Typical arrival 30–60 min
When a drain backs up, a pipe bursts, or your water heater quits overnight, you don’t have time to wait around. You need someone who shows up fast, fixes it right the first time, and tells you the cost before any work starts. That’s what homes and businesses across San Antonio get from us, every call.
San Antonio water tests 15–20 GPG — very hard. Scale shortens water heaters and clogs aerators in every home here. A properly sized softener fixes all of it.

Most people calling at eleven at night are afraid of two things at once: that they are overreacting, and that they are about to be handed a blank check. Here is the honest line between the two.
People search for why water softeners are banned in Texas. They are not. What San Antonio does have is a permit rule that works backwards from what you would expect.
Everyone says San Antonio water is hard. Almost nobody quotes the figure, and the one place you would expect to find it does not print it at all.
We stand by our products and services 100%, and we provide a 5-year warranty free of charge.
Any permits or inspections needed to complete the job are covered in our fees and handled accordingly.
Yes we can, however warranty will only cover workmanship.
Yes — Silverback Plumbing & Drain is licensed through Mark Vargas, Responsible Master Plumber #43333, licensed by the Texas Board of Plumbing Examiners. Any San Antonio plumber should be able to give you a license number on request; if they can’t, that’s worth treating as a red flag before any work begins.
Yes. Every job starts with a diagnosis, not a guess — we identify the actual problem first, then give you a clear, written price before any repair, replacement, or installation begins. You’re never billed for work you didn’t agree to in advance.
We’ll tell you honestly, based on the age and condition of the unit or line in question — not based on which option costs more. If a repair will reliably solve the problem, that’s what we recommend; if the unit’s at the point where repairs are just delaying an inevitable replacement, we’ll explain why and let you decide with full information either way.
Typical arrival: 30–60 minutes, depending on demand and location.
Silverback Plumbing & Drain provides licensed plumbing and drain service for homes and businesses throughout the San Antonio area. From emergency repairs to routine maintenance, we diagnose the problem, explain the fix, and get it done right the first time.
