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.

Delivery
After searching prices pool supply was the best, even though
The shipping is high. But with the rebate price is still good.
But cannot get a shipping date and no answers from phone calls or emails.

A great replacement
Our old DE filter grids finally tore so it was time for a replacement.
Service was amazing with getting it ordered and shipped right away (thankfully they had it at the local DC in Phoenix, AZ.
Easy to install and after running our pump overnight the water was crystal clear and ready to swim in!

Another great buy from Pool Supply Unlimited
My pool guy helped me pick the perfect filter with the best price. He just happened to find it at the same place I previously got a pool pump for much less than anywhere else. Very pleased because my pool is working perfectly now!
