Bests & Worsts Reviews from Amazon

This watering system was great once I figured out that I needed a pressure regulator. Raindrip mentions the necessity for a pressure regulator with some of their other systems but not with this one. I was having problems with the drip emitters letting out almost no water at all and the "T" connectors leaking. I thought the emitters were bad or clogged, so I tried swapping them out to no avail. Finally after about a week of very little water reaching my plants, I happened to pop one of the emitters off of its tube while the system was running. Instantly, all of the other emitters started dripping away! The pressure had been too high for the emitters to operate correctly. That's right: paradoxically, having the water pressure too *high* will result in flow out of the drippers that is too *low*. I ran over to the hardware store, got a 25 psi water pressure regulator, and put it on the outlet side of the timer. Now all of my dripper emitters work wonderfully. The timer works great. No complaints about that. So, minus one star for not mentioning anywhere that a water pressure regulator is necessary.
