Sun City homeowners call Liberty for tankless water heaters because we're local to the Valley, licensed, and answer the phone 24/7. Sun City is Arizona's original 55+ community, with homes from the 1960s and 70s, the oldest plumbing we regularly service. That means galvanized and polybutylene pipe, aging slab copper, and a lot of demand for ADA and comfort-height fixtures. We work patiently and explain things clearly with the retiree homeowners here. You'll get the truth about what's going on, your options in plain English, and a fair price upfront.

Sun City is the original Del Webb active-adult community, built from 1960, which makes it the oldest housing stock we routinely service and a place with very specific plumbing realities. Many of these homes still have their original galvanized steel or, in certain eras, polybutylene supply lines, both of which are now living on borrowed time: galvanized corrodes shut from the inside and rusts the water, while polybutylene becomes brittle and fails at the fittings. Repipes are a steady part of our Sun City work, replacing those failing original lines with PEX or copper before a hidden failure floods a slab home.

What we see on Sun City plumbing

  • Polybutylene and galvanized pipe needing full repipe
  • 1960s–70s slab copper at high slab-leak risk

How a Sun City tankless water heaters call goes

  1. Gas & venting check

    Tankless needs adequate gas supply and sealed venting, we verify your line can feed it before quoting.

  2. Scale protection built in

    We pair every install with a softener or an isolation/scale-filter kit so AZ minerals don't choke it.

  3. Annual descale plan

    We set you up on a yearly flush so the warranty stays valid and flow stays full.

Tankless Water Heaters in Sun City, FAQ

Is tankless worth it in Arizona?
Yes, if you stay on top of the annual descaling. Our hard water will clog an unmaintained unit fast. Put a softener in front of it and it's a 20-year appliance.
Can my gas line handle it?
More often than not the existing line is undersized for a tankless burner. We measure it and upsize if it needs it, and that's part of the quote.
Do I really need a water softener with a tankless heater in Phoenix?
Pretty much, yes. Our 16-20 grain water scales the narrow heat exchanger fast, and unsoftened water can ruin a tankless unit in a couple of years. Soften the water and descale it yearly and a tankless will reach its long lifespan out here.
How often does a tankless need to be flushed?
About once a year in our hard water, and more often if you don't have a softener. Units with isolation valves make the descaling flush quick. If yours doesn't have them, adding them is worth the trouble.
Will a tankless give me unlimited hot water for the whole house?
It won't run out of hot water, but flow rate is the limit. Run two showers and a dishwasher at once and you can outrun a single unit, especially in winter when the incoming water comes in colder. Size it right for your peak demand and it works.
Why does converting from a tank to tankless cost more than I expected?
Gas tankless units usually need a bigger gas line and a new sealed vent, and electric models can mean a major panel upgrade. Those home-infrastructure changes, not the unit itself, are what drive the retrofit cost. We'll size all of it up front.
Does a tankless work as well in Flagstaff as in Phoenix?
It works, but the incoming water up north runs colder, so the unit has to raise the temperature further. That drops its effective flow rate. A unit sized right for Phoenix may need to be bigger to do the same job in the high country.
My Sun City home might have polybutylene or galvanized pipe. Should I repipe?
Likely yes. Sun City's 1960s-70s homes often have original galvanized or polybutylene supply lines, and both fail with age, galvanized by corroding and rusting the water, polybutylene by going brittle at the fittings. A repipe to PEX or copper before a hidden failure floods the slab is the smart move. We'll inspect what you've got and explain it plain.
