When replacement is the right call in Lewisville
We recommend replacing an assembly in Lewisville when the body or bonnet is cracked from a freeze, the model is obsolete and rebuild kits are no longer produced, corrosion has pitted the seats, the assembly is the wrong size or type for the hazard, or repeated repairs are no longer economical. Newer assemblies are also easier and cheaper to test and rebuild going forward.
Code-compliant installation
We install USC-approved assemblies sized for your service and hazard level, set at the height and orientation City of Lewisville Public Services requires, with proper clearances for future testing. For irrigation we install double check and pressure vacuum breaker assemblies; for domestic and high-hazard applications, reduced pressure principle assemblies; for fire lines, DCDA and RPDA units. Freeze protection and insulated enclosures are available for exposed Lewisville installations.
Tested and filed before we leave
Every new assembly is tested immediately after installation, and we submit that initial report to City of Lewisville Public Services on your behalf. You get a copy for your records plus the due date for next year's test, and we can put your property on our annual reminder list.
