Tankless Water Heater Replacement

A tankless swap done once, done right, and explained so you know what was done and why. That is the whole pitch, and it is why Wilmer homeowners keep the same number.

How Paul handles it

Nothing gets sold that the house does not need. Running a one-truck shop means there is no quota pushing a replacement when a repair would hold, which is the single biggest difference between this and a franchise van.

Here is what actually happens. Paul comes out, looks at the real thing instead of guessing from the doorway, and tells you what he found. If it is small, he says it is small. If it is going to be a job, he says that too, and he says why before anything gets taken apart.

You are not hiring a company. You are hiring the owner, and the owner is the person standing in your utility room. The longer version of how this shop runs is on the about page, and the work itself is in the gallery.

What matters on a tankless water heater replacement job

  • The old unit tells you how to set the new one

    Before anything comes out, the existing setup gets looked at for what failed and why. Undersized supply, a missing shutoff, a connection that was never right, a drain that was always marginal. Installing a new fixture onto the same bad conditions just resets the clock on the same complaint.

  • Shutoffs and access get fixed while the wall is open

    The cheapest time to put a proper shutoff on a fixture is while the work is already happening. Houses where every repair means closing the main are houses where small problems turn into emergencies, and that is usually a twenty dollar part somebody skipped years ago.

  • It gets tested before anybody leaves

    Pressure held, connections dry, drain flowing, no movement in the fixture. A leak that shows up two hours after the truck pulls away was a leak when the truck was still there, and testing is how you catch it then instead of later.

  • What happens after the work is done

    The repair gets tested before anybody packs up, the work area gets cleaned, and you get told what was done and what to watch for. If something is going to need attention in a year, you hear about it now rather than discovering it later.

  • What a real diagnosis looks like

    The first thing that happens is somebody looks at the actual failure instead of the symptom you can see from the doorway. That means opening the panel, running the camera, putting a meter on it, or isolating the zone. It takes longer than guessing and it is the only part of the job that decides whether the repair holds.

How to tell what you’re dealing with

Knowing which of these sounds like your house makes the first call a lot shorter.

  • If it only happens with hot water

    That isolates it to the heater or the hot side of the house, which is a much shorter list than the whole house.

  • If a tankless unit runs lukewarm

    Scale in the heat exchanger is the usual cause in water like ours, and a descale fixes it more often than people expect.

  • If a tankless unit cuts out mid-shower

    Either the flow drops below what the unit needs to fire, or it is an ignition or sensor fault. The error code on the unit usually says which.

  • If the water smells or stains

    Iron, sulfur and sediment are water quality problems. A test tells you which filtration is worth having.

How a call goes, turn by turn.

From the phone ringing to the truck pulling away, there are four stops and none of them involve a sales pitch.

  1. Start

    Paul picks up

    You call (251) 421-0367 and the man who’ll do the work answers. No phone tree, no dispatcher, no waiting for a callback from somebody else.

  2. Then

    He’s on the way

    You get a real time instead of a four-hour window, and he keeps it. One review has him there at 9 for a 7 a.m. call; another, on the way within twenty minutes.

  3. Then

    Finds the real cause

    A camera, a meter or a pressure test before any number gets said out loud. A guess is how a repair comes back.

  4. Arrive

    Fixed and tested

    Tested before the truck leaves. You hear what was done and what to keep an eye on, in plain words.

Things worth doing yourself

None of this needs a plumber. It’s the short list that prevents the calls nobody wants to make.

  • Water heater Check the T and P valve and look at the base of the tank for rust or damp. Five minutes, twice a year.
  • Drains Hot water and a drain screen beat chemical cleaner. Caustic drain products damage older pipe and make a cable job messier later.
  • Hose bibs Disconnect hoses before the first hard freeze. A connected hose holds water in the bib and that is what splits it.
  • Toilets A drop of food coloring in the tank will tell you in ten minutes whether the flapper leaks.
  • Grinder pumps Test that the alarm actually sounds. An alarm nobody has checked is not an alarm.

Straight answers

Still not sure? Ask Paul directly.

Repair or replace the water heater?

Elements, thermostats, valves and anode rods are repairs. A leaking tank is a replacement. Paul tells you which one you have before anything gets sold.

Tank or tankless?

It depends on how much hot water the house uses at once and what the gas or electric service can carry. That gets worked out at the house, not on a sales sheet.

Do you work on older homes?

Yes. A lot of the housing stock here is older, and cast iron, galvanized and polybutylene all behave differently. That is diagnosis work, which is the part that matters.

Who actually shows up?

Paul Evans. Every time. LT Drain is a one-truck, one-man operation on purpose, so the person who answers your call is the person who does the work.

Are you licensed?

Licensed Master Plumber MP4379, bonded and insured. The number is printed on this site because you should be able to check it with the Alabama plumbing board.

Do you charge to come look?

There is a diagnostic visit and it is explained on the phone before he drives out. You will know what the visit covers before you agree to anything.
