I actua;lly managed to get the box etc very cheap. Haggles in B and Q due to packaging and a small black mark and it being the only one, The fact I drove "12" miles one way lol.
The rest was a little bit of hose for free, and a few fittings. Two plastic washers to let it mount wither side of box, as when the hose was in, the threaded screw would not but up to it.
Spent £13 In B and Q today, Pump ad controller cost about £170 from gardiners.
Box and fittings would usually be about £30 tops.
But alows you to buy bit by bit if not in a rush etc. And not have to sit in and listen to my girlfrien whineing that I havent been onto the estate agents lol.
