2 Signs

3 Repair or replace

Should I repair or replace my water heater?

Water heaters are simply built, and many problems are a part, not the whole heater. A leaking tank is the line: once the tank itself leaks, it's time to replace.

Usually a repair

  • Heating elements
  • Valves, including the drain valve (with a flush)
  • Anode rod
  • Gas valve, pilot or igniter
  • Leaking fittings, caught before they damage the heater

Usually a replacement

  • The tank itself is leaking
  • Rust along the seams
  • Dents and cosmetic damage: your call, we price the repair and the replacement

How long do they last here? It depends on your water and on maintenance. We’ve seen tanks fail in 4 years and last 40. Without maintenance, many fail in about 4 to 6 years; with a yearly flush, most last well over 10.

4 Which water heater

Tank, tankless or hybrid?

Most homes here have an electric tank. We handle water heater installation for Rheem, Ruud and Navien, and we can special-order any brand and type you want.

Rheem electric tank water heaterTank about 2.5 hours

The most common water heater in South Florida, usually electric. Lowboy and short models fit condo closets, and non-metallic tanks are available for homes near the coast.

Rheem electric tankless water heaterTankless about 4 hours

A tankless water heater keeps hot water coming when the shower, the laundry and the kitchen run at once. Hard water is its biggest enemy. An optional water filter ahead of it and yearly service help it last longer.

Rheem hybrid heat pump water heaterHybrid heat pump about 4 hours

An electric water heater that uses a heat pump to heat the water, for lower running costs than a standard electric tank.

Gas water heaters: yes, where the gas line and venting are already in place. We don’t install new gas lines.

What size water heater do you need?
HouseholdLight to regular useHeavy useTypical home
1 to 2 people30 gallons40 to 50 gallonsCondo or 1 bedroom
2 to 3 people40 gallons40 to 50 gallons2 bedrooms, 2 baths
3 to 4 people40 gallons50 to 75 gallons3 bedrooms
5 or more people50 gallons75+ gallons4 bedrooms or more

Heavy use means a large soaking tub, two showers running at once or laundry most days. A rule of thumb, not a promise: the estimate sizes it to your home. Tankless is sized by how many taps run at once, not by gallons.

5 Install day

What happens on installation day?

  1. PermitPulled for every installThe work is inspected, so it meets code.
  2. InstallAbout 2.5 to 4 hoursAbout 2.5 hours for a tank, about 4 for tankless, hybrid or gas.
  3. To codeDone to codeEvery install is done to code, including an expansion tank when your home needs one.
  4. TemperatureLeft at the factory settingFor scald safety with kids and seniors in the home.

We haul the old water heater away. We install water heaters we supply, so the warranty is clear. Want a specific brand or model? We special-order it.

6 Before you call

What should I do right now?

It’s leaking

Shut off the water at the main shutoff and turn off the heater’s breaker. Stay clear of the water near the heater.

No hot water

Check the heater’s breaker and reset it once. If it trips again, leave it off and call us.

Valve dripping

A dripping safety valve isn’t normal. Call a plumber to find out why.

Smell gas?

Turn the gas off at the source, leave the house and call 911.

Don’t know where your main shutoff is? Ask the plumber on your next visit to show you. Turn it slowly, over about 10 seconds.

FAQ

Water heater questions

How long does a water heater last in South Florida?

It depends on your water and on maintenance. Without maintenance, many tanks fail in about 4 to 6 years; with a yearly flush, most last well over 10. A tankless unit with a water filter and yearly service lasts 8 to 10 years or more.

Tank or tankless: which water heater should I get?

A tank suits most homes and costs less to install. Tankless keeps hot water coming when several taps run at once, which helps larger families. If the flow is more than the unit is sized for, the water won't get hot enough, so we size it to your home.

What size water heater do I need?

As a rule of thumb: 30 gallons for 1 to 2 people, 40 for 2 to 4 people and 50 for 5 or more. With heavy use (a large tub, two showers at once, laundry most days), go up to 40 to 75 gallons or more. The estimate sizes it to your home.

Do you install gas water heaters?

Yes, where the gas line and venting are already in place. We don't install new gas lines.

Is a dripping T&P valve on a water heater normal?

No. The temperature and pressure relief valve opens when the tank gets too hot or the pressure gets too high. A drip means it opened. Call a plumber to find out why.

Will you install a water heater I bought myself?

No. We install water heaters we supply, and we can special-order any brand and type you want.

How do I find my water heater's age?

Look for the manufacturer's label on the side of the tank. It shows the model, the serial number and the manufacture date. Not sure? Text us a photo of the label.

Can one call cover both a plumbing problem and the AC?

Yes. We can send a plumber and an AC technician together. Our licensed plumbing division works alongside our HVAC crews out of the same office, so a water heater or a drain goes through the same phone number as an AC repair. Calls are handled in the order they are received, and most are seen the same day. Water heater replacements follow the same permitted, flat-rate process as a new AC.
