I have just set up a 15mil system for 2 small raised beds. 1st about 32 sq and the other about 20 sq. There is a 25PSI limiter and it's 12" OC drips. How long might I expect to water in general.? I gather, from the specs, about 50GPH.

Does anyone find the connections, as they are, are prone to popping now and then?

Does anyone know where I can find single barbed 5/8" Drip Tape Connectors without paying $25 shipping?

I'd like to get a couple more.
