Reticulation in Jindowie with Poor Water Pressure

 

This morning I laid the main retic line for a client in Jindowie (a part of Yanchep). I’ve written before about water pressure issues in this part of the world and today we hit the same problem again.

I use Richdel solenoids 99% of the time, but today they wouldn’t seal. They need a certain amount of backpressure and the water being what it is up here I just couldn’t get them to work.

I changed them for Hunter PGVs and they worked fine. I’m not sure why Hunters will operate with the lower pressure, but they seem to be the answer when the Richdels fail.

Lucky I had 4 onboard to subsititute!

Laying Kikuyu Turf

Posted on 31st May 2012 in Installations, Turf

Its been over 5 years of running this business and only yesterday I laid kikuyu turf for the first time. Kikuyu is a cooch variety and is typically used in parks or for commercial applications.

It is hard wearing and sturdy. It has a broader leaf than wintergreen and yesterday’s batch felt quite spongy, although I don’t know if that is typical.

We can supply and lay kikuyu at the same price as Wintergreen if it is your preference.

 

 

Village Green Turf

Posted on 25th May 2012 in Installing

 

I had a request yesterday for ‘Village Green Turf’, a variety I have heard of but never used before. I did some research and discovered that it is a form of kikuyu but one that has some improved features. See the chart below for its strengths and then refer to the brochure here for more info. We can supply and lay Village Green Turf for you – just call now for a free measure and quote.

 

How to Install Sprinklers by The Kerb

Posted on 13th May 2012 in Installations, Installing, Products, sprinklers

 

The first time I did some DIY retic I tried to install my kerbside sprinklers by digging along the line of the kerb.

Big mistake!

After 10 minutes I had all but given up. You see the soil along the kerb is actually roadbase. It is hard and rocky and not easy digging. If you want to install sprinklers along the kerb then dig a trench one metre away from the kerb and parallel to it and then ‘t’ off to the point where you need sprinklers. You will still need to do some hard digging but it will save you a lot of effort and you will do the job right.

The other tip with kerbside sprinklers is to make sure they are well below kerb height – because they will get driven over. If you’re lucky they won’t get damaged, but if they are even sticking up a little bit then expect to replace them regularly.

I get calls from one client a few times each summer to replace the same sprinkler. Personally I reckon it would be easier just to sink the sprinkler a bit lower…

Can I install Turf Without Retic?

Posted on 8th May 2012 in General, Installations, Sir Walter Turf

The short answer is ‘yes of course’.

The longer answer is ‘why would you?…’

Obviously budget is a consideration, but if you are going to spend a lot of money on earthworks and turf then it only makes sense that in a climate like ours you make watering your turf as easy as possible.

If you lay turf in Perth then you can ring 131039 to get a watering exemption and that will allow you water 3 times a day for around 30 days. In summer this is essential. Obviously its less of a consideration in the cooler months, but I often tell people that the only thing that will kill a new lawn is insufficient water. (Not strictly true – but let’s assume it is pest free)

I have laid a couple of lawns without retic only to be called back in a month or so and asked to install sprinklers. If the lawn hasn’t taken it is actually a much harder (and more expensive) job because it involves lifting the new rolls of turf, digging where they were and then trying to get the ground level again. Its much easier just to pull a trencher thru a fully established lawn, so if you have to go this route then wait around 3 months to be safe.

So if you are considering laying a new lawn then please please please… make sure you have reticulation!

There is no ‘warranty’ with new lawn as it is a living organism and will only respond to whatever nourishment it receives from the owner. We do guarantee to lay it correctly and provide it in excellent weed free condition, but after that it’s up to you to make sure it is kept healthy.

So if you’re considering just wacking down some lawn to make things look better then think again unless you have functional sprinklers…

 

 

How Does My Miniscape Reticulation Work?

Posted on 7th May 2012 in Drip Irrigation, Installations

 

If you are using miniscape / netafim sub-surface irrigation then you need to know the following:

a) The pipe (brown stuff) should be laid at correct spacing – for example some miniscape is rated at 30cm intervals and it needs to be laid accordingly.

b) It needs to run for around an hour to apply the correct amount of water.

c) The picture above is of the line flushing valve. When you turn the system on this will release water for around 30 seconds. It can look like your retic is ‘leaking’ but its not. Its normal.

d) You shouldn’t have more than an 8m run of brown pipe before it plugs back into the poly. You will lose too much pressure otherwise.

e) You should have a vacuum valve at the higest point of the system

f) You can also add filters to ensure the water is free from contaminants
