waterways crystal water filter
I bought this filter to replace a waterways filter which had failed after several years of service. I have continued to buy this brand for several reasons. (1) parts are easy to obtain (2) the 2 and one half inch fittings give much better flow than the standard two inch fittings and (3) the price compares favorably with other filters on the market. I was impressed with the speed of shipping The filter arrived in just three days and it took me all of fifteen minutes to install it as the new fittings married perfectly with the old fittings. One question that I have which I haven't checked on is whether or not my .old cartridges will fit on this new model I have had this filter running for several weeks and it keeping the water clear.
