I'm thinking of fitting semi-permanent pipework in our greenhouses
(and maybe some other places) with a time switched pump to provide
irrigation. The pump will use rainwater collected from the roof in a
tank which will be topped up by mains water with a simple ball valve
controlling that. (it may need to be slightly clever so that the
mains only gets turned on when the tank is, say, only a quarter full).

An additional reason for using a pump is that our mains water pressure
is very high and tends to destroy things which then gets expensive in
lost water. A system as above will at least limit the rate of loss
considerably.

So, in the greehouses I was thinking of running plastic around the
edges and having some sort of small bore feeds to individual plants,
pots, etc. Can anyone suggest a practical way to connect small bore
feeds to plastic pipe? I know there are systems sold for doing this
but my experience with them has been that they're not very robust or
long lasting.

I would think you would be far better off using proper irrigation stuff,
rather than speedfit...

13mm pipe for your main supply round the greenhouse

Then Some of these screwed directly into this supply pipe

Then from these drip heads, some smaller pipe to each plant

Or, if you have a bed full of plants, then you run a 13mm pupe down the
middle, and then screw somthing like this directly in

When I installed a system in my back garden, i used Gardena stuff
everywhere, the only other thing I used for the pipes were 25mm MDPE pipe
under the grass as my main supply, I installed a 12v valve at each lawn
sprinkler, or lower bed, so i can control each area of the lawn and each
bed. It's all fed from 8000L of rainwater storage :-)

Easy irrigation were just the first Google result for the items I wanted to
show you, so hunt around for the best deal, I bought all my bits from a
company called Grovelands, but I cant seem to see them anymore.
