Always-on operation

UV is continuous — lamp on 24/7. ~30 W standby draw, about £65/year electricity. Switching the lamp off and on shortens its life and risks contamination, so the system is designed to run permanently.

Power LED

Green LED on the ballast box confirms the lamp is energised. Mounted at eye level in the plant room or cupboard — visible without opening anything. The one indicator you check during the year.

Lamp-failure alarm

Audible buzzer plus red LED if the lamp fails or the ballast loses contact. We're notified automatically via the service plan; you ring us, we replace the lamp. The alarm doesn't stop water flow — it just tells you treatment isn't happening.

Inlet isolator

Full-bore ball valve upstream of the reactor. Engineer’s on/off for service. Use it together with the outlet isolator to drop the reactor without losing supply to the house.

Outlet isolator

Matching ball valve downstream. With both isolators closed and the bypass opened, the rest of the house still has water during a lamp swap.

Bypass valve

Pipe loop around the reactor, with a manual valve. Engineer opens it to keep water running to the property during service. Closed in normal use — everything routes through the reactor.

Drain valve

Small drain on the reactor low point. Used to flush the chamber after a lamp swap, before bringing the system back online.

Pre-filter housing

Clear-bowl housing on the inlet side, with a manual relief button on top. Press to drop the bowl pressure before opening for a cartridge change. The only part you might touch yourself between visits.

Stainless reactor chamber

AISI 304 stainless steel tube, electropolished interior. Engineered flow path forces every drop of water past the lamp. 10-year design life, replaceable end-of-life. The body of the system.

UV-C lamp

Low-pressure mercury lamp emitting at 254 nm — the wavelength most damaging to microbial DNA. 9,000-hour rated life. Replaced annually as part of the standard service. The only routinely-replaced part inside the reactor.

Quartz sleeve

Clear quartz tube around the lamp keeps it dry while letting UV-C pass through into the water. Inspected and wiped annually with the lamp change. Replaced if scaled or fouled.

Electronic ballast

Wall-mounted control box delivers regulated power to the lamp and houses the LED indicators. CE-marked. Auto-restart after power cuts; lamp-failure alarm.

Pre-filter housing

10-inch standard cartridge housing fitted upstream of the reactor. Holds the sediment cartridge that protects UV effectiveness.

5-micron pre-filter

Polypropylene sediment cartridge. Catches anything that could shadow pathogens from the lamp. Replaced every 6–12 months depending on water quality. Cheap and easy to swap.

Inlet/outlet fittings

1" BSP male threaded connections. Industry-standard plumbing fittings — integrates with any UK domestic mains. Stainless steel construction.

Wall mounting bracket

Pre-drilled stainless steel bracket fixes the reactor horizontally or vertically to the wall. Typically mounted on the wall above where the rising main enters the property.

Invisible operation

Whole-house UV sits on the rising main, usually in a plant room, garage or under-stairs cupboard. You don’t see it, you don’t touch it. Water just becomes pathogen-free at every tap.

No taste change

UV kills with light, not chemistry. Nothing added, nothing removed except the pathogens. Minerals untouched, chlorine (if your supply has any) untouched, taste exactly the same as before.

Every tap, all day

Drinking, cooking, brushing teeth, washing salad, filling the bath. All your water is the safe water — not just one dedicated kitchen tap. Matters most for well-fed and cistern-fed properties.

Power-on continuously

Lamp runs 24/7. ~30 W standby, around £65/year in electricity. Cycling the lamp on/off shortens its life dramatically — the system is designed to run permanently.

Annual lamp swap

Lamp rated 9,000 hours — about 12 months continuous. Replaced on the annual service visit. Quartz sleeve inspected and wiped at the same time. The kit is around £65 plus the visit.

Pre-filter swap

Sediment cartridge replaced every 6–12 months depending on water quality. Quick visual check — if the cartridge has turned brown, it’s done its job. DIY in 5 minutes or part of the annual visit.

Quartz sleeve clean

Every 12 months the quartz sleeve gets wiped to remove any film that could shadow the UV. Done as part of the lamp swap. Replaced outright if scale or biofilm has fixed to the surface.

2-yr warranty

Full 2-year manufacturer warranty on the reactor and ballast. Stainless chamber rated 10-year design life. CleverBloom handles any claim direct with Ecosoft.
