Other reviews reference the fittings, and those are accurate. The only faucet I could use the included fittings on was my outside spigot (which works for me, since it's within 50 feet of tank inside) but even a large name-brand hardware store couldn't order adaptors that fit the inside sinks.HOWEVER--it's worth every cent! Other than running in-and-out to switch settings, this aparatus makes water changes a cinch! I have recently upgraded to a 75-gallon tank for my turtles and this is the cleanest my water has been in EVER! Not only that, it goes longer between changes when when I use the vacuum--normally,with a stong filter I get 7 days max--I can now go 9 easily, and 12 without turtles staging an active protest. I would definitely recommend this product for those looking for a quick-and-easy water exchange.
