Hi All.

Long time lurker, first time poster. After a long time investigating building a DIY 25 metre lap pool (including a container pool & other options ) but just hitting too many hurdles we decided to go for a fibreglass pool with swim jets as a slight compromise but the benefit of actually having a pool while the kids are still at home!
So we have gone for a 9 meter x 4 meter fibreglass pool. Like a lot of posts I've read on here the pool builder has his standard supplier of equipment and not that interested/knowledgeable about alternative options so this site has been an invaluable source of information on my very steep learning curve. The plan is to have a 3 ft waterblade and swim jets. There will also be a heat exchanger for solar heating.
My preference was for 2 x 4hp Badu swim jets but they are twice price of a locally sourced 2 x 3hp pump/swim jet available here in NZ. My second issue was the poolshed for the equipment I've built is on the opposite of the house to our entertainment area so I realised I would need automation to switch a valve to divert water to the water feature or else I would never turn it on.
So I've gone for
Easytouch 10 + screenlogic,
Pentair intelliflo VS pump
Freeflo SWG 35g/hr (by Pentair)
Pentair Globrite LED lights x 2
Clark Synthesis underwater speaker
Sand filter (with glass media ) 4sqft filter area
swim jets 2 x 3hp pumps
3 x Intellivalve 3way valve actuators
I've run 3 phase power 240v to the pool shed and will run each pump off a separate phase

So my plan is, by upgrading to the Intelliflo 3hp pump, I can also use it as a 3rd pump for the swim jets when required (to give me a stronger/ wider swim jet). This would involve one 3 way intellivalve on the suction to switch from the skimmer return 2" line to a seperate swim jet return 3.5", then a second 3way intellivalve to bypass the filter, heat exchanger and SWG to go direct to the swim jet upsized to 3.5". In addition a 3rd 3 way intellivalve placed after the SWG to divert water to the waterblade feature when required.
I'm hoping I can set up two features in easytouch, a "swimjet " that will operate the 2x 3 way Intellivalves to the dedicated swim jet suction and return and set the pump to full speed.
And a second one, "waterfall" that will operate the other 3 way valve to the water feature and increase the speed of the pump to around 45GPM.
The rest of the time, I'm hoping to run the pump on low speed for approx 12 hrs during the day for the SWG and for the solar heat exchanger. ( The solar heats our under floor heating for the winter.)
Sorry for the long novel but my questions are;
Does this plan seem feasible? My main question is if you wire the SWG to the pump relay in Easytouch, can Easytouch turn off the SWG when switching the 3way Intellivalve for the swim jet and bypassing the filter/SWG ?
The intellichlor is unavailable in NZ, so I have to go with an alternative and will obviously lose some functionality. My minimum pump run time will be dictated by the need to run water through the solar heat exchanger but presumably I can just adjust the "power output" if I need to reduce the amount of chlorine produced?
Is one 2" return from the skimmer enough to run the water blade at 45GPM or should I get a second return / skimmer ?
Any tips/ comments on swim jets ?
Any tips comments on underwater speakers ?
Hopefully the pool will be going in in about 2-3 weeks so will post more photos as construction begins, for now here is a photo of the pump shed (possibly slightly over engineered :) )
Thanks in advance for any advice, it's been a steep learning curve, but this site has been fantasticIMG_7106.jpg

1218,

Keep in mind that I have no clue as to what equipment you can get in NZ, or how it differs from standard US equipment... :scratch:

Somethings that look odd to me...

An EasyTouch is normally an ET4, with 4 relays, or an ET8, with 8 relays.. I have never heard of an ET10.. There is such an IntelliCenter 10, but with the IntelliCenter you do not use ScreenLogic..

An IntelliFlo is a great pump, just don't know if they make a 3 phase version..

The pump/filter relay will come on any time you are in the Pool or Spa mode and the pump is supposed to be running. This is a fixed operation.

An EasyTouch can only control 4 valves.. But.. two of them are the Intake and Return valves, that control the switching between the Pool and Spa modes. There operation can't be re-programmed. The other two valve drivers (A and B) are user programmable. That does not mean can't come with the a scheme to use the Intake and Return valve for something else, you just can't turn them on or off unless you can switch between the pool and spa mode.

Good luck with your new pool build.

Thanks,

Jim R.

Thanks Jim.

They seem to market the Easytouch 8 as an Easytouch 10 on the Australia site because it has 8 auxillaries and 2 permanent 15Amp permanent power. Yes the intelliflo will be single phase, sorry I just meant each 3hp pump will be on a separate circuit run from a separate phase to help spread the load.
So if I set up the swim jet circuit as my "Spa Pool " can Easytouch turn off the SWG when in spa mode ? Or will I need to program the return 3 way valve to divert enough water through the filter & SWG to keep it running (obviously losing some output for the swim jet , but it is the bonus third pump ) Then I can use the third valve driver to control the water feature ?

Thanks Andrew

1218,

The pump/filter relay is used to control the power going to the SWG's power supply.. The idea being that if the pump is not running the cell will not get any power.

The pump/filter relay is programmed to close any time the system is in either the Pool mode or the Spa mode AND the pump is supposed to be running.

I am not sure what it is you are trying to do??? In my mind, if the pump is running the cell should be making chlorine.

Plumbing wise, you never want to make it possible for the water to be diverted away from the salt cell if the cell can possibly get power.. Cells that have power, and no water, can and have exploded.
