Discuss Boulter Camray 5 leaking filling loop and pressure rise in the Oil and Solid Fuel Forum area at UKPlumbersForums.co.uk.

    Hi guys,

    I have a Boulter Camray 5 combination oil boiler (quite old I think).

    [​IMG]

    Recently I bled the radiators and then the next day was woken by a horrible noise from the boiler. I think the pressure drop caused it(?). Anyway, I rectified the issue by using the filling loop to restore pressure.

    However, now the pressure keeps rising when the heating is on (doesn't seem to rise when it is off). I have observed the slow leaks from both valves of the filling loop. This leads me to believe that the valves are passing and increasing pressure in the boiler? I was wandering if anyone could talk me through replacing the filling loop, I'm particularly interested in whether or not I need to depressurise the system (and how), and if after turning off the stopcock I should run a kitchen tap to dry?

    The filling loop is on the top of the boiler on these, and I am in a bungalow so I am hoping that not too much water will come out once I remove the filling loop, but I am concerned about that. Again, any help would be appreciated in this area.

    Finally, the expansion vessel (dated 2012 so may have been replaced), some liquid came from the bicycle valve when I tested it. I have read that if any water at all comes from it then the diaphragm can be broken, and that having the vessel full of water can also lead to rising pressures.

    I think a new boiler is on the cards soon but if I can buy some time until my funds build sufficiently it would be a big help!

    Many thanks in advance.

    Boulter was bought out by Worcester some years ago. Boiler obsolete. Sounds as if you'd be better off with a competent engineer helping you out to tie this one over.

    Easy repair for a competent engineer. Decent boiler the camray 5. Stick with it as long as you can. All the new oil combi's are poor in comparison.
    Look at heat only and unvented cylinder if space and water pressures/flow allow.

    Agree with SimonG, easy fix but needs doing properly. Regarding the vessel, you can get a little condensation spit out when depressing the schrader valve, but if a lot of water pours out then a new one is needed, however if you let too much pressure out then it's pressure and system pressure would need checking and resetting, which a competent engineer would be more than capable of.
