Hi, I need to replace a two way 22mm motorised Zone valve as I have replaced the motor twice now and it has failed again so I’m assuming the valve is stiff for some reason. It’s the valve that allows CH water into the HW cylinder to heat it. Is there a truck to create an airlock so I don’t...

Hi I’m building a retaining wall in my garden. There are already similar walls in the garden that have been constructed from 140mm blocks laid flat and rendered with sand & cement. The walls have been in place for around 20 years and show no signs of cracking or movement. I have decided to...

Hi, I’m building a retaining wall using concrete blocks laid flat. Is there any reason why shouldn’t use 140mm blocks, just thinking as an amateur block layer it will mean fewer joints? Are 7NF blocks the standard I should be using? Thanks in advance. Jon

Thanks Ken I imagined the perforated pipe would run behind the length of the wall and the smaller diameter pipes would T into it and run at 90 degrees through the wall forming the weep holes, is that not right? Regards, Jon

Hi, I am laying a foundation for a garden wall and am mixing the concrete myself in a mixer. Do I have to fill the entire length of the foundation in one go whilst all the concrete is wet? If not, should I fill the whole trench in layers or fill to the top of the trench in sections? Hope that...

Hi, I have an oak staircase some of the balusters are loose and rattle. The gap on the loose ones is tiny, less than a millimetre on most. I want to avoid taking them out and refitting them. I could glue them at the bottom but this would be tricky at the top. Is there a trick to shimming...
