appliances, then check your water meter. If it’s still moving, water is going somewhere. A toilet that keeps refilling can waste water around the clock, and a leak on the main water line or under the slab can hide for months. We’ll find which one it is.

Can you find a leak I can’t see?

Often, yes. Our technicians use pressure testing and electronic leak detection to narrow down a hidden leak in a wall, under the slab, or in the yard. That keeps any opening we make as small as possible.

How soon can a plumber come out?

Usually the same day. We schedule plumbing visits seven days a week, Saturdays and Sundays included. Call (951) 678-3275, and we’ll get you the first opening we have.

Can a San Marcos business book you, too?

Yes. Shops, offices, and other San Marcos businesses can book us for commercial plumbing, from restroom fixtures to water heaters and backed-up drains. Tell us your business hours, and we’ll do our best to plan the visit around them.
