Waterpump attachment for drills
Model: Wolfcraft 2202000
For pumping out water from fish tanks, or household plumbing jobs.
Brand new sealed in packet. Sells on Amazon for nearly £11.
I use one of these for my fish tank, and I bought this as a spare in case of failure. But the one I use has never failed, and the manufacturer gives a 10 year guarantee on this product which is a good indicator how reliable they are.
There is an excellent video on Youtube for this product where a professional plumber demonstrates this model. See link:
