I was given a Waterways above bench filter and it was due for a new filter. One simple phone call and the very helpful lady knew which filter I was describing and how much a new filter would cost me. She explained the other options too such as self installation. I love making decisions with all the facts first, this made it so easy. I booked in the service man, he arrived in the allotted time frame and was in and out very quickly, he was also very professional and friendly. If I'd know it would be so easy to change my water filter I would have called sooner. Definitely a good company to do business with :)
