If you are comfortable in programming go and edit your configuration. Delete the cell and add it back.

The SuperPump VS has a maximum head of 65' so that is the maximum lift of the water, albeit at 0 GPM. In reality, 15' is nothing for a pump like this so no worries about priming even at RPM less than full speed.

You still stuck?

@ChrisABS ever see this?

- Replace spa pump with 1.5hp Pentair Intelliflo VSP
- Replace pool pump with 3hp Pentair Intelliflo VSP

I want a 3 HP pump for the spa jets to have strong jet pressure.

I would go with two 3HP Intelliflo3 pumps.

Boston_Pool said:

- Install a AquaCal SQ225 to the left of the propane heater (or another heat pump -- open to other brands). I would like a bypass to select which heater I want to use (propane or heat pump) or bypass the heaters all together -- confirmed I have enough power. NOTE: heater on the right is for the spa

Aquacal is good. So is Built Right or Gulfstream.

Boston_Pool said:

- Install CircuPool RJ-60 PLUS after the heaters (right now there is no space and the return pipe goes back under the shed)

Jandy also recommends the HP before a gas heater.

Pentair recommends water flowing first through the Heat Pump and then the gas heater...

Welcome to TFP.

Maybe some pictures and a sketch of what you have in mind can get some ideas flowing.

Welcome to TFP.

Maybe someone with a similar AGP will advise you.

@Mdragger88

How you doing with the bearings?

You're doing it again.

Get the 1766. Maybe the others start behaving and you can prove them occasionally going forward.

Sorry, no one appears to have advice for your situation.

I am not sure what you are looking for exists. If you find it, let us know.

What is holding the forms at the corner you have worked on? That looks like rebar but it might be sticks but still can hurt if someone falls on it. Yes I am a worry wort LOL

Oh those! Ground stakes. It never even occurred to me since they sit so low to the ground but you're right, it could be dangerous.

Does this say it still has 80% of its life?

Click to expand...

Flip it right side up and you'll see its *used* about 80% of its life. its kinda useless though as we don't even know where the cutoff is. Obviously you could be 80 to 99%, but the light could also come on at 6001 hours of 10k, or 7001 of 10k. So you have between 39.99% and 1% left.

Also, its mounted wrong and its dangerous to have such a flimsy flow switch fighting gravity. It needs to be 'upflow' or horizontal.

@Newdude and @ajw22
Thanks for your help! Turns out the clone T-15 cell fit and worked perfectly! So thank you
Weirdly when I got the new cell in - the salt reading was still 2500. I had another digital tester that was reading 3200 and 2 test kits read over 3000 on the salt content -- all 3 tests must have been WRONG because the minute I assumed the 2500 could be right and the minute I added salt the reading went up to 3400 (with 3 bags). So @Newdude you were apparently right. I wonder if the cell was really bad?

I'm ordering the 2 inch one . Glad I checked ! What kind of sand ?

Click to expand...

High-Rate Sand: No. 20 Silica Sand (0.45 mm–0.55 mm)


Pentair uses US Silica Mystic White II sand for all of their testing. It may not be readily available at Ace/Home Depot though. In general, we recommend getting your pool sand from a pool supply store and not a hardware store as they are far more likely to stand behind what they sell than a big box store.

Be aware that members have had issues with Quiikrete Pool Sand. Members find that Quikrete Pool Sand is too fine and perceptibly heterogenous (i.e., not filtered to #20 specifically). It does not filter well and tends to blow back into the pool. A search in the Forum can provide more information about the issues.

Swimming Pool Sand filters generally use #20 silica sand which is approximately .40 to .55 mm.

If the slits in the laterals are a little bit large and the sand is a little bit small, then you can get some sand passing through the laterals.

MYSTIC WHITE II filter sand has three effective sizes, 0.49 mm, 0.65 mm or 0.80 mm.

MYSTIC WHITE® II 0.49

MYSTIC WHITE® II 0.65

MYSTIC WHITE® II 0.80

Also I'm noticing I have more jets from pump into pool that I do not see any water movement thru them. Please tell me that's not hard to fix . There are several that don't appear to work .

Depends on the way your pool returns are piped.

First thing is to look into each jet and see if it is clogged.

What is the make/model of the pump?

FWIW, the return trip of the water in a fully primed system from higher to lower elevation gains pressure, not velocity

Click to expand...

thanks, its a hayward super pump variable speed...might be up to 1.65hp but definitely less than 2. pool lines are all 1.5in

You live in Phoenix. Daytime summer temperatures of 110 degF plus. I would not advise putting a solid safety cover over the pool and just leaving it without maintenance. Water temperatures will be in the low 100's. Your scaling tendency (CSI) will skyrocket.

Best to drain it and keep it dry and refurb it later. Might consider a drain and then cover.

Classic sign of algae in the water clogging your filter.

You can do an Overnight Chlorine Loss Test or skip right to the SLAM Process
