Sorry - very last minute, but my builders are installing final steps up to the house tomorrow, and I've got to install pipework to enable the pond next to the steps to be filtered properly. As in picture below ... pond will be one side of steps, filter the other. I'm guessing the pipes will run underneath 2nd tread down. Pond is 400mm deep ... so should the pipes enter it half way up ... or right at the bottom ... or does it not really matter? But got ZERO idea what is needed here ... 15mm? 22mm? Anyone with experience of this kind of thing I would love to hear from - much appreciated. Also ... will it need any protection against frost etc. do you think?
Any other top tips very gratefully received. We just want a very still, dark body of water ... will probably fibreglass the base etc.
Thanks all - need to scoot off to Travis Perkins first thing! Don't want to have to dig the steps up later etc.
EDIT: sorry - should have pointed out if not clear ... pond is about 5,100 litres of water (about 7.15m x 1.78m x 0.4m) Will this mean a wider diameter pipe I wonder?
