On Friday I had a call from a client in Yanchep who had installed a solenoid, but was having problems. The two stations in the back were coming on together.
So I went out to see what was going on.
What was odd was that the two rear stations came on together but they didn’t come on when the front retic station was running. Normally if a solenoid fails open it stays on with every other station.
But in this case station one came on, then station two and three together.
So I checked:
- The direction of flow on the solenoid he had installed. It was correct.
- The wiring and the voltage at the solenoid. It was all perfect.
- Whether the solenoid was clogged with glue or dirt, but both were fine.
- Whether the controller had failed and was sending voltage on both stations rather than individually. It wasn’t…
There was no apparent reason and I was running out of options as all of the logical solutions were coming up blank.
Finally I decided to check whether a different controller would get a different result so we wired one up to test it. As I was doing this I asked the client why he replaced the solenoid.
He told me ‘I didn’t replace it – I added it to split the rear yard in two.’ And as he said that, it dawned on me what had happened. What was once a complete station had been divided in two – but not completely. Somewhere there was still a connection underground. It was the only explanation left for why both stations came on simultaneously.
When we discussed it he agreed and I left him to dig some holes and find that elusive connection.
There is always a logical solution to retic problems, but sometimes you need to gather all the information to make sense of it.
This week I did a front yard makeover in Joondalup. It involved removing the old lawn/weed, installing some new retic and then laying some turf.
The existing turf had turned to weeds and looked almost impossible to revive, so the process was:
a) Spray existing turf / weeds and kill off what is there.
b) The bobcat came and removed existing stuff to a depth of around 100ml and then filled with special lawn mix so that it was 20-30ml below kerb level.
c) Reinstall retic and ensure all is getting covered. This involved placing sprinklers around the perimeter of the property spraying in as well as in the middle spraying out. The previous system had a row of sprinklers down the middle and consequently missed much of the lawn. I also installed a new Hunter X Core to make watering so much easier.
c) Screed and lay the new wintergreen lawn.
The budget for a project like this is usually around $3000.00.
Here’s a before and after shot so you can see the difference
When it comes to retic in Two Rocks, especially on an established property, you need to be ready for some serious digging and some hard yakka. As the suburb name suggests there is a lot of rock up there and sometimes you just have to go around what you can’t go through.
I did this job last week, installing a whole retic system – 200m of PVC – to an established property. There were lots of roots and rocks to contend with but also some nice long sandy patches. Thankfully the faithful trencher didn’t let me down and I managed to get it all done in the day.
Without the trencher there would be 2-3 days of work in this one. I used a combination of MP rotators and precision nozzles to get it all done on 3 stations.
In case you weren’t aware all reticulation needs to be switched off as of June 1st and until Aug 31st.
For most controllers it is a simple matter of turning the dial to ‘off’ and ensuring the sprinklers don’t run. If you continue to run your retic over winter then you will get fined around $150.00
If you aren’t sure how to switch the system off then give us a call and we’ll try and talk you thru it over the phone.
My son discovered this video on Youtube today and is pretty keen to make one… Luckily we have all the parts we need in the back of the Cruiser!
This is the most common controller we use so for those who would like some easy to follow instructions here they are courtesy of Hunter
Part 2 – some more advanced programming:
Sure – this is Hunter propaganda, but in my experience MPs have proven themselves to be top quality nozzles over time. It is not uncommon for me to return to a house I installed MP rotators in after 3-4 years and see them performing as well as the day we installed them.
For people with Hunter X Core Controllers this is one of the most common issues and it arises because the controller is incorrectly programmed.
What happens is the system comes on at 5.00am (or whenever you have set it for) runs thru the whole cycle and then does it again… and again… and again…
The problem is more than one identical start time being set.
By that I mean that start time 1 is 5.00am, start time 2 is 5.00am and then start time 3 is 5.00am. For some reason this confuses the machine and causes it behave in this way.
The reality is you only need one start time to run a program, so if you have this issue then ensure you only have one time set.
Its that time of year when you switch reticulation back on so its likely you’ll be looking for someone to service your sprinklers and get it all up to speed for what looks like being a long hot summer.
So give us a call on 0400044236 and we will book a time to get everything working as it should be, set your controller and ensure you are ready for summer.
