OK, so having stared at my swimming pool/hole for a few days, I tried to work in it this weekend... after an hour of struggling in the porridge I gave up. I now have some inkling of how the soldiers in the trenches felt about the mud! So i need to empty the water from the hole so it can at least have an attempt at drying out. I need a pump that can handle dirty water, can pump close to the base (a lot can pump down to 4", well its not much deeper than that in places) and can shift around 2500litres in a reasonable time... suggestions? or can anyone lend me one for a couple of weeks?
