I just purchased a USED 'First Need' water filter pump at a garage sale. The hoses aren't damaged but are aged and I suppose it to be over ten years old, and have no idea how many times the filter was used or if it was ever replaced although it is in quite good shape.
I was wondering if there is any way to check the filter, or if there is an expiration?
It came with what I believe was blue dye drops, [or perhaps it is liquid iodine?] and is it acceptable to fill a pot with water and dye and then attempt to filter it, and if the filter is still good the dye will be removed from the water?
It also has a primer filter, and my query also is germane to its quality.
I know in such a case it is better safe than sorry to simply get a new filter- and hoses- but the advice I seek concerns the expiration and checking of a used filter when you don't know its age or use, and if there exists a way to verify its integrity while not in the field.
thanks
