hi my parents bungalow was built around 1950 and has a crawl space all under the full house which is normally dry to damp which is about 600mm below ground level,over the last month or so its started to get water in about half of the floor space and i looked under today and all the floor space has betweeen 20mm to 40mm of water all over i think its coming up through the floor as its built right at the bottom of a hill and ive checked all the pipes, but what im after is some kind of pump that will get rid of it, i bought 3 so far that wont do it because the water is not deep enough is there any thing outthere that will do the job tryed the wet vac but gave up after 5 hours and it hardly dropped ..thanks
