    Double garage flat roof repairs contd...

    Thanks to all who have offered advice already. I'm getting conflicting views about deck material; some say 18mm OSB3 is fine others say where the underside is exposed to garage type atmosphere that OSB3 is definitely not to be recommended. Instead one should use exterior WBP (presumably still...

    Double garage flat roof repairs

    I have a double garage about 5x2.7m in need of repair. I'm keen to avoid a complete reroof if possible so plan to redo about half which will more than cover all of the failed areas. I want to do a sound and reasonably long lasting job but as economically as possible. I need to strip the deck off...

    How to re-prime Worcester Danesmoor 20/25 oil system?

    Hi Mandate. More or less up and running. It wasn't the end of the story though. I located excellent chap in Worcester and took whole burner to him to fit new Danfoss pump and set up everything. However, discovered the motor bearings dodgey and were intermittently seizing so easy to miss the...

    How to re-prime Worcester Danesmoor 20/25 oil system?

    Thanks Mandate. I'll have look at the motor tomorrow. I'll check bearings, coupling etc. If it needs replacing I'll have to pin down more accurately exactly which it is. I think you are saying it would be the same as for D42? The burner is a Selectos D11034/02/85/359760 if that helps (looks like...

    How to re-prime Worcester Danesmoor 20/25 oil system?

    Many thanks APHS. Spot on I'm sure, ie that the pump is dry as I had emptied ALL the oil lines as matter of deliberate overkill as I wanted to be absolutely sure there could be no dirt or water anywhere. I've printed a copy of the priming regime you recommended and will go forth try again. Very...

    How to re-prime Worcester Danesmoor 20/25 oil system?

    Hi all you guys who were so helpful yesterday. Armed with your ideas I first took the opportunity of the empty oil feed line to install a tee and stop tap at the tank end. Even if I don't need it now I know I'll kick myself for not doing it at some point in the future. I then, lo and behold...

    Re-roofing double garage flat roof. Brain storming!

    I have a solidly built blockwork double garage 5x6m (build by a previous occupant) incorporating two massive 10"x5" RSJs, one across the opening the other across centre. Joists are 115x50 softwood at 600 centres and all sound. Unfortunately the the roof boards and felting are anything but...

    How to re-prime Worcester Danesmoor 20/25 oil system?

    Wow, many thanks to all of you for the incredibly helpful suggestions. too many to thank you all in person. I especially like your suggestion 'Mandate' about fitting a tee at the tank so a false head of oil can be created, plus by-passing the control box to avoid lockout. Brilliantly simple and...

    How to re-prime Worcester Danesmoor 20/25 oil system?

    Thanks all of you for your suggestions... Tony; I'll try filling the chamber. Sounds sensible. Holty of Cornwall; no, tiger loop isn't new. It has been working fine for years. Not sure about 'circle' type shut off valve but oil is definitely flowing. Mandate; I'll try the 12mm hex nut...
