Flush Irrigation Decoder Splice Vaults in a Pinellas Paver Yard

A two-wire decoder splice buried under bedding sand is invisible until the zone dies. Finding it means lifting a patch of patio. A flush splice vault marks the spot and keeps the connectors above the wet base.

What the vault has to do

PaverForge Hardscapes sets the box on compacted base, with the splice loop coiled inside and the lid flush to the paver surface. The lid is traffic-rated if it lands in a drive. Polymeric sand stays out of the frame so the lid still opens after a summer. We do not use the vault as a drain.

The wire path is sleeved under the field. If a later utility cut crosses that sleeve, the vault is the landmark the irrigator uses, not a guess in the middle of the herringbone.

Related boxes we already set

Zone-valve collars, master-valve boxes, and flow-sensor vaults are separate openings. A decoder splice can sit beside them, but it should not share a box with a valve that floods. Label the lid.

PaverForge Hardscapes sets these on Pinellas jobs from St. Pete Beach. Call 727-490-9798 if a smart timer lost a zone and the splice is somewhere under the new patio.
