Is It Time For A Checkup?
Maintenance works best before there's a problem to point to. Here's how to tell it's due.
We'll ask the age of your unit and when it was last serviced, if ever. That tells us what to expect and what parts to bring, especially if an anode rod replacement looks likely.
We flush the tank to clear sediment, inspect the anode rod, test the pressure relief valve, and check all connections for early wear. We'll show you what we find and explain anything worth watching.
We confirm the unit is running efficiently and note anything that might need attention before next year's visit. You'll leave with a clear picture of your water heater's condition, not just a receipt.
Preventive Water Heater Care
Most water heater failures we see trace back to two things: sediment nobody flushed out, and an anode rod nobody checked. Both take an hour to address and both add real years to a unit's life.
We check the parts that actually fail first: sediment levels, the anode rod, and the pressure relief valve. You'll get a clear picture of your unit's condition every visit.
Maintenance pricing is straightforward, and if we find something that needs repair, you'll get a separate quote before we touch it.
San Antonio's hard water leaves mineral deposits behind every time the tank heats a new batch of water. Over months, that settles into a layer of sediment at the bottom. The burner has to work through that layer to heat the water above it, which costs you money on every energy bill even before the tank starts making noise.
Left alone for years, that sediment layer hardens and becomes difficult to remove completely, and it can trap heat against the tank's metal in a way that accelerates corrosion. A flush at the one-year mark is a lot easier than one at year five.
A tank water heater's rated lifespan assumes reasonable maintenance. Skip it entirely and you're more likely to see failure on the early end of that range instead of the late end. The anode rod is the clearest example: it's designed to corrode instead of the tank, but once it's used up, the tank itself starts absorbing that damage.
A basic annual visit covers the parts that matter most:

I am having a weird issue with intermittent dampness in my garage. Roger spent about 1.5 hours trying to locate the problem. He assured me it was not a plumbing problem and told me not to worry about the service call.

A standard visit includes flushing the tank to remove sediment, checking the anode rod for corrosion, testing the pressure relief valve, and inspecting connections for early signs of leaks or wear. It's a check of the parts most likely to cause a failure down the road.
Once a year is the standard recommendation. San Antonio's hard water builds sediment faster than in areas with softer water, so skipping years tends to show up as reduced efficiency and a shorter tank lifespan.
Yes. Sediment sitting at the bottom of the tank acts as insulation between the burner and the water, forcing the unit to work harder and use more energy to reach the same temperature. Heavy buildup left unchecked for years can also lead to popping noises and premature tank failure.
The anode rod is a sacrificial metal rod inside the tank that attracts corrosion so the tank itself doesn't rust through. Once it's fully corroded, the tank starts taking the damage instead. Checking and replacing it during maintenance is one of the cheapest ways to extend a water heater's life.
It significantly reduces the odds. Most premature failures trace back to sediment buildup or a spent anode rod, both of which routine maintenance addresses directly. It won't make a unit last forever, but it typically adds years to its usable life.

Water heater maintenance is one of the few plumbing visits that's genuinely cheaper than skipping it. A flush and inspection costs a fraction of a full tank replacement, and the whole point is to prevent that replacement from happening years ahead of schedule.
We treat every maintenance visit the same way: flush the sediment, check the anode rod, test the valve, and look over every connection. It's not a rushed formality, and you'll get a straight answer about your unit's condition either way.
If your water heater has never had a maintenance visit and it's a few years old already, that first flush can be more involved than a routine annual one. We'll handle it and tell you honestly what shape the tank is in afterward.
