My Reticulation has Lost Pressure

Ok so you have noticed a drop in pressure on your sprinklers.

Believe it or not the first place to check is your water meter. Make sure someone hasn’t turned the pressure down here. It happens… I have no idea why people do it but that’s the first test.

Then check and see if it is on just one station or on all.

If its ‘all’ then you have a break in your mainline – that’s the 25ml or 40ml main pipe that feeds to the solenoids. This should show up in a large puddle of water somewhere.  You may need to leave it on for a while if its just a small crack as it will take a while for it to show through.

If its just one station then you will have either a broken pipe in the line or a broken riser.


Check for pooling around the sprinklers as that will indicate a riser problem. If you can move the sprinkler then its likely the riser is broken. If not then you will need to check the line for cracks and breaks. This can be a long tedious process as you will need to locate the break and sometimes its not obvious.

A small crack can result in a significant pressure drop but can be a pain to find.

Here’s one my father worked on recently. His pressure on this one station dropped significantly and he ended up having to trace the line until he found the problem – a joint that had cracked.


If you have a drop in pressure then the only solution is to keep looking till you find it – or call us and we will look for you!
