    Joist Strengthening 1860's house.

    Thanks Guys. The 7x2's have arrived today, so i'm going to sister the old joists initially where the two tenon joints are first and take it from there. A couple of questions i have:- 1. I'm using M12 threaded rod with 50mm Dogtooth connectors with 50mm square washers - what is the...

    Joist Strengthening 1860's house.

    Hi Ree, The RSJ I believe was installed in the late 70's early 80's. The wall above the RSJ goes up to roof and does provide support for the large Victorian purlins in the loft space. The house is stone built and was 3 cottages in its early life before being made into one house. The floor...

    Joist Strengthening 1860's house.

    Thanks Victorian! As the ceiling is out of level by 3inches (with some joists not level with each other) I was considering using 7x2's to sister the joists with M12 bolts and dog tooth connectors to create a new ceiling level with the added bonus of adding strength to the 5x3's. (Not a true...

    Joist Strengthening 1860's house.

    Guys, I'm looking to strengthen the floor joist in my 1860's house. The timbers vary between 5 and 5 3/4 inch depth and 3 inches wide. The bedroom floors on either side of the RSJ are very bouncy, hence I dropped all the plasterboard to expose the joists to investigate. Span is 3.7m on one...

    Vaillant VCW 20/1 T3 - DHW ok , No CH

    HI, Just been to look at the above boiler to find the boiler cycling when calling for CH. Overheat stat kicks in until cooled then restarts again. No heat out of the CH flow pipe. Is this a Wax Stat at fault?? Also, I've got a dodgy copy of the manual in PDF that not really readable in...

    Puma 80 - Keeps blowing off the CH water!!

    Cheers guys, Good couple of things for me to check now. I must say I didn't check if water was pushed out the PRV when pumping up the Expansion Vessel,although I did leave the PRV in the open postition whilst pumping it! I'll try it tomorrow and report back. Thanks once again, Matt

    Puma 80 - Keeps blowing off the CH water!!

    Hi kev, Cheers for the reply. Have checked that air came out of the vessel - so I assume it's ok. Also checked the pressure using tyre pressure gauge to make sure it hasn't dropped - it's still around 15psi. As to the pipe connecting the expansion vessel I haven't checked that yet - do...

    Baxi Genesis 80 - New Diverter Valve - still faulty!

    You are right.....it is calling for DHW- Intermittently!! Flow switch occasionally reads almost open circuit when the hot water tap is off..just not completely O/C. It must be just enough resistance to fool the electronics. Going to pick up a new switch tomorrow and try it. Flamin thing...

    Baxi Genesis 80 - New Diverter Valve - still faulty!

    Hi, I've jsut replaced the diverter valve on this combi with a new one. All was fine for a few hours, but now it just comes on for 10 secs that turns off. Checked the Heating Flow pipe out of the heat exchanger - red hot! Checked the pipe after the valve - still cold! Looks like its still...
