Yeah I can't help you on that. I will have that same possibility of the same failures. The drip thing I got came "highly" (LOL ) recommended. The pressure regulator is built in. 8 emitters each dripping .75 gal/hr, cap off the ones you aren't going to need. Pretty good for $16. I'm thinking I'll hook it up with a valve to adjust pressure just so it gets what it needs to put out .75/emitter. I'm probably only going to need 2 or 3 anyway so if it fails it doesn't go ballistic, still won't be ideal but hopefully not catastrophic either.
