Changing a leaking tap on my central heating oil tank

    When the oil boiler was serviced the engineer found that the isolation valve (tap) had a small leak when it was turned off. Thankfully it did not leak when it was turned on for normal use. He stated that I should get it changed before the boiler is serviced next year, but suggested I wait until the tank was nearly empty before doing so.
    Can someone recommend someone who can do this job for me. I live between Bury St. Edmunds and Diss.
    Any help or guidance would be very much appreciated.

    Easy enough to do it yourself,if your confident , I had leaking isolation valve at a previous place that had oil tank.
    Cost me about £15 for the valve, took about 30 minutes to change, did have to jack up the tank so any remaining oil went to the back.

    A quick google fines this.

    Hi Kiab, Thank you for responding. I was under the impression that I would have to get the oil that remained in the tank pumped into a different copntainer before I could take the faulty tap off.
    I will wait until the tank is nearly empty, then I will try to change the tap myself, after jacking up the front of the tank, as you have suggested. I will let you know how I get on.
    Wishing you a Merry Xmas. Len Powell.

    All depend how low you run the tank, I was lucky managed to nearly empty my tank, so only needed to raise it about 6", any higher & I risked it sliding off it's base.
    If tank had been fuller then I would have pumped so much to another container.

    Hi Kiab, I still have close to 400 litres in the tank so I will wait until it has reduced to a manageable level before I attempt to change the tap. I will try to get a replacement tap from the company that manufactured the tank then hopefully there will be no problem with replacing it. Any advice on what if anything I should use to seal the joints?
    Thanks for your interest and help.
    Len Powell.

    Some years since I did it, I just used PTFE tape for the tank connection, .
    I don't think I used anything for the compression fitting, can't remember, just don't over tighten it.
    A quick google suggest NO SEALANT on copper compression fittings for domestic oil lines.

    Hi Kiab, Thanks again for your interest and help. My Watchmaster shows that I still have more than three hundred litres in the tank, so I will not attempt to do any more until it has reduced ssignificantly.
    Merry Xmas and a Happy New Year. Len Powell.
