Mmmm either your incoming main pressure is extremely low - your pressure gauge is giving a false reading - or the double check valve is stuck. Is the loop as I described - ie a chromed breaided hose connecting onto two chrome taps with blue or black plastic heads?

Standard grunny should suffice.

At the top (chrome puch button) the buttons themselves come out to reveal a screw underneath. You can feel some resistance because indeed - there are little catches on the underside. If you can use a very fine, but longish screwdriver - you should be able to pop them up without damage...

The ranco stat that sits at the top of the boiler may have gone out of tollerance or the max burner pressure may be set too high, or there may be sludge in the system. You need a competant gas safe engineer to diagnose. Allan

It sounds like you have a problem with your expansion vessel and pressure relief valve. Do a search on here and you will find lots and lots on that very subject. Allan

The safest and corrct method would be to drain down. you should have no problems re-filling because it is a sealed system. Hope you read my previous post in this thread? Allan

It may be important to identify where to connect into the existing pipework - say for example if the boiler is responsible for heating a thermal store, or an indirect cylinder. Just tee'ing in anywhere could adversely affect how your system works. More info on the system is needed. If you...

Yes it can unfortunately. The expansion vessel may just need re-charging with a foot pump - or it might be knachered! You need a good heating engineer to identify which. Al

The charging link for your boiler was an optional extra and might not have been installed. It sounds as if you may have a filling loop instead. This is a braided hose connecting one pipe ( CH return) to another pipe (cold water inlet) Sometimes these filling loops have two taps that you...

Sounds like the gas valve is kapput! This boiler has a positive air combustion chamber and is potentially dangerous if the repair is not carried out by a competent Gas Safe engineer. Al

Does anyone have a link for a bolt on boss for 4 inch CI? I have checked out treads from the past but the links on there are now dead. Thanks men :)

You will almost deffo find the supplies reversed fella. Most of the time it is easy to callibrate without MI's. Just move up to the red stop button and measure to 38 degrees c. if there isn't a stop button (anti scald) then set max to about 43 degrees c - pos less if children are using...

Fitz - I am in Widnes and work all over Merseyside if that is any benefit to you. In the meantime - if the shower valve is a lever type, by which I mean a handle that you hold and move right or left to adjust temp? - then you should have cold when moving the lever over to the right1 Maybe...

no no budy exactly the same pressure - the hot from combi is also from the main. The only difference is the fow rate between the cold and hot - but pressure is the same. will most likely be the shower valve - maybe you have indifferent pressure reducers in the supply pipework - or...

You shouldn't need any valve fella - combi boilers provide ballanced pressure between hot and cold. You probably need to callibrate the shower valve. Can email tomorrow if you have your email addy in your profile. Al

No there isn't full ramp when you turn tap on. I have MI's if you want em

:D Nice one Cyril

Are you vent and cold feed connected into your primaries? Where have you installed the Valve? You may have made the system dangerous. AL

Fixed this ages ago but forgot to update. Replaced dv and flushed ch flow and return with mains pressure. Connected back up and all tickety boo.
