Younger generation, something wants making/repairing/doing get a man in to sort it :-)

Could be a sticking micro switch, gently tap the unit with a piece of wood a few times and see if that actuates the motor

Further to the above if you are au fait with spreadsheets I have put one together based on the examples around page 16 to determine wall thicknesses required based on various parameters depending which ones are chosen. Unfortunately I can only put up a print of the spreadsheet so the sheet...

Had a similar problem with mine due to foundations being a couple of rows laid at surface level, fortunately mortar was softer than bricks so no cracking as such. A bit of TLC to sort.

A little light reading , the examples around page 16 will give you a view on wall thicknesses although your proposals are slightly off the beaten track and foundation design are in a different league https://www.brick.org.uk/uploads/downloads/s-design-of-brickwork-retaining-walls.pdf

As well as the thickness, height,density of the wall there is also soil properties of soil be retained and bearing capacity and size of foundation to be considered which I should imagine rule of thumb gives scant regard as does your builder by the sounds of it. "We have always done it like this...

Don't know what the design parameters were at the time of build but todays timbers are designed for snow loading of 75kg/m2 , changing from tiles to concrete can increase roof loading by 10 to 35kg so possibly roof is structurally OK at the moment but just hope global warming keeps the snow at...

Dittto, interesting to note that you have different boiler output options for CH and HW

Or the bolts failed in shear due to the friction element of the design not coming into play? Perhaps sagged means dropped?

And if that does not work open the stopcock to fully open and see if that stops the drip. If that does not work then undo the top nut, slide the body up the spindle and then either wrap 6 turns of PTFE loosely around the spindle and then retighten the top nut forcing the PTFE down into the...

Why do you think a washer in your stop valve causes water hammer
