Exchanged the pressure relief value today but now when we put the heating on the pressure won't stop rising and boiler is shut down by safety switch. Pressure stays constant when heating off so have hot water but as soon as heating goes on it just shuts down. Any ideas please.
 
Possibly the high pressure switch is playing up.......usually due to PRV being over tightened...
Dependant on PRV termination it's not uncommon to find low pressure switch shutting boiler down on both HW and heating...
Is the condensate discharge pipe white or black???
 
Where is the condensation pipe. Hubby not a plumber just knew how to change the bit he did. Which stopped the pressure dropping and thought was solved until this started happening. What is the PRV please?
