I don't know Waterway, I know Hayward. But I haven't heard anything bad. Besides, if, after 5 or 10 years it dies, you can replace just the pump. The filter should be completely rebuildable. (actually, the pump is too, but in 10 years the new pumps will be far more efficient). Besides, A/G pool plumbing is a snap--all the pipes are where you can get at them without digging or busting concrete! Once you do something the first time, it's nothing but easy.

Personally I've found Island Pools (the company that owns Leisure Living and PoolSupplies.com) to be very reliable and cooperative. Other folks have had some difficulties but I never have. I got my FantaSea (16x40--20k gal) from them, and selected a 200# Hayward filter and 1hp Superpump (2spd) without them being a "matched" pair on a tray. Going into year 5 with them with no problems. Neither was the "recommended" combo, but...I had been a fan of PoolForum and PoolSolutions for a couple of years at that point and did my due-dilligence--even called Hayward to see if they recommended or dissuaded you from pairing these.
