Six jobs around one valve
Backflow assemblies keep used water from running back into the supply. We test them, fix them, install them and plan around them.
Annual test and report
A gauge test of each assembly, results written on your utility's form and the report filed for you.
Every check and relief valve read
A copy of the report for you
Repair and rebuild
When an assembly fails, we show you the reading, quote the rebuild in writing and retest after the work.
Repair price in writing first
Retest before the report goes in
New and replacement assemblies
Sizing, installing and permitting an assembly where a survey or a failed one shows you need it.
Permit pulled where your city asks for one
Tested before we leave
Irrigation shutoffs and winterizing
We find, tag and exercise your shutoffs, blow out lines before the first hard freeze and test the assembly at spring start-up.
Shutoff locations written on a site card
Start-up and winter visits on the calendar
Cross-connection surveys
A walk of your site to find where water could flow back, and which assemblies protect each spot.
A site list you can hand your utility
Chemical feeds and well houses included
Test programs for many sites
One list, one calendar and one folder of reports for HOAs, districts and managers with assemblies at many addresses.
Reminders before each due date
Tests grouped by route
What you have
Three assemblies you will see on a site
Your utility's notice names the type. Here is how to spot each one and what the test reads.
| What the test reads | Where you find it | |
|---|---|---|
| Pressure vacuum breaker (PVB) | What the test readsWater on, gauge on the test cocks: the air inlet should open at a set pressure and the check should hold. | Where you find itOn irrigation lines, mounted above the highest sprinkler head, with a bonnet on top. |
| Double check valve (DCVA) | What the test readsA gauge across each check to read how tightly it holds against reverse flow. | Where you find itTwo check valves in a line on low-hazard connections, often at a meter or in a vault. |
| Reduced pressure assembly (RPZ) | What the test readsBoth checks and the pressure at which the relief valve opens. | Where you find itTwo checks with a relief valve between them, used where backflow could carry chemicals. The relief port may drip or spit when it fails. |
