Have been given a kit for the greenhouse whilst on hols. Previous
owner couldn't make it work and neither can I. It comprises a pressure
reducer joint, black tubing and a number of plastic drippers and
joints. The problem is that when connected up the flow at the ends of
the pipes is a steady drip but this tapers off the nearer to the
reducer joint you get. If you adjust the flow for a consistent drip
close to the joint the steady drip tuns into a steady stream at the
ends of the network. Have tried varying the pressure but with no
success. Can anyone offer any help?


Is there a big change in level? The main problem I had with mine using
captured rainwater was mozzie larvae clogging the jets. This was
resolved by putting a piece of old tights across the pump inlet.

Worth looking to see if some of the jets are blocked or clogged. Usually
the drip rate gets weaker the further you are from the reducer.

Thanks for replies. Fed by standard hose 70 feet from tap and controlled
on/off by old washing machine cold water solenoid in greenhouse which
then feeds in to a reducer valve and there are only 4 drips off a single
10 foot feed into 15" tubs. End of hose clamped off drips are tee-ed off
central pipe and tubs are 18" apart. Have tried reversing pipe in case
there were larger holes in drips but did not make any difference as did
making the feed pipe 20 foot longer to see if the pressure drop would help.
No supplier/maker detail as was bought from local garden centre and
packaging was binned. Sat in his shed from last year until given to me
to try, but I suspect it could be an 'el cheepo' chinese job.
