Sizing the Right Replacement Assembly

The wrong backflow preventer is worse than none: it restricts flow, fails inspection, and sometimes has to be ripped back out at the homeowner's expense. Sizing matters. Hazard level matters. So does orientation, elevation, and sun exposure on the SW Florida coast.

We replace:

  • PVB / SVB — residential irrigation lines, small-scale low-hazard assemblies
  • DCV — commercial irrigation, low-hazard cross-connections, small fire lines
  • RPZ — fire sprinkler systems, medical, food service, industrial, any high-hazard connection

Every replacement includes proper test-cock orientation for future service access, UV-resistant placement where applicable, and a full startup certification test — filed with your water authority the same day.

When You Need a Replacement Backflow Preventer

Failed Test, Beyond Repair

Cracked bodies, corroded internals, or assemblies older than 15 years often cost more to rebuild than to replace. We give you the honest numbers both ways.

Impact or Corrosion Damage

Vehicle strikes, lawn-equipment hits, and long-term corrosion can crack the body or fittings. Once that happens, a rebuild kit won't save it — you need a new assembly.

Obsolete Model, No Parts

Some older Febco and Wilkins models are out of production. When rebuild kits are no longer made, replacement is the only path back to compliance.

Frequently Asked Questions

Do I need a permit to replace a backflow preventer?

Yes — in North Port and Englewood, a plumbing permit is typically required for backflow replacement when the assembly size or location changes. We pull the permit, swap to code, and schedule the inspection.

How long does a backflow replacement take?

A typical residential PVB swap is 2 to 4 hours. Commercial RPZ replacements range from half a day to a full day depending on pipe size and location. We include the certification test in every replacement.

What brand of backflow preventer do you use for replacements?

We work with Febco, Wilkins, Apollo, and Zurn assemblies — the four brands with the best long-term parts availability in Florida. Brand choice depends on assembly type and local parts stock for future repairs.

Should I repair or replace my backflow preventer?

Repair when the assembly is under 15 years old, the body is intact, and a rebuild kit is still made. Replace when the body is cracked, the model is obsolete, or you have had multiple failures in recent years. We give you straight numbers both ways.
