Every Masters Plumbing Service technician working in San Marcos is background-checked before hire, uniformed, and arrives in a marked vehicle. You know who's coming and you can verify their credentials. That's the standard we hold ourselves to — not because it's legally required, but because it's what we'd want if we were the customer.

Warning Signs
When to Stop Waiting and Call a Plumber in San Marcos
Most plumbing problems give warning signs before they become expensive disasters. Here's what San Marcos homeowners should watch for — and why waiting makes every one of them worse.
01
Slow Drains Throughout the House
When two or more drains run slow simultaneously in your San Marcos home, the blockage is almost always in the main line, not individual fixture traps.
02
Water Bill Spike With No Explanation
Hidden supply line leaks in San Marcos homes waste thousands of gallons before they surface. A meter check with all fixtures off confirms whether water is escaping.
03
Discolored or Rusty Hot Water
Brown or rust-colored hot water is almost always a water heater with a depleted anode rod or internal corrosion — both signs the unit is approaching failure.
04
Low Water Pressure at Multiple Fixtures
If your San Marcos home's water pressure has dropped noticeably across the whole house, the issue is upstream — likely the PRV (pressure reducing valve), the main supply line, or corroded galvanized pipe narrowing the interior.
05
Running Toilet That Won't Stop
The sound of water running in the tank between flushes is a flapper or fill valve issue. Neither is expensive to fix, but both compound into significant water costs if ignored.
06
Wet Spots or Stains on Ceilings and Walls
Moisture stains on ceilings or walls that reappear after painting point to an active supply or drain line leak inside the structure. The visible damage is usually much smaller than the wet zone inside the wall.
07
Gurgling Sounds in Drains or Toilets
Gurgling when a toilet is flushed, or when the washing machine drains, points to a venting issue or a partial main line blockage. Air displaced by water flow has nowhere to go and creates the gurgling sound.
What Masters Plumbing Service Handles in San Marcos
Here's a look at what our San Marcos, TX-licensed plumbers do every day — and why the depth of our service offering means you call one company instead of tracking down three.
Emergency Response
24/7 Emergency Plumbing in San Marcos, TX
Plumbing emergencies don't schedule themselves around business hours. A burst pipe, overflowing toilet, sewer backup, or failed water heater at midnight needs the same licensed response as one at noon — and Masters Plumbing Service provides it. Our emergency dispatch team operates around the clock, 365 days a year, with technicians staged to reach San Marcos addresses in 30–60 minutes.
Burst supply line response — shut-off, repair, pressure test

Sewer & Drain Systems
San Marcos Sewer & Drain Specialists
Sewer line failures are the most consequential plumbing problem a property in San Marcos, TX can face — and the most misdiagnosed. A sewer line that clears with a cable but backs up in 6 weeks isn't a clogging problem; it's a structural problem that clearing can't fix. Masters Plumbing Service's sewer crew runs a CCTV camera into every sewer line before recommending any repair so you see exactly what's there — and pay for exactly the repair that solves it.
CCTV pipeline camera inspection — distance-marked recorded footage
Hydro-jetting — grease, scale, and root mass removal from any line size
Root cutting — electric root cutter on sectional cable machine

Grease trap cleaning and documentation for health code compliance
Multi-fixture restroom service — clogs, valve replacement, partition replacement
Backflow preventer testing, certification, and replacement
Commercial water service — main repair, meter vault work, pressure testing
Scheduled maintenance contracts — monthly, quarterly, and annual programs
Leak Detection & Pipe Repair
Hidden Leak Detection in San Marcos, TX — Non-Invasive
A water bill that jumped 30% for no visible reason. A ceiling stain that keeps reappearing after painting. A soft spot in flooring with no obvious source. These are hidden leak signatures, and every week one runs undetected is more structural damage and higher water costs. Masters Plumbing Service uses acoustic ground microphones, thermal infrared cameras, and precision pressure decay testing to pinpoint leaks in San Marcos homes without speculative wall demolition.
Acoustic detection — supply line failures located to within inches under slab or behind wall
Thermal infrared camera scanning — moisture mapping without wall cuts
Pressure testing — zones isolated to identify the failing branch
Slab leak repair — direct access, reroute above slab, or epoxy lining
Repipe service — whole-house scope, phased access, pressure-tested final system
Gas Line Services
TX-Certified Gas Line Work — Safe & Tested
Every gas job we complete in San Marcos is documented with a written pressure test result. We pull the required permits, coordinate the inspection, and provide you with the inspection record as part of the job documentation.
Gas leak service — detector survey, isolation, repair, documented re-test
Gas appliance connections — range, dryer, fireplace, water heater, generator
New gas installation — outdoor kitchen, generator, pool heater, BBQ
CSST service — bonding conductor installation per current code
Pressure test and permit closeout — required documentation provided

Business Water Heater Replacement Solutions Across San Marcos, TX
When plumbing fails at your commercial property in San Marcos, every hour of downtime has a cost.

Our techs hold separate commercial crew certifications — different code requirements, different fixture types, and different service expectations than residential work in TX.

"Sewer backup the night before Thanksgiving. Masters Plumbing Service arrived within the hour, cleared a grease-and-root blockage, scoped after clearing, and explained every finding on camera. Transparent and fast."
— A. Petrov, San Marcos, TX
San Marcos, TX · Sewer Line Service
★★★★★
"Intermittent hot water for weeks before it stopped entirely. The tech traced it to a failing gas control valve, replaced it with a unit from the truck, and tested through a full heat cycle. Done in under an hour."
— S. Nakamura, San Marcos
San Marcos, TX · Water Heater Repair
★★★★★
"My water bill jumped from $90 to $160 in one month with no change in usage. Masters Plumbing Service ran a pressure decay test, found a 6% pressure loss on the hot side, deployed the acoustic detector on the slab in the utility room, and located the leak at a copper elbow under the slab — 4.5 feet from the wall. They presented three repair options with pricing, I chose the reroute through the wall framing, and the new line has been zero-issue for five months. The detection appointment saved me from speculative demolition."
— L. & G. Abramowitz, San Marcos
San Marcos, TX · Leak Detection / Drain Service
★★★★★
"As a property manager overseeing 22 units, I need a plumbing contractor who shows up, does the work correctly, and doesn't pad the bill. Masters Plumbing Service has been our go-to for two years. Response times are consistent, the techs are uniformed and professional, and the flat-rate invoicing makes budgeting predictable. We've never had a warranty callback that wasn't honored immediately."
— Property Manager, San Marcos

"Faint gas smell in the utility room. Tech ran the detector over every fitting, found a micro-leak at a union fitting that had vibrated loose over years of furnace cycling. Repaired, detector-tested every connection, manometer documented."

FAQ
Water Heater Replacement FAQ — Answers for San Marcos, TX Homeowners
These are the actual questions our dispatchers and technicians answer every day in San Marcos, TX.
For emergency calls in San Marcos, our dispatch target is 30–60 minutes from the moment we confirm your address and assign a technician. We stage technicians throughout San Marcos — not at a single central shop — which keeps our actual drive times short. Non-emergency scheduled calls are booked in specific time windows so you're not clearing your whole day for a "sometime between 8 AM and 5 PM" appointment.
Yes — every time, without exception. Our technicians in San Marcos, TX present a written flat-rate quote after diagnosing the problem and before beginning any repair work. You review the quote, ask questions, and decide whether to proceed. The price you approve is the price you pay — we don't add labor time or material markups after the fact.
Masters Plumbing Service's emergency dispatch in San Marcos, TX is available around the clock, 365 days a year. The emergency services we handle after hours in San Marcos include: burst and ruptured pipe repair, active sewer backups, water heater failure (gas and electric), major drain blockages affecting multiple fixtures, gas line leaks (after utility shutoff), frozen pipe response, and main water line failures.
We also background-check every technician before hire and re-screen annually. Your home and family's safety matters, and we staff accordingly.
We document warranty terms specifically because verbal warranties are unenforceable and lead to disputes. When you get a receipt from Masters Plumbing Service, the warranty terms are on that receipt — not implied, not "of course we'd come back" — actually written down.
For active water leaks: locate your main water shutoff valve (typically at the meter, in the utility room, or under an exterior wall) and close it clockwise until it stops. Move valuables off wet floors. Don't use electrical outlets near standing water. For sewer backups: stop using all drains and toilets immediately — continued use worsens the backup. For gas smells: leave the building, don't operate any switches, and call your utility company's emergency line from outside first.
The quickest self-check: shut off every fixture and appliance in the house (including ice maker lines and irrigation if connected), then watch your water meter for 15 minutes with nothing running. If the meter dial or leak indicator is moving, water is escaping the supply system somewhere. Other indicators include an unexplained increase in monthly water usage, ceiling stains that recur after painting, soft spots in flooring, mold odor without visible source, or the sound of running water inside walls with all fixtures off.
Yes. Masters Plumbing Service serves both residential homeowners and commercial property owners, managers, and operators throughout San Marcos, TX. Our commercial team handles restaurant drain and grease trap service, office building fixture repair, multi-unit residential systems, backflow preventer testing and certification, commercial water heater service, and after-hours emergency response for business properties.
Cases where excavation is required: fully collapsed pipe sections, severe pipe belly (negative grade that holds sewage), and pipe offset too severe for lining to bridge. We scope before recommending anything and show you the camera footage so you can see which category your pipe falls into.
Same-day water heater replacement is available in San Marcos for the most common residential tank sizes — our trucks carry 40 and 50-gallon gas and electric units. If your unit is gone and you need hot water today, call us.
Plumbing costs in San Marcos, TX vary significantly based on the type of repair, pipe material, access conditions, and parts required. Rather than give you a range that's too wide to be useful, Masters Plumbing Service provides a flat-rate quote after on-site diagnosis — before any work starts. That quote is accurate because we've seen the specific failure, not estimated based on a description.
Pulling permits matters beyond legal compliance: an unpermitted plumbing repair can void homeowner's insurance coverage for related water damage and can create title issues when selling the property. We handle permit procurement and inspection coordination as part of the job — permit costs are disclosed in your flat-rate quote.
