Real Answers to the Questions San Antonio Homeowners Ask Most
From drain clogs to gas line safety, here's what San Antonio homeowners want to know before they call a plumber — answered straight, no upsell.
We pulled these questions from the ones we hear most often on calls, plus the ones homeowners search for most before they ever pick up the phone. If you don't see your specific issue below, call us at (726) 895-9998 — we're happy to talk through it before you book anything.
General & Service Questions
How do I know if I have a plumbing emergency that needs an immediate call?
If you have an active leak you can't stop, a sewage backup, no water at all, or you smell gas, that's an emergency — stop using the affected fixture and call (726) 895-9998 right away. A slow drain or a dripping faucet can usually wait for a scheduled visit. If you're not sure which one you're dealing with, our team can help you sort that out over the phone before we dispatch anyone. See our emergency plumbing page for more on what qualifies.
Do you charge for estimates or service calls?
We diagnose the issue on-site and give you a free, written estimate before any repair begins, so you know the price before you commit to anything. There's never a surprise total once the work is finished.
How quickly can Silverback get to my home?
For emergencies, we prioritize same-day response across San Antonio and the surrounding communities we serve. For routine repairs and installations, we'll schedule a time that works for you, typically within a day or two depending on demand.
Do you offer financing or payment plans for larger repairs?
Options can vary depending on the size and type of job, so rather than guess here, give our office a call at (726) 895-9998 and we'll walk you through what's currently available for your specific situation.
Are you licensed and insured, and can I see proof?
Yes — every job is performed under Responsible Master Plumber License #43333, issued by the Texas Board of Plumbing Examiners, and we carry liability insurance for work performed in your home. You're welcome to ask to see license details before any work begins.
Drains & Sewer Lines
How can I tell if my drain just needs cleaning or if there's a bigger problem?
A single slow drain is usually a local clog — hair, grease, or soap buildup near the fixture. If multiple drains are slow at the same time, or one drain gurgles when another fixture runs, that often points to a deeper line issue that needs a professional look. See our drain cleaning page for the signs we check for.
Is it safe to use store-bought drain cleaners like Drano?
We'd skip it. Chemical drain cleaners can corrode older pipes from the inside with repeated use, and they often don't clear a blockage that's deeper in the line. A plumbing snake or hydrojetting clears the clog without the long-term pipe damage.
What are the warning signs of a sewer line problem?
Watch for gurgling drains, sewage odors in the yard or house, slow drains throughout the home, or an unusually lush, soggy patch of grass over the line. Any of these — especially more than one at once — is worth getting inspected before it turns into a backup. More on our sewer line repair page.
Can tree roots actually damage a sewer line, and how is that fixed?
Yes — roots are drawn to the moisture and nutrients inside sewer pipes and can work into small cracks or joints over time, eventually blocking or breaking the line. Depending on how far it's progressed, we fix it with hydrojetting, a spot repair, or trenchless lining rather than defaulting straight to a full dig-up.
Water Heaters & Water Softeners
How often should my water heater be flushed or drained?
Once a year is the general rule, but San Antonio's hard water builds sediment faster, so every six months is safer if your home isn't softened. Banging or popping noises, fluctuating temperatures, or rust-colored hot water are signs sediment has already built up.
How do I know if my water heater needs to be repaired or replaced?
Age matters most — most tank water heaters last 8 to 12 years, and a unit near or past that range is usually a better candidate for replacement than another repair. We'll tell you honestly which option makes sense for your unit rather than defaulting to the pricier one. Full breakdown on our water heater page.
How do I know if I need a water softener for San Antonio's hard water?
White spots on dishes and glassware, soap that won't lather well, and scale buildup around faucets and showerheads are the classic signs. San Antonio's water runs hard enough that most homes benefit from a softener — it's less a question of "if" and more about timing it before it shortens the life of your appliances.
How much maintenance does a water softener need?
Mainly keeping the brine tank stocked with salt — check it monthly given how hard San Antonio's water runs. Beyond that, we recommend a professional check every 6 to 12 months to confirm the resin bed and valve are still regenerating properly. More in our water softener page.
Gas Lines & Gas Fireplaces
What should I do if I smell gas in my home?
Don't flip any switches or light anything — leave the house, and call CPS Energy's emergency line along with our 24/7 number once you're outside. We'll inspect the line and make it safe; this is one situation where waiting isn't an option. Full detail on our gas line page.
Do I need a permit for gas line or gas fireplace work?
In most cases, yes — gas work in San Antonio requires a permit and inspection, which is part of why it should go through a licensed plumber rather than a handyman. We handle the permitting as part of the job so you're not left chasing paperwork.
Toilets, Faucets & Disposals
What can and can't go down a garbage disposal?
Soft food scraps and a steady stream of cold water are fine. Grease, fibrous vegetables like celery, coffee grounds, and bones are the usual culprits behind jams and odors — keep those in the trash or compost instead. Full list on our garbage disposal page.
Why does my toilet keep running, and is it wasting water?
It's almost always a worn flapper or a fill valve that isn't seating correctly, and yes — a constantly running toilet can waste well over 100 gallons a day. It's a quick, inexpensive fix in most cases, so there's no reason to let it run while you decide whether it's worth addressing.
Why is my faucet leaking, and is it a quick fix?
Usually a worn washer, O-ring, or cartridge inside the handle — straightforward to replace once we've confirmed which part has failed. The bigger risk is leaving it, since a slow drip adds up on your water bill and can damage the cabinet or counter underneath over time.
Leaks & Maintenance
How can I tell if I have a hidden leak in my yard or under my slab?
An unexplained spike in your water bill, a soggy or unusually green patch of lawn, or the sound of running water when everything's off are the main clues. We use acoustic listening equipment and moisture detection to find the exact location before we dig, so we're not tearing up more yard than necessary. More on our yard leak detection page.
Do you offer a plumbing maintenance plan, and what's included?
Yes — our maintenance plan covers a scheduled inspection of your major plumbing systems, including your water heater, fixtures, and visible piping, so small issues get caught before they become emergencies. It's the same idea as an oil change: cheaper and easier than waiting for something to fail. Details on our maintenance plan page.
