I just got a used coleman spectum 255. I got it working but the floor drains dont seem to work which I imagine is why the motors are so loud. There also seems to be a leak when I turn it on. When its off no leak. Low power or filter cycle, little leak. Jets, big leak. Only I cant see where its coming from. Could the leak have something to do with the floor drains? Lastly, I found the filter for it but it doesnt stay down in the hole when the pumps are off. Is there supposed to be something on top of it? If so where do I get said part?
