    Circular TCT Blade question?

    I am using an Erbauer 2000W 255mm sliding mitre saw to cut old timber for my wood burning stove. I have got into a routine and it works very well. The only problem is that the saw blade can lose teeth when hitting a nail (which I try to avoid but sometimes can't spot them all). I bought the...

    Does every sewer connection require an inspection chamber?

    In a combined system, if there is a drain with one toilet connected to the sewer and this has an inspection chamber, does another another drain with a second toilet, connected to the sewer a few feet away, have to have it's own inspection chamber? In other words, if you have two connections to...

    Can I cap a disused soil pipe?

    Thanks Sooey. A further question - what are the chances of my building insurance paying out on the problem described in my original post? i.e. possibly lining the leaking pipe?

    Can I cap a disused soil pipe?

    We have 2 toilets feeding into an old foul drain branch and 1 toilet feeding into a newer branch. The underground run of the old pipe has developed a leak and we are getting some foul water in the void under the house. I plan to divert the downpipe with the 2 toilets to the new branch and so...

    Where / How do you buy rebar??

    I need a piece of rebar mesh approx 10ft x 4ft - it's for a concrete base that I am building. Where can the DIYer obtain this and how do you get the size you want? I live near Manchester, so have access to the usual outlets.

    Well, I am an electrical engineer so suppose I should be a bit more savvy than Joe Public.

    Glow Worm Ultracom - second diagnostic level password???

    Wow - talk about great minds - I already have the HW at 45deg, as that happens to give a perfect shower temp. I have the CH at 62deg, except in very cold weather. Very similar figures to your suggestion :)

    I am certainly happy with it - summer quarter gas bill was £26 for hot water and cooking :D I can live with it as it stands - suppose I am looking for perfection

    Glow Worm Ultracom - second diagnostic level password???

    I have preheat disabled. It still behaves differently when firing after HW demand, as I mentioned above. In that case it fires with only "one flame" showing on the LCD display. There is no problem then.

    Tony - will check when the heating decides to come on - boiler cold at the moment, as quite warm outside! Chris - what a cynic but I tend to agree with you!

    Glow Worm Ultracom - second diagnostic level password???

    Interesting theory, Tony. You can monitor the flow and return temps via the LCD display. The flow ramps up quickly and the return is quite slow to increase. I may as well try a technical question to Glow Worm, via their website facility.

    Glow Worm Ultracom - second diagnostic level password???

    d1 is water pump overun time for CH mode d0 is heating part load. When the boiler comes back after HW demand, it does indeed start low and ramp up slowly. Unfortunately, when it comes back in CH mode, it starts at about 60% of max. That is why I was asking if the level 2 menu would allow...

    Glow Worm Ultracom - second diagnostic level password???

    Thanks to all for the further replies. I did range rate the boiler, as suggested by Agile (with the settings provided by dangermouse). It did not help, as however low you set the max output (and I tried it at minimum) the boiler still fires with "three flames" showing in the LCD display, when...

    Glow Worm Ultracom - second diagnostic level password???

    Dangermouse - I think I could solve my problem by increasing the pump pre-run time, i.e. before the boiler fires. Do you know if this is adjustable from the l2 menu and, if so, which parameter?

    Which Boiler–Vaillant, Glow-Worm, Worcester? Fit Magnaclean?

    Magnaclean - yes, yes, yes! When my installer fitted the Ultracom to my old system he insisted on a power flush first and fitting of a Magnaclean. I have cleaned it out a couple of times and all I can say is that I am glad all the metal muck that it picks up is not getting into my heat...
