I have a Sime Super 90 which is giving neither hot water on demand nor central heating.My fault finding guide suggests the pump is not working and there is no movement detected.Either the pump needs replacing or the power supply to the pump is faulty.The boiler is over 10 years old and a new...

Thanks barry!I have tried to reset heat stat but already depressed.Also there is ample pressure so it looks like a new pump needed

I have the script here and its reads pump-fan -ignition so it points to the pump does'nt it.What do you think?

I have had a second inspection and the pump is not running.Am I right to believe the pump is activated before the fan?If this is the case it suggests the pump is faulty.

NO the fan does not run.As the boiler is over 10 years old then the fan may well feel tired;thanks for the quick reply Kev

The boiler will not fire up either for DHW or CH.The pump does not start when CH is on so I presume this may need to be replaced.The fault finding guide suggests this.However on the other hand it may be a new PCB. The only sign of life is the green neon and the click of the microswitch when the...

Thanks for the correction-I meant 19mm down gravel

I need to mix 2.5 cubic metres concrete using a 3:2:1 mix I plan to order 2 tonnes ballast(correction-gravel), 1.5 tonne sand( slightly excess) and 24 X 25kg bags Portland cement. Does this sound approximately correct. I dont mind if I over order the ballast and sand

A mate mentioned a knife or blade used to cut pasted wallpaper without snagging it.Its a new one on me but sounds ideal.Can anyone advise?

Thanks for your helpful comment

The top of the earthenware section is vertical and was attached (until 10 years ago) to an asbestos stack.When this was was removed the builder chipped it out and damaged the clay section .It needs to be but straight to permit the use of a clay/plastic adaptor.As the clay section is likely to be...

Thanks superduper for your advice.I will order the servicing kit for my friendly fiiter to use.We have two good parts stockists here in Sheffield-do you have a parts number? Thanks again for your prompt reply

I have a Simi super 90 which has been excellent-two minor repairs in 10 years.The central heating is fine but the DHW is lukewarm when drawn from a boiler on winter setting ie when centralheating operating.When heating off the boiler does not fire up.I imagine there is a fault with the divertor...

I need some approx 1.5 metres in length with 13mm section.Where is best place to buy?Am in Sheffield so should be plenty available.

Sorry to not make myself clear.The siphon supplied with the toilet is a dual flush with a push mechanism housed in the cistern lid.I bought a better siphon but the instructions show the mechanism is housed in the main cistern body where the handle would go on a traditional system.Can I fit this...

Can anyone confirm my suspicion?

Just bought an upgrade siphon with button on side for variflush.Existing cistern has top button.Can I use the new one as a top flush rather than side flush?

Thanks so much for helpful comment;one more drain down and done I hope. :D

I have fitted a cc toilet in my mothers house-the cistern split last week.I have worked out that there is no leak from the cistern to the pan from the syphon nut.There is a small escape upon flushing to the left hand side.The cistern is level horizontally.I replaced the grommet supplied with a...
