What a domestic backflow assembly does in Lewisville

The domestic assembly protects Lewisville's public water supply from the water inside your building. High-hazard uses — food service, medical suites, boilers, chemical mixing, cooling towers — are typically protected by a reduced pressure principle assembly (RPZ) at the point of service. City of Lewisville Public Services requires annual certification, and a missed test can lead to violation notices or a hold on your certificate of occupancy or health inspection.

Testing without shutting your business down

Testing a domestic assembly briefly interrupts water to the building, so timing matters. We schedule Lewisville restaurants and clinics before opening or after close, and coordinate with facility staff on apartment and office buildings so tenants get notice. Actual isolation time is usually under 15 minutes per assembly.

Multi-site and portfolio testing

If you manage several properties in Lewisville or across DFW, we can put every assembly on one annual schedule, send one consolidated invoice, and track due dates for you. Property managers use us because reports get filed with City of Lewisville Public Services without follow-up phone calls.
