    Hi All. New to the forum.
    I rent a s/d farm cottage. The landlord had a bunch (of cowboys) call round to cavity fill and insulate the loft. They did the CF but the head bloke (white shirt) wouldn't go up the loft as he was frightened of spiders.
    The two lads that followed wouldn't lay the insulation because I have an asbestos cold tank and C/H header tank. End of that then. The landlord went along with this because it was free. The slate roof has no felt so I have the best loft in North Essex. A million flies can't all be wrong. Ha Ha!?

    As another winter approaches I'm thinking could I do this myself ? C/W tank has no proper lid and the C/H header is joined onto it by an overflow, in theory if the header level goes up Fernox (???) could enter the cold tank, the one I brush my teeth from; not to mention the dead flies.
    I'm ok at DIY, so is this all possible ? Wrap old tanks and move to corner of loft. Fit plastic (Screwfix) tanks. Insulate loft. Don't tell the landlord so he doesn't put the rent up, again.
    Any help and advice most welcome.

    Sounds like a plan.

    Basin & sink will be fed from cold water mains, your teeth are safe.

    Should be, but they often aren't (the taps, not the teeth!)

    Many years ago I fitted a shower, nothing fancy, above the bath. I tee'd into the cold water tank ballcock feed in the loft so this is the only mains water in the bathroom.
    The house was a 3 bed (45 years ago) but the smallest bedroom was converted into a bathroom as this was a cheap option.
    I've often thought of brushing my teeth in the shower. :D

    The asbestos tanks make nice planters, i've got 4 in the garden, fill the holes with cement and give the whole thing a coat of sandtex paint. A lot of people don't realise the hazards, or lack thereof when handling asbestos cement, so you get these eejits who won't go into a loft because of an asbestos tank, although they probably walked around in a wholesalers warehouse with an asbestos cement roof. Unless you cut it or seriously abraid it the fibres stay put within their cement binder.

    Thanks for the gardening suggestion but as I have no intension of knocking a hole in the roof and the loft trapdoor is 650mm square if it comes out it will be in pieces.
    Open to suggestions for this. Water spray on a hand saw maybe ???

    I would leave it up there, push it into a corner, if you really need to break it up wrap it in plastic and break it with a lump hammer - sawing releases a lot of fibres so is a bad idea!

    The house (S/D) has a hip roof so the area with the most head room is the spot where the old tank is, and the new tank will be, against the chimney (party wall).
    I will build a raised pallet to put the asbestos tank on so that the insulation can go under at the correct thickness.

    Thanks for all the replies.

    What are the dimensions of the old cold water tank?
    650mm square trap door opening is fairly large (actually larger than most)
    The tanks can usually be taken out end ways if the dimensions allow.
    You probably still qualify for a grant for loft installation, so if I were you I wouldn’t install or pay for the landlords loft insulation.

    Off to screwfix to buy some disposable masks. I will get up the loft this afternoon and measure up.

    Well that explains the 650 square loft hatch. The tank is 630 x 640 top opening, and a height of 640mm. The sides slope in slightly, presumably they were made in a mould and this aided release.
    That makes the job easier. :)
    I see Screwfix do a 1185 x 503 x 503 kit for £135.99 so that would do nicely.

    Yep they were made in a two part mould - when shifting it beware they are very heavy, one man at the bottom and one at the top is favourite
