Hi My sons existing system uses a Tempus 7 from about the mid nineties vintage. Seems to work ok when set to timed intervals a day He has tried to set it to Once a Day but now heating is on at all times. Im suggesting that there will be a sequence for the ON OFF time settings, but i cant...

Hi In an existing kitchen is the sink unit in 1000mm base unit There is a 1 1/2 sink in it with the correct trap kit with it. Sink is located at left hand end of unit There is a spout to connect a washing machine to the trap kit. The washing machine can only be installed to the right of the...

Re worked the pipes I used the boss pipe as suggested although I had to lower it by 110mm I cut down the removed stack pipe and made a short extension I inserted it between the toilet branch and the new boss stack Much better job and peace of mind Cheers

Thanks John D I did think that may be the case I’ll get around it from within the bathroom.

Cheers for reply I’ll measure up etc The position of the connection is important above ceiling is important obviously for the fall I can try and use boss as suggested but it has to connect directly to the branch above for the toilet. This in turn puts the boss connection in a fixed height...

Hi Advice please? I’ve had a continual problem with a bath to soil stack leak 40mm Waste is running beneath floor to an internal stack and connected via a strap on boss. Despite best efforts it leaks between adapter flange and soil pipe I’ve now damaged soil pipe and will replace the section...

Thanks I can see insulation cut to shape to fit recesses, do you mean a further layer of insulation over the top of the frames and then plasterboard? Not sure if I can do that due to possibly covering window frames

Thanks Woody. So if I understand correctly I can do this from inside, hopefully without disturbing outside render? Construction is similar to wooden framed bay window? Cheers

When all else fails :) a lot. Thanks for your patience I’ll try it in the morning And I’ll still try and calculate it cos I’m stubborn and I like problems to sort!(y)

Seriously please! The walls of the dormer window are literally running wet in the morning Tried leaving window and door open without improvement Using a de-humidifier helps. Not sure how the wall of the window are constructed but does anyone know what needs to be done to insulate them?

Thanks Terry Now I’m getting confused But if I have read it correctly it confirms that I should be using CP2 with ABV. OR use Proprtional Control and a fixed bypass? Boiler min flow is 4.5 l/m Can you take an educated stab at ABV setting based on CP2 pump setting? Then I can start on...

We tried lots of different ways before we changed the ABV When it had been changed we took a long time bleeding , running system cold then bled again Turned off ground floor rads Turned on up rads and heated Turned lockshields down on up rads to about 30% open Then turned on ground floor 1 at a...

Thanks Terry L I’ve got manual for all bits now ( I think) I’ll have a stab at working it out. If ok with you I’ll ask you to check my theory before I apply setting? Cheers

Thanks for that. It was from a downloaded manual direct from potterton It’s been wrong since day 1:(

Hi Hopefully title says it all. Has anyone had issues with condensation in a dormer window and found a good cure for it. Cheers

Hi Terry were there supposed to be attachments with this message? (These graphs are in the instructions for your boiler and pump) thanks

Hi I've found some info on the boiler and manual says min flow to be maintained is maintain a minimum flow through the boiler of 4.5 litres/mm (1 gal/mm) Is this correct? i thought it would be expressed as litres/minute

Thanks for that info. There 2 other settings I think CP1 CP2 ? Would these be more suitable as the pressure is supposed to be more constant even if load changes? If not, I could use III. The original Grundfos 15-60 was set to this Cheers
