How to connect pressure reducer to irrigation system?

Hello,

I'm setting up an irrigation system (using 13mm and 4mm poly pipes + Pope veriflow drippers) for my home garden and came across few blog posts re importance of a pressure reducer. I decided to by this: 

https://www.bunnings.com.au/toro-25mm-single-pressure-reducing-filter_p3120617

I bought 13mm "nut and tail" adaptor for bottom to fix the poly pipe. However, Im just wondering how I connect the top to my outdoor brass male tap (I believe it's 25mm or 20mm) or a tap timer (still male threads). I couldn't find any suitable adaptor for this connection. 

Appreciate any recommendations on this. 

Feel free to suggest any other (or better) pressure reducer and filter that's more simpler to install. The reason I chose this over other brands is just considering customer reviews about leaks and faults. 

Thanks.

Re: Tap adaptor for pressure reducer

Hi @Sanju,

 

That is an inline filter/pressure reducer, not one that you'd attach to your tap or timer. You would attach a barbed fitting to either end and insert it in your 13mm pipe. If you were after one for your tap or timer, I would return it and instead pick up a Pope 300kPa Pressure Reducer. If you're after a separate filter, you can instead use one of these Holman 13mm Pressure Reducer And Filter Assemblies.

 

If you did want to use the filter you have, you would first attach a nut and tail to your tap, then a short, say 10cm length of 13mm pipe. The filter would be attached to that. Then, off the bottom of the filter, you would attach another barbed nut and tail, and then connect your 13mm irrigation pipe to it.

 

Please let me know if you have any questions.

Re: Tap adaptor for pressure reducer

Thank you for the reply. Is there any difference in inline pressure reducers vs the ones attached to the tap? I wanted to avoid this: https://www.bunnings.com.au/holman-13mm-pressure-reducer-and-filter-assembly_p3120097 considering past customer reviews. However,  re https://www.bunnings.com.au/pope-300kpa-pressure-reducer_p3121926 should I go for 300kPa one or 100kPa?

 

Thank you.

Hi @Sanju,

Good question. For what you are using - I'd go for the 300KPA one.

Hi @Sanju,

 

As @robchin mentioned, I'd also recommend the 300KPA version.

Here is one for mister setup, saves many trips back to the tap to fine tune the flow!

 

Cheers

Thank you all for the suggestions.

 

I managed to set this up using Pope 300kpa ones and working fine so far.

Need to figure out adding an inline filter later.

Thanks @AlanM52 for the 3 way outlet idea as I need a separate outlet to connect my hose when needed.

Re: How to connect pressure reducer to irrigation system?

HI Sanju.

The filter should go after the timer. You'll need one for each line. I work at Bunnings and we sell these ones: Pope 13mm Poly Inline Barbed Filter - Bunnings Australia

Just note the direction of flow arrow when installing :smile: 

Well done.
