How Much Do I Pay for Water in Perth?

Posted on 16th September 2013 in bore, General

The cost of Perth water increased another 10% in 2013 so it is more important than ever that you are careful with the use of your reticulation. It is estimated that up to 50% of household water usage is attributed to the sprinkler system so it pays not to waste any of that water.

One option I encourage people to consider is the installation of a bore. While the upfront cost of around $4K is significant if you plan on being in the property long term then this is an option well worth considering.

The price of water* is tiered i.e. the more you use, the more you pay.  This is to help encourage the careful use of water.

  • 0 – 150 kL costs $1.381 per kL
  • 151 – 500 kL costs $1.841 per kL
  • Over 500 kL costs $2.607 per kL

Flow Control Solenoid Valves

Posted on 11th June 2013 in Products, solenoids

So what’s the difference between an ordinary solenoid valve and one with flow control?

 

flowcontrol

 

 

Basically its the large ‘dial’ in the middle that you can turn to adjust the rate at which water flows thru the valve. You may choose to use one of these if you have a small station and do not want you retic operating at full capacity.

For example some people have a small veggie patch that needs some very specific watering. Rather than adding the veggies patch to the lawn station or to other garden beds they would irrigate it separately. In that instance it may be necessary to reduce the flow and use this type of valve.

Any alternative is to use an inline tap to reduce to flow.

Transformations

Posted on 11th June 2013 in In My Own Backyard, Sir Walter Turf, sprinklers

When someone calls us to get to work on their backyard or front yard then essentially what they are hoping for is a transformation – a complete facelift that will have you say ‘wow!’

We don’t often get to go back  and see how our jobs look a year or two later, but this is one job I will stay in touch with because I drive past it every day.

Just 300m from our home is this residence right on the beach in Yanchep. It has had both an internal and external facelift over the last year or two.

Last year we came here and did the retic and turf at the rear, and then today we went back and completed work at the front. Here are some shots from a year ago as well as some pics of how it looks today.

Rain Sensor Wet or Dry?…

Posted on 26th May 2013 in Controllers, What's Going on There?, wiring

If you have a Holman 4/6/9 controller and the display looks ok, but it doesn’t seem to be working then the first thing to check out is whether the rain sensor display says ‘rain sensor wet’ or ‘rain sensor dry’.

If it displays a ‘wet’ message then it means that there is no 24v power going to the controller and therefore no power to operate solenoids.

There are a few things that could cause this:

1) check your RCDs in your meter box as if one of these has tripped then you won’t have power to the box.

2) check your fuse. Most likely a fault will have blown the fuse.

3) It may be that the transformer that converts 240V to 24V has died. Not much you can do here but replace the unit.

But before you call someone out do the ‘wet/dry’ check first!

The Hottest Summer on Record

Posted on 11th March 2013 in General

Its been a busy summer and a hot one too – in fact the hottest one Perth has ever known which would explain why by this time of year we are a little weary!

If you are considering installing some turf then now is a fantastic time to do it, but I’d move quick before winter hits and we enter the season where lawn goes dormant.

We are still busy but have definitely noticed the slow down with the cooling weather.

Look forward to hearing from you

Why Are My Sprinklers Just Dribbling?

Posted on 18th January 2013 in solenoids, What's Going on There?

wiring a solenoid perth reticulation

I went to look at a job this week where the sprinklers were working, but barely so.

Each station would dribble a small amount of water, but there was nowhere near enough to run the system. What was going on?…

I guess the logical cause had to be the master solenoid being stuck and thereby reducing pressure all round. However I have changed these over before only to see no change in the performance so I was cautious, even moreso because the master was buried 600ml deep, encased in bricks and covered in rocks and rubble. Not fun to get to!

The first check is always to make sure the water meter is fully on and operating properly – which it was. Then to begin digging…

When I finally uncovered the MV I discovered it was a jar top Richdel, and that was encouraging because often you can just screw the stop off, replace the guts and be done.

So I unscrewed the top section and removed it. The diaphragm was stuck to the lower section of the solenoid body and as I peeled it away the centre spindle came with it.

That hasn’t happened before and I didn’t like where this was going…

My hunch was that the diaphragm was no longer opening sufficiently to let water thru and with the spindle now removed it was never going to work properly.

I screwed it all back together with a new diaphragm to see what would happen. Nothing changed.

So I cut the main pipe just after the MV to see what kind of water flow was coming thru. It was lousy, obviously restricted, so the only option was to dig it all up and replace it. A little while later a new master valve proved to be the answer and one very happy homeowner had his sprinklers operating again.

Most retic is a logical process of elimination, as well as the occasional bit of trial and error!

My Retic Won’t Stop – What Causes That?

Posted on 12th January 2013 in Controllers

If you have set your retic to come on automatically but find that it doesn’t switch off then chances are you have set it incorrectly.

The most common cause of this issue is setting an identical start time for each station.

When you set your retic you generally only need one start time to get it rolling. Let’s assume that is 6.00am. Set start no 1 to 6.00 am and do not set any more start times!

What I have seen people do is set several start times (all 6.00am) and this seems to confuse the old retic box… If you have 3 stations or 10 stations you only need one start time, so if you are having this problem first check and see if you have set a number of start times all for the same time.
