Hello Lisa
Have a read of this post that I have found from Ray S in 2009
The rest of the thread is
here
The torbek side connection valve will only fit the cap of the 40litre aquaroll. You will find the float fits on a sort of spiral plastic rod, and you need to cut the top of this off, leaving the float on the shortest possible arm.Make a hole centrally in the cap and fasten the valve with the backnot supplied getting it a tight as you can. Before doing this, put the cap on the roll,side connection of course, and do it up as tight as you can by hand. Then mark the "12 oclock" position on the cap. Ensure thay you fit the valve so that it moves vertically along the imaginary 12 oclock to 6 oclock line.Fit the end of the valve stem with a standard brass adapter to take plug-on hose fittings (Hozelock or the brass equivalent - better).You may have to introduce the float end of the valve into the aquaroll at an angle but once in, screw the cap up, making sure your 12 oclock mark comes back where it should.All this is far easier to do than to describe - I'm beginning to have some sympathy with those who write instruction leaflets.
If your OH is good at diy this would be quite a easy & cheap fix ...
But you will need a spare cap for your aquaroll for normall use
This is the
side entry valve that you will require plus a hose & conectors
This has all of the parts
shown
Grey waste pipe is available in various lengths, I have two & join them together when a longer length is needed
