    Any heating engineers about?

    A relative has a heating oil tank that's just had 1000lts put in, but has noticed a sight drip from the main valve.
    It needs replacing, but this is very much the wrong time, so needs to be patched.

    Trouble is not a lot want to stick to kerosene even when it's wiped clean. Self amalgamating tape did a good
    job for a week, but that was optimistic seeing as rubber and kerosene are not a great mix.

    Seen similar that is dunked in water wraps around like cloth and goes hard in 20 mins, that might work. .

    All this will be replaced along with a new fuel line in the Summer, but for now any heating engineers got any ideas
    of what can be used?

    You can get fibreglass patches that react to UV and set in 10 mins.

    You can get a silicone based self amalgamating tape. Silweld or halfords sell it as fixx-it tape. Never used it

    Thank you Steve, helpful advice and according to the solvent list silicone will resist kerosene, so it should work.

    Have a genuine Merry Christmas

    When in Halfords ask what they have for repairing petrol tanks. There used to be a kind a of putty like substance was 20 years ago when I used it.

    Denso tape will do it or slow it for now or see if fibre fix have anything that will work in the area affected

    Also depending on valve and location of leak it may repairable in situ, e.g. stuffing gland on gate valve can usually be tightened.

    Thanks Jon, the cloth fibrefix that's soaked in water seemed to be the best option out of those two as it goes off in 20 mins
    once in place, but going with the silcone tape first as if this fails it will be easier to remove.

    It seems to be where the pipe goes into the valve which looks to be a mix of about 3 reducers.
    The pipe run goes underground for a run of about 10m and has a number of elbows that retrict flow.
    Soon as anytying is touched an air-lock forms and it's a bitch to get rid.

    I've nipped it up about as much as I dare, but not knowing the state of the valve or joints don't want
    to risk it until the 1000lts have run down, so hopefully can renew the lot from tank to boiler with a single
    clean line about March.
