“I have a number of Rain Bird Riser Connection kits (RCKIT-1PS) in my yard which were used to convert my sprinkler system to dripline. They work well, EXCEPT, after a few years the connection between the riser and the dripline fail, usually when you are out of town, leading to a big water bill.
These adapters are a very effective, reliable and cost-effective replacement for the black "Tee" on the RCKIT.”
