New pool owner trying to understand test strip reading

The plans are wall height so the PB is probably right and when we subtract 6 inches for water height (about 2500 gallons) its a hair over 20K.

Pas, how is it behaving when you add stuff ? Have you seen said discrepancy with everything or only bleach ? I trust salt / cya / ch / baking soda (etc) alot more because they don't go in weaker than claimed like bleach might.
I’m spot on 3600 on salt. And I was going off the 22800 number.

As for the one time that tried muriatic acid the amount was supposed to lower pH .4 but only lowered it .2. But it’s back up to 8 last time I checked (but that test is an eye test so not really sure of exact number.

So you are saying put pool math back to 22800?

Arctic Spa wood cabinet repairs

No. Nobody has experience at this who doesn't damage good parts. 😉
If you're going to do it, then do it all. You'll likely need frame repair as well as cabinet. That means standing it up and rebuilding the bottom. It's a project, and you may have to remove the pumps, but requires only minimal carpentry skills.
I'll give you some pointers if you decide to get into it.

Good catch. Updated. Still without the shelf..

Wow thanks guys!
I did not know its illegal.
Afaik, that's a bit overstated. It's a violation of federal regs to replace any existing pump of 1 hp or more with one that doesn't meet efficiency standards effective July 2021. These requirements are pretty much impossible for a single speed pump to meet, so you can't buy them any more.

Existing pumps are always okay. In other words, you don't need to worry about the pool police fining you for running your current pump. :cool:

You'll love your new VSP. Fwiw, I come down on the side of getting one that integrates fully with your controls. The relay setups can be fine, but in the end they're generally more fiddly to set up and run.

As I said, use 25K.

I get 23K not including the shelf. Start with the 25K I suggested and use chemicals to adjust volume from there.

Oh okay. So the PB wasn’t too far off. He probably didn’t take into account the shelf when providing me with the gallons for the pool. I thought maybe with the actually diagram we could figure out the exact amount. Thanks again

Spa Leak

I've been troubleshooting a spa leak. Have it narrowed down to the main drains/suction line for the source of the leak. While troubleshooting, I pulled the drain covers off and noticed these 2 holes with no plugs. Should these bottom threaded holes be plugged? I am noticing that when my spa is fully drained, a few inches of water will find its way back in through these main drains. I'm assuming this is ground water and not sure if it's coming in through these bottom holes or if it's coming in through a line leak to the main drains. Any ideas or knowledge with these open threaded holes down there? I've attached a picture without the covers on. Thank you

It just means it's illegal for a pool service or contractor to install it. You can still replace it yourself though. We do recommend a VS due to the electricity it will save over a single speed. As far as AC goes, it's not all legal now either. If a unit runs on R22 and it loses freon, that can't be replaced. If the compressor goes bad you can still run it with a new one only if the old R22 is recoverable and is reused in the new unit.

Many are very happy with the Calimar especially compared to the price of the Pentair and Hayward pumps.

What Does the Flow/Temperature Switch do on the IntelliChlor?[edit]​

The flow switch also contains a thermistor that senses water temperature. The water temperature is used for the salinity calculation. If the thermistor is failing the salinity will be incorrect.

Flow switch has 4 wires on cells manufactured before September 2018:

  • Red/black - flow switch
  • Green/white - temperature sensor
Flow switch has 3 wires on cells manufactured after September 2018:

  • Red - flow switch
  • White - temperature sensor
  • Black - common
The IntelliChlor uses the Harwil Q-12DST-C2 flow switch.[2] It has an integrated 10k thermistor.[3]

With no temperature input, the cell defaults to a temperature of 77 Fahrenheit. The sensors are prone to failure. When the sensor fails and it's obvious to the software that the sensor has failed, it defaults to a standard temperature of 77 f.

To electrically confirm the cell is generating you can use a clamp ammeter to measure the DC current at the red or black wire on the surge board. It should be about 6 to 8 amps DC.

Check the amperage.

Check the cell temperature.

What is the cell temperature?

Check the amperage (DC).

Check the water temperature as shown in the video.

Disconnect the temperature sensor.

When you say to disconnect the water temp sensor, are you talking about the one plumbed in after the pump/before the filter with a lead that goes to the Easy Touch panel?
Watch the video to see how to check cell temperature and how to disconnect the temperature sensor in the flow switch.

Cut the white wire.

New Plaster & Vacuuming

I know that we aren't supposed to use our robotic vacuum or any vacuum with wheels for the first 4 weeks our pool is open. However, even after brushing twice a day for a week, there's still a decent amount of sediment at the bottom. Is it possible to use one of those cheaper style vacuum heads with just brushes instead of the normal wheeled nozzle you have on an in-ground pool vac head? To me, the brushes seem no different than those on our pool brush. I don't want to ruin our plaster but I'm also pretty picky about dirt in the pool. Thanks in advance pool pros!

Filter size ??

John,

I have a Pentair CCP-520 and I installed two Waterway filters in a couple of rent house...

Both filters are about the same quality.. I'd go with the larger filter for the same price..

I like the location of the drain plug on the Waterway much better.

I like the belt assembly on the Waterway better..

Either will work just fine.

Here is a good place to check pricing...




Thanks,

Jim R.
