Flush Irrigation Backflow Test-Cock Rings

An irrigation backflow preventer is not a paver detail, but the paver field around it is. Pinellas testers need the test cocks, the relief valve, and the shutoffs clear once a year. PaverForge Hardscapes cuts a flush access ring or a framed collar so the assembly stays serviceable after the drive or side yard is paved.

We do not set, certify, or relocate the backflow device. The irrigator or plumber owns the assembly and the height above grade. We build the paver collar to the vault or pad they leave, with a removable lid section or an open framed ring so a tester is not prying pavers off the bonnet.

The mistake we fix most often is a field that was run tight to the test cocks, then polymeric sand packed into the relief-valve opening. The next test cracks the pavers or, worse, the assembly gets buried and fails the inspection. A defined ring avoids both.

• Collar sized to the existing reduced-pressure zone or double-check pad

• Grade kept below the relief-valve opening

• Edge restraint stopped at the ring so the field can move without binding the pipes

• Separate hose-bib ring if the bib shares the same side-yard bay

This is a common add-on when we rebuild a driveway in Dunedin, Largo, Clearwater, or St. Petersburg and the backflow sits in the new field. Call 727-490-9798 before the irrigator buries the pad, or we can cut a ring into an existing field if the base around the assembly is still sound.

If the assembly itself is low, leaning, or leaking, get the licensed tester out first. Paving around a failing device does not make it pass.
