Woke up this morning to a cold house and no hot water. Looked at the boiler and there is a light flashing showing it has low presure. This has happened once before and you have to open a tap on the underside of the boiler unit to presumably let more water into the system?? Tried it today though and nothing happened as in you cant feel anything flowing as you open the tap.

Can any plummers advise me as to what this might be before I call someone out.

Cheers for any help.

 

is there more than one tap, depending on the loop there may be one on either side of the flexy

 

Yes, mine has 2 taps.

How often are you filling it? Maybe indicative of a problem?

 

Yes, there may be a valve isolating the flushing loop because they can pass and overfill the system. When you fill it take it up to 1.5bar on the gauge. Check all your rads for leaks too as there is a reason why it has lost pressure.

 

This is the 2nd time it has happened in 4 years. last time i just opened the plastic valve and the presure seemed to equalize. This time nothing happens. im cold

 

Either you have another valve to open or you have a Non return valve thats possibly jammed

 

Just looked, no taps only this plastic type valve which you can screw in and out. Nothing happens though.

There was supposed to be a Plummer coming round at 6pm but they havnt showed. Just what I need when im filthy from work and cant have a shower.

 

Picture of said hose?

.

 

Its not a hose. Its hard piped into the boiler in the housing

 

what boiler have you got?

is it just the heating or the hot water that's gone?

is there something else that might have tripped the system so that it's not starting to heat up?

etc?

 

Its a Glow worm 30cxi combi boiler. Needs to see 0.7 bar or it wont run. its sitting at 0.3 bar at the minute.

 

Fixed. Well for now anyways. Didi a bit of research and its a common problem on these boilers. Took the tap off and the bit inside that screws up to seal it off has broken off and it wouldnt let water flow. Need a new tap now.

 

Can anyone recommend a good company to get Glow Worm spares from as ill need a new tap.

 

Gloworm!
