Negative Positive
Title: not worth the cheap plastic its made of...
Review: 1) it leaks at the valve knob (followed the included instructions to fix this, all they have you do is flush it to remove any filter media. mine leaked straight out of the package)2) it doesn't even close off the water flow completely. if you are familiar with the concept of a siphon, then you know that you need a full closure here3) when priming the pump, air accumulates in the valve body, causing a poor primei would have given the product 0/5 stars if i could. you will be farther ahead by going to your local hardware store and purchasing 2 quarter turn valves and a few hose clamps
