It does the job but it's kind bulky due to the way it probably has to be designed as a Y. My only gripe, which is not really an issue with the product itself, is that the corrugated fish pond tubing never really seals perfect on these plastic barbs and there is always a small drip around that connection. I dealt with this by keeping the whole Y connection inside of the pond area so that the tiny leak goes back into the pond. I placed it near my rock water fall so I could camouflage the connector with rocks. Valve seems well built.
