    Diy wind powered water-pump

    What sort of head will the pump require - what is the height between the sea level (low tide) and the drying beds, is there a wall around them that the pipe would need to go over, is that the 1m or are they filled with water to a depth of 1M ? Does it matter how long it takes to fill each bed...

    DIY Draining down system

    As above, both sides are connected so as you drain the heating the hot water primary's will drain as well. I take it you have an F&E cistern in the loft, if you follow the 15mm cold feed pipe down it should connect into the return coming out of the cylinder or go all the way down to the boiler.

    DIYer - need help with toilet pipe air-valve install

    I am still concerned that you may not be venting the stack, can you get the vertical stack outside to vent correctly to atmosphere? Will this be the only vent on your drainage system? By Law the head of the run must be vented !!!

    DIYer - need help with toilet pipe air-valve install

    The bath connection is the main problem one for siphonage because of both the volume of water & how quickly it discharges. Not so with the shower because the water flow is much slower & there is normally water draining away slowly after the shower is off, this will refill a water trap even if...

    DIYer - need help with toilet pipe air-valve install

    No, you don't need & probably shouldn't have a "Durgo" on the main stack, can't terminate to atmosphere ? if it can then the loop is find but not essential it is more to try to anti the bath run so it will not self-syphon when discharged. Otherwise couldn't you run it separately along the eaves...

    Advice needed on DIY central heating plan

    I think it will be fine like that after all you have a PRV on the system & the pumps on the return, nothing else required. Begs the question what will the rest of the house be like (at least until the winter comes).

    This is the standard of a heating engineer today

    This is a classic & really does make me wonder!! Some of you might think I am over zealot when it comes to the correct level of training for the industry but this might give you an inkling why I am like I am. Just got of the phone an hour ago from one of our engineers he was booked for a...

    I am a BG customer (yer don't have a go) for both Gas & Electric & have Smart Meters, sad as I am I was intrigued to see that you can call up what you have used hour by hour for each day.

    DIY project may have been the wrong choice

    Hi So long as the water level in the small cistern on top of the cylinder (tank) is still higher than the hot water taps then it will work (don't go drilling anything). Most likely you have an air lock in the hot water pipework, taking it that all the valves are open!! Plumbers trick - use...
