Skimmer and Drain, Vacuum port, Pool vacuum

Jimrahbe
Jeff,

Your pump only has two inputs... Vac Line and your Skimmer (and maybe your Main drain..)

Based upon your plumbing, your main drain is plumbed into the bottom of your skimmer.

This mean that unless you have a floating diverter valve under your skimmer basket, then you effectively have no main drain suction. And even if you do have a floating diverter valve, it most likely is not working, as most do not, or they are very intermittent. Show us a pic of your skimmer, looking down, with the basket removed..

The good news is that you do not need a main drain at all... :mrgreen:

The only way to have your Vac and your skimmer both work well, at the same time, is to increase your pump speed..

Your circulation issue has a lot to do with having no eyeballs on your returns.. Water will take the path of least resistance every time.. It is much easier to go out the closest hole, then to go all the way to the farthest hole..

The fix is to install eyeballs.. Make the first eyeball the smallest, the middle eyeball a little bigger, and the last eyeball the biggest.. This will even out the flow at all three returns.

Thanks,

Jim R.

VS / VFD Pump & Flickering LED lights

Jimrahbe said:
AC,

I removed the last sentence in your post, as that is not how our site works... Everything else you said is perfectly fine.

That said, until recently I had three pools that all had Pentair VS pumps.. The three different houses all had plenty of LED lights, cheap and other wise.. None of the houses had any flickering at all..

This complaint is not one that I have seen here before, so it must not be very common.. :scratch:

Not sure if you just got a bad pump, or your electrical gird is different in some way, or???

In any case, let's see if any of our members have seen this same issue.

Thanks,

Jim R.

Thanks Jim. Sorry about that, and edit accepted and justified.

So this issue relates to VFD, and the level of harmonic distortion that VFDs produce that feeds back to supply side. Depends on the quality of the VFD circuits I am told. But I have also reached out to Pentair in case it is faulty VFD filter on my particular unit and not related to this unit in particular (I own it, so not going to denigrate it too much).

Be keen to hear from anyone else who might have similar experience.

Pool tech doesn’t agree with SLAM

I can’t get it to stay at a decent number. I did an overnight test a few days ago and it went down 3 ppm overnight. I have had suspicions that I had algae but wasn’t 100% sure.

Your chlorine will keep on being consumed until you kill the algae and have an algae free pool.

Then you will lose normal 3-4 ppm per day from the sun UV consumption.

Skimmer and Drain, Vacuum port, Pool vacuum

Jeffrito
Hi, My Pentair Rebel gets stuck on the 2 drains, and stays in the deep end. I'd like to retire it after 3 years. To make it move (slowly) at 2400 RPM I have to move the lever all the over to the left which cuts off the skimmer. Having the lever set so both function has never worked. So I run the vacuum 6 hours and then walk out and move the lever all the way over to the right for 2 hours (Pump runs 8 hours). I'm sure this is not the way to do it as it infers there will always be an old retired guy around to mess with the pool settings.
I have considered getting a robot that I can drop in and it cleans the entire pool and then is taken out. This would mean closing the side vacuum port.

Questions
  1. When the side vacuum port is closed due to not using a suction vacuum, does the lever for the valve between the port and the skimmer/drain stay all the way to the right? How do I test the main drains, I can't feel any suction? And will I get enough circulation using just the skimmer and the bottom drains?
  2. If I upgrade to another suction vacuum, any recommendations? And should I be able to have both my skimmer and vacuum working together? And can I leave the vacuum in the pool 24/7 like I have been, running 8 hours along with the pump?
Circulation: The 3 returns are just pvc flush with the wall blowing straight out, #1 works well, #1 less so, #3 barely anything comes out. I have always felt the vacuum was necessary then for circulation.
Hope this is clear - Thanks!

Drain and refill for plaster pool

B
Please advise on the drain and refill procedure for plaster pool. I want to make sure I'm not overlooking any steps or nuance.

1. Set salt cell to 0%, turn off pumps, turn off autofill.

2. Use submerisible pumps (x2) in deep end to drain pool. Plan is to start the process around 5:30pm. Our backyard is in shade at this point.

3. Rinse filter cartridge.

4. Ledge is 19' x 6'. Would it be a good idea to keep ledge plaster moist during the process with a light sprinkler? Temps range from high's 90's to low's in the 70's.

5. Once drained, begin refilling in deep end. Water hose + autofill.

6. Once filled, should I add water to the filter to help with priming? I remember the start up techs doing something similar. The equipment pad is about 15' away and 4' above pool grade level.

7. Turn on primary pump.

8. Adding chemicals:
Add Calcium? Fill water is ~100ppm. CH was approximately 450ppm four months post fill. Calcium has never been added previously.

Adjust pH and ALK (MA).

Add Chlorine.

Add CYA and borates (after ALK is adjusted?).

Add salt. Turn on salt cell 24 hrs after.

I appreciate the help.

Required vertical clearance on Pentair CCP520

TropicalWaters
We did as PoolStored suggested and took the air relief and gauge off. Then we were able to remove the cover fairly easily by tilting it to the side as it came off. Pool filter is nice and clean now and I've gotten over my fear of shutting all the valves and depressurizing the pool system. Since it is below grade I had nightmares of something breaking and the entire pool draining out into the pool equipment room before we could fix it. Thanks for the help!

Looks like I need a new SWG

C,

Your Power Center needs to be connected to your EasyTouch two ways..

1. The AC power to the Power Center MUST come from the load side of the Pump/Filter relay. This prevents the cell from blowing up if the flow switch fails.

2. The Surge card inside the Power Center has a 4 pin RS-485 com port.. This com port should be connected to the RS-485 com port in your EasyTouch (J20).. You will need your own 4-wire cable to do this... I'd use 18 AWG wire.. Connecting the RS-485 will allow the cell to report the salt level to the EasyTouch, and allow you to control the cell's output % remotely.

Thanks,

Jim R.

Also, I connected it to the load side on the same terminals the previous Breeze SWG was connected. All seems to be running good.

This forum is great, btw...

Coleman Steel pump GFI plug question

I
It is not in the manual and I can’t find an answer online.
My Coleman Steel 22’ above ground has a pump with a yellow button, red button, and a black button. It has 5 red lights to where the black button can be pressed to select 2, 4, 6, 8, or 10hrs.
Self explanatory? NO!
If I select 4 hours it runs for 4 hours and stops. Nothing more.
I did SOMETHING to where I selected 8 and it ran. Next day I went out and it was running again.
Is it designed to run the selected hour and stop until you turn it back on or is there a way to select an hour setting and it continually starts and stops at a prescribed interval?
