This was given to me and I was told it had been in storage for awhile and had a leak. After cleaning it up and filling the clean water & solution tank with just water, I discovered what appears to be a seal or something missing on the bottom of it where it mounts up to the dirty water tank. As soon as I fill it, the water pours out the bottom of the clean water tank hole. I need a manual so I can use it the right way with all the attachments to get the most out of it, and also a diagram that shows the parts and how they go together to see if there is a seal or something that is supposed to go there, maybe a part number and then maybe I can find some place that would have it. But I need to know first what is missing and the proper part name for it.
