Bloomington is served by West Valley Water District, so WVWD decides which properties need a backflow assembly and how tests are reported; ask the provider for its program details. On semi-rural lots with animals, troughs and long hose runs can also create cross connections. Call the number on this page to be connected with a local plumber in Bloomington.
Local conditions in Bloomington
Bloomington is an urban unincorporated community between Fontana, Rialto and the Riverside County line. West Valley Water District names Bloomington among the communities it serves, though it wasn't verified that every address is WVWD territory, so check your bill. WVWD's water is a chlorinated blend of local groundwater, Lytle Creek surface water and State Water Project water, and hardness varies by source: about 150 mg/L for Lytle Creek, 84 mg/L for State Water Project water and roughly 140 to 250 mg/L for groundwater. For WVWD's backflow rules, check with the district; customer service is (909) 875-1804, option 3. Every California water supplier must protect its system from cross connections.
Parts of Bloomington remain semi-rural, with residents keeping animals, while warehouse development has replaced some older homes. Both matter here. Troughs filled by a submerged hose are a classic cross connection on animal lots, and new warehouses and commercial buildings come with fire and domestic services that typically carry tested assemblies. Much of Bloomington is also not on municipal sewer and uses private onsite wastewater systems, which has no direct bearing on backflow from the water side but is worth mentioning when a plumber visits.
Common fixes compared
| Fix | Where it fits | Notes |
|---|---|---|
| Hose bibb vacuum breaker | Spigots used for troughs, sprayers, wash-down | Protects one spigot at a time |
| Air gap or float valve above the rim | Troughs and automatic waterers | Keeps the fill point out of the water |
| Pressure vacuum breaker | Irrigation systems | Must sit above the highest sprinkler head |
| Reduced pressure assembly | Higher-hazard commercial and industrial uses | Needs testing and periodic rebuilds |
Signs to call
- A WVWD notice about a backflow test or survey
- Water draining from a relief port when nothing is running
- A trough or waterer filled by a hose that sits below the water line
- Drips, cracks or corrosion on a device
- A new commercial or warehouse tenant with no test history
Timing notes
Summer heat means more trough filling and more irrigation, and that is when a cross connection is most likely to be tested by a pressure drop. Fix hose and trough setups before then. Permits for new plumbing in Bloomington go through San Bernardino County Land Use Services, Building & Safety, since the community is unincorporated. WVWD lists its emergency services at (909) 875-1804, option 7.
