Small Pool Build - Brisbane, Australia [emoji1037]

It appears that my ph probe magically recalibrated itself today while I was at work. Thanks pb! Checked by hand to confirm. Dosed via the chlorinator to get ph down from 7.9 to 7.7. Autodosing still doing not much of anything. However I have no idea what time the pb came so it may be that it will take a couple of run cycles. Still not confident it will auto dose sufficiently but very glad to have the calibration issue fixed. Will check by hand as well as the chlorinator read out more frequently in future as it can obviously can go out of whack at any given time.

My youngest had a swim tonight ??It was about 15*C outside. Took a couple of pics after he got out. Loving our TFP water. If only our equipment was TF [emoji23] It was quite windy and the returns were flowing when I took these pics so not as still as usual. Chemistry looking good. FC 8.5 Ph 7.7 CSI -0.04

LIZ!!! Look at that water!!! Are you SURE there is water in there??? WOW! You have done a great job with that! Now go jump in the pool for YOUR first dip!!! burrrrrrr

Kim:kim:

Thanks Kim! The camera doesn’t really do it justice. I might swim tomorrow for the first time. Maybe [emoji6] Next week is set to be cold so tomorrow might be my last chance in a while. Just put together a new outdoor set. It’s really for the dogs not us. Will be easier on my injured dogs hip than what they have. Wonder how long it will take them to chew the cushions? [emoji23]

Still waiting on render. Pb is upset with the renderer as he hasn’t locked in a date yet and render needs to be done before silicone can be done (i think this is to do with the drain). Then the slide will go in last. Pb wants it wrapped up by the school holidays which is in two weeks. Once they’re finished I can book in a date with the concrete resurfacing company to do the path and patio. That will be about it though the paint on the side of the house has taken a beating so we may have that painted to finish things off.
 
Stuff that....:mrgreen:

Forecast for tomorrow & Sunday down here in Adelaide is for a 14C maximum...!

BTW your water looks sublime...!

That’s what I said [emoji23] My 11 year old wasn’t silly enough to get in either.

Maximum of 14* for you tomorrow [emoji15] I think we may get one day or so each year that’s a maximum of only 16*. Today was 22* and tomorrow the same. Feels hotter when it’s nice and sunny which it is. I have also realised another reason why you should get the glass pool fencing - it stops most of the wind unlike an aluminium fence.

Water is pretty much there despite the dramas. Still tweaking run times etc. Any news on your paving yet?
 
No unfortunately - Still the weather has pretty much not co-operated if we wanted any work carried out anyway.

Been raining a fair amount and more scheduled for tomorrow. Pool is almost full again...!

I guess that is a good thing. It’s not great swimming weather and they wouldn’t be able to lay them anyway. As good as time as any for work to wait for a little while. It will be worth it.

Lets hope so.... :D

Every time I need to go out to the pool I have to put on some rubber boots simply due to the amount of mud which my backyard is currently made up of due to the previous construction activities.

I hear you on the mud and our paving is down. It’s the rest of the backyard that is mud. The turf I put down is helping but will see if it takes and dogs leave it alone. I was desperate and sick of the dirt and mud I was tracking all over the pavers.
 
Ph probe drama continues. Tonight when I tested it was lower than the chlorinator reading (so out the other way). Tested at 7.4 reading was 7.7. I did recalibrate but the easy way by setting it to my test result. Costas - I tried to undo the ph probe but water started gushing everywhere! Am I meant to turn off a valve or something? I did turn the pump off. Quickly screwed it back in lol. My first thought was that maybe the pb overshot the other way with his calibration but then remembered when I tested Friday night my result matched the chlorinator and was accurate. Hmm. Maybe the probe needs cleaning? Replacing? Will talk to pb tomorrow if I can get hold of him.

Put a skimmer sock in today as it’s been so windy. So much pollen. I will be sure to check it regularly so I don’t block flow to the pump.

Yes pump off - The water gushing out would be simply down to the residual head left in the pipe ie. any water above the probe's location which will simply empty out.

What I normally do with my configuration is to remove my pump top which relieves any residual head in my system or you can simply let the water gush out from the probe port.

So any water in the pipework above the probe right up to your filter's input will probably come gushing out if you remove the probe - Once that pipe empties then that will be it.


OK Liz - Earlier in your thread I found a pic of yours which shows the probe's location:

One thing that concerns me is the placement of the probe ie. just right after the pump.

Ideally the probe should be mounted AFTER the filter and before the SWCG cell.

Not sure if having it right at the pump's output could mean that the probe could get bombarded with heavier debri (compared to if it was after the filter) which maybe affecting its readings?

The probes are fairly fragile so very small stones or other material hitting the glass probe at high speeds etc could be damaging/affecting it.

I'd be getting the PB to move it - fairly easy job and from memory I think you have room on the horizontal run from your filter to the SWCG cell.

If you can, mount it similar like I have in my pic below - you can just make out my probe mounting assembly between the filter and SWCG cell to just to the left behind the broom handle:

Good idea on the socks - I started to use them (hairnets in my case - cheaper..!) a couple of weeks ago and they work well but as you said - you need to check them every day.

I think you are on to something! How is it you know more than my pb?! Going to call tomorrow and tell him it’s not holding it’s calibration and that the probe needs to be relocated to a more ideal position. Wish me luck! You are a genius! Please cross your fingers for me that this works... otherwise I will just take to sleeping with a bottle of acid next to the bed so I can duck out as needed!

Thanks also for your advice on removing the probe. I had thought maybe I had missed a step so stopped and calibrated per my test kit. If I test in future I will probably do what you suggest and remove pump lid (valves off I’m guessing).

I honestly don’t know how to thank you for all your advice.
 
With your equipment below pool water level you would get a fair bit of flow from the sensor port. There should be a valve before the pump and also one on your return line after the SWC. Same valves you would close to clean the pump strainer basket. With those closed, it will just be the water Costas mentioned and should gurgle out much slower.

Good suggestion from Costas about sensor location. The manual for your system shows the sensor after the filter, so PB should be happy to change it.
 
As a bonus - Once the probe is moved you shouldn't have too much water pouring out when removing the sensor due to it being positioned along a horizontal section and the senor hole will be near the top of the pipe.

I didn't realise that your pool pad is lower than the pool - As needsajet mentioned there should be a valve or two to isolate the pool from your pad otherwise water will siphon/flow from your pool to the pad equipment due to it being below the top of your pool.

My setup is the opposite - As my pad is a tad higher than the pool, my lines empty/drain back into the pool whenever I open something and let air into the system - I do have a one-way valve fitted at my inlet to my pump which prevents it losing prime.

As I stated in some other post - My PH probe has been quite solid as far as tracking my manual testing - good enough that I have been confident of its readings and only test/compare PH manually every once in a while.

Yes, I turn those valves off when I need to clean the pump basket. Well I would if I could get the pump lid of lol but have bought a strap wrench to help. Doesn’t really need cleaning at the moment. Will turn the valves off in future and take pump lid off when removing the ph probe.

I can’t believe the plumber placed the ph probe where he did and no one has picked up on it... well no one who is being paid to attend.

Horizontal position would be much better as far as removing the probe goes. Yes have those valves to isolate the pad from pool. I initially found the ph probe to be very accurate which is why I wasn’t checking the ph as often as other levels. Not sure what has happened to change that but regardless the location is not correct and needs to be moved. I’m actually thinking of asking for a new probe in case the old one is damaged somehow hence the problems I’m having now with calibration that I didn’t have earlier on. I know they’re only a couple of hundred dollars retail so they can wear that cost after all this drama. I am so done.
 
Costas, do you have a link to this recommendation? All I can find in the manual is that the chamber must be installed prior to the SWG. I have a feeling I’m going to need something solid to back up the crazy lady’s request!

Found it! I also found that the hole for the clear tubing should be a tight fit. It flaps around like nothing as the hole is way bigger than the tube. Will be asking that that is replaced too. Omg.
