Add-ons for your annual test
Protect your assembly while we're already on site. Add bags, cages, or a cement base to your test request and our office will confirm the fit, the final price, and your appointment by phone. No payment is taken here and nothing is scheduled automatically.
Annual test: $85 for assemblies 2" and under within Tucson city limits. Add-ons are requested with your test — our office schedules the visit.
Insulation bags
An exposed backflow assembly can freeze and fail in a Tucson cold snap. We make insulated protection bags — new and reconditioned — sized to fit your assembly.
Custom-fit insulation bag (new)
Made to fit your exact assembly — popular for Gladden Farms & Rancho Marana homes.
Open-ends bag (new) — fits ID 20"W × 14"H
New insulation bag with open ends for larger assemblies.
Closed-ends bag (reconditioned) — fits ID 22"W × 12"H
Like-new closed-ends bag at a reduced price.
Protective cages
A locking steel enclosure that deters theft and protects the assembly from damage. Sized to your assembly and anchored on site.
Backflow enclosure cage
Powder-coated steel cage with lockable lid. Tell us your assembly size at checkout and we'll confirm the fit.
Cement bases
A level, poured base keeps the assembly stable, off the ground, and gives a cage something to anchor to.
Cement base pad
Poured and finished to fit your assembly and cage. Quoted after we see the site.
