POSSIBLE CAuSE

SOLuTION

Water escaping from the case

Compression fitting on hot - draw off not sealing

Check/remake joint with sealing paste

Cold water at Hot taps

direct - immersion heater not switched on or cutout has triggered

Check / reset

Indirect - boiler not working

Check boiler - consult boiler manufacturers' instructions

Indirect - motorised valve fault

Check plumbing / wiring to motorised valve

Indirect - cutout in dual stat has operated

Reset and investigate cause

Water discharges from expansion relief

valve

If continual - pressure reducing valve ( part of inlet control set) may

not be operating correctly

Check outlet pressure from inlet control set is 3 bar.

If continual - expansion relief valve seat may be damaged

Remove cartridge - check seat and renew if necessary

If intermittent - expansion vessel charge may have reduced / bladder

perished

Check pressure in expansion vessel. Recharge to 3 bar if necessary. If

bladder perished replace vessel.

unit it being back pressurised

With cylinder cold check pressure in cylinder. If this is the same as

the incoming mains pressure then you are getting backfeed. Install a

balanced cold supply (see page 6)

Water discharges from temperature &.

pressure relief valve

unit has overheated - thermal controls have failed

"Switch off power to boiler and immersion heaters.

Leave water supply on. Wait until discharge stops.

Isolate water supply and replace if faulty"

Milky / cloudy water

Oxygenated water

Water from any pressurised system will release oxygen bubbles when

flowing. The bubbles will settle out.

No hot water flow

Cold main off

Check and open stopcock

Strainer blocked in pressure reducing valve

Isolate water supply and clean

Inlet control set may be fitted incorrectly

Check and refit as required

Noise during hot water draw-off

-typically worse in the morning.

Loose airing cupboard pipework

Install extra clips

Hot or warm water from cold tap

If tap runs cold after a minute or so the pipe is picking up heat from
