The old tank out, the new one in, hot water tonight.

When the tank is leaking or the heater is old enough that repairs no longer make sense, replacement is the honest answer. Royal Flush Affordable Plumbing removes the old unit, installs the new one with new connections, venting and a pan, and hauls the old tank away, usually the same day you call.

  • $100 off installation
  • Same day on most replacements
  • Old unit hauled away

Signs you need this

When replacement beats repair, plainly.

We will repair a heater that can be repaired. These are the cases where it should not be.

The tank is leaking

Water from the tank body, not a fitting, means the steel has rusted through. No repair holds.

It is past its expected life

Tank heaters in Houston typically give ten to fifteen years. Past that, a repair buys months.

Rusty hot water

The tank is corroding from the inside. The anode is gone and the steel is next.

A second repair in a year

When parts fail in sequence, the unit is at the end.

It no longer keeps up

A household that has grown past the tank size is better served by a bigger unit or a tankless.

Gas or electric bills climbing

Sediment and scale make an old heater work harder for the same hot water.

What we actually do

Removed, replaced, brought up to code.

The old heater is drained and disconnected and carried out. The new one is set on a pan with a drain line where the location calls for it, connected with new supply lines, shutoff and gas flex, vented correctly, and fitted with an expansion tank if the system needs one. It is filled, purged, fired, set to temperature and checked at the farthest tap.

Many Houston heaters were installed without a pan, an expansion tank or proper venting. A replacement is when those get put right, and we tell you which apply before you approve the price.

  • Same day where stock allowsCommon sizes are on the truck or an hour away.
  • Code items donePan, expansion tank, venting and relief piping handled, not skipped.
  • Old tank hauled awayIt leaves with us.
How we fix it

A replacement, start to finish.

Here is how a same-day replacement goes.

Tank leaking now?

Shut the cold inlet valve on top of the heater and the gas valve or breaker. Put towels down and call.

    Right away

    You tell us the size and fuel

    The label on the heater gives gallons and gas or electric. That is enough to bring the right unit.

    On arrival

    Confirm and quote

    We check the location, venting and connections and give you one price before starting.

  3. 3

    Drained, removed, new unit set and connected, code items done.

  4. 4
    Before we leave

    Fill, fire, test, haul

    Hot water confirmed at a tap, the area cleaned, the old tank gone.

What affects the price

What moves the price on a replacement.

Upfront, with the unit named. The variables:

Size and fuel

A like-for-like 40 or 50 gallon tank is the simplest replacement.

Switching to tankless

More to install, less to run. We quote it alongside if you are interested.

Location

Garage and closet units are quick. Attic units take longer to remove and set.

Code items

Pan, expansion tank, venting or a new shutoff where the old install lacked them.

The coupon

$100 off any water heater installation. Mention it when you book and show it at the time of service.

Water Heater Replacement FAQs

Replacement questions we hear every week.

Still not sure? Call and describe the problem. We’ll tell you honestly whether it’s a 20-minute fix or a job worth quoting.

Ask a plumber: 281-612-1015
01How long does a water heater last in Houston?
Tank heaters typically give ten to fifteen years; tankless units longer with regular descaling. Hard water and skipped flushes shorten both. The date is on the serial number label, and we can read it for you.
02Can you replace it the same day?
Usually, for common tank sizes. Unusual sizes, tankless conversions or attic installs may need a scheduled visit, and we tell you on the phone.
03Should I upgrade to tankless when I replace?
If you run out of hot water, want lower running costs, or need the space, it is worth a quote. If the current tank serves the household well and the budget matters, a like-for-like tank is the sensible choice.
04What happens to the old heater?
We take it with us and dispose of it.
05Is there a coupon?
Yes. $100 off any water heater installation. Mention it when you book and show it at the time of service.
