Despite the title this is mainly a 'plumbing' question...
I'm trying to put together a low-cost simple garden watering system that I can bury a couple of inches under the soil. Gardena and Hozelock both do watering systems, but the delicate drippers and sprayers are prone to blocking, are fiddly to set-up and have to be above ground where they would be vulnerable to attack by my rotary mower. They're also fairly expensive. I'd prefer to lash-up a home built system using 15mm and 22mm plastic pipe to feed lengths of 'soaker' hose, all of which could be safely buried out of harms way.
Has anyone already done this? Would you recommend Hep2O for shallow burial, or would I need to use the blue (MDPE?) pipe instead. Has anyone found a plumbing connector that would be suitable for joining 15 or 22mm plastic pipe to short lengths of 'soaker' hose? I haven't bought any samples for testing yet, but soaker hose *might* be the right sort of size to jam over 15mm pipe. Alternatively, maybe it will accept one of those reinforcing inserts and fit a Speefit or Hep2O connector :-) Either way, I'm reluctant to use something like jubilee clips because they'll rust away very quickly. To get round the problems of freezing in winter, I'd probably blow air through the system at the end of the season to push most of the water out.
Anyone had a go at this?
