Here is an extremely rough sketch of the way I have it set up.. It keeps on pushing water into the second tank when the main tanks pump turns off.. Can anyone tell me an easy way of stopping it from syphoning i.e something I can put on the pipe within the main tank just before it comes...

the outlet pipe from the main tank is about 1.5 foot above the inlet on the second tank and well above the pump in the main tank..do you have any links to some anti syphon vales? Thanks

Hi all, I have a main tank with a pump in it pumping into a smaller tank. When the pump in the main tank turns off it continues to syphon down into the smaller tank. I am using a float switch system that I would like to turn on the pump within the main tank when the second tanks level gets...

Very good idea... The trouble is the plastic sheet thats glued to the bottom of the tank can never come off again...melting the hex nuts into the bottom of the sheet might work though so if the pumps ever need replacing or cleaning I could screw back down into them. It would be a lot...

A google suggests the one you intend buying (a) comes with a 1/4" plug adapter, and (b) runs off a watch battery, which may need rather frequent changing. The guy from tech support seems to think one battery will last for 1000 hours....I think this is a bit adventurous..but at 76p a battery...

Thanks for your reply.... The CCTV mics ive seen dont look like they will pick up a good all around signal. So it would seem I need to use the pre amp and things are getting complicated..As I see it to use the amp I will need to get a 1/4 inch jack - 3.5mm jack converter...

Hi, I installed the whole lot from new i.e wall lights, switches etc.... Im actually an NIC Approved contractor but have never known dimmers to flicker like this. As I said in my last post its a 60-250W dimmer with 60W lamps on and was wondering if anyone has ever come across this before I go...

Hi all, I recently installed a 3 gang MEM dimmer switch rated at 60W - 250W in a customers house. The customer bought the dimmer switch from B&Q. Its rated 60-250W for each gang of the switch. When I first fitted it sometimes the 60W wall lights would flicker on and off then eventually stop...

Hi all, Im going to view a flat tomorrow that is double glazed but the old wooden window frames and wooden window sills have been left in. It was an old lady who lived in the house who is now in a home so theres every chance she has been ripped off by a window fitter who has charged her for...
