PB says I should run at 2600 RPM's

Jump to latest Follow Reply
Brent,

Have you ever tried to run the SWCG with the Multiport in Recirculate position???

If you get good flow in Recirculate it has to be related to the filter.. If the flow is still bad, you will know the filter is not the issue.

Thanks,

Jim R.
 
Definitely better. Cleaning the filter will help. However, I think that the pressure is still too high.

After cleaning the filter, recheck the filter pressure, pump pressure and gpm for each rpm.
 
Brent,

I would suggest that you open the filter and clean it, rather than just backwashing it.. Now is the time to inspect the inside...

While you have the system down, you can also inspect the salt cell.

Here are my results after full cleaning in rpm/pump psi/filter psi/gpm:

1300/5/4/8
2150/14/10/41
2600/21/14/53

I currently now can go 1500 rpm's and create chlorine with my swg. I can still hear some water sloshing at the inlet/outlet of the heater though. Can't believe the crud after 1.5 months.

Brent,

For reference, when I run at 2800 rpm my filter pressure is about 12 lbs. But I have no heater and a much less complex plumbing set up.. Based on that, it sounds like you are about right...

Let's see what James has to say..

I honestly thought your filter would look a lot worse...

Thanks,

Jim R.
 
It looks like he gave it a backwash before taking it apart. That will clean some DE and dirt off.

It still looks pretty bad. It's not always about how thick the dirt is, but how dense it is.

The flow is still a little bit low for the speeds.

I'm still estimating the suction side head loss at about 7 to 8 psi.

That's about what you would expect if the suction was a single 100 foot run of 1.5" pvc pipe.

So, there's an issue on the suction side.

A single run of 2" pvc would be about 2.3 psi.

At 53 gpm, the filter pressure is still too high. There's too much restriction on the return side.

The in-line tab feeder is part of the problem. It narrows down the flow pretty bad.

Under better conditions, I would expect about:
1300 rpm = 25 gpm
2150 rpm = 55 gpm
2600 rpm = 75 gpm

Brent, can you get the readings at 1500 rpm and 2350 rpm?

Did you check the cell?
 
I did not backwash before cleaning.
I did have a lot of plaster dust and plaster pebbles at the bottom of the filter. When I had everything out, I scooped most of it out. rpm/gpm/pump psi/filter psi:

1500/16/7/6
2350/46/17/12

I would say maybe 50 or so feet from pad to far end of pool/spa. I went to the local pool store for the DE scoop. I put in 6 lbs of DE which should be correct. As you can see I did redirect some water to the spa so I can get some spillover at 1500. That does lower my gpm because if I have 100% at the spa, 1500 rpm's will not create enough flow for swg.

In the previous picture, the valve is set to backwash.

I think that the flow is less than it should be. I think that the suction side and pressure side are both presenting too much restriction.
 
Brent.

What I believe that James is recommending, and what makes the most sense to me, is to shut off the water going to the Spa when in the pool mode..

In the Pool mode all the water should be sucked from the Pool and returned only to the pool.

In the Spa mode all the water should be sucked from the Spa and returned only to the Spa

In the Spillover mode, your automation will rotate the valves so that all the water is sucked from the Pool but will return all the water to the Spa.. Obviously this will cause a big spillover.

Instead of running water into your spa all the time to keep the water fresh, you just schedule your automation to go into the spillover mode a couple of times a day for 20 minutes or so..

Am I correct in saying that when you close the manual valve in your last pic that the water going to the Spa increases?

One final thing and I'll leave you alone.. :p How many return eyeballs does your pool have and what size is the hole in the eyeball???

Thanks,

Jim R.

I only have pool and spa mode automated. The two automated valves are to switch the pool/spa suction and the spa (left) and the pool/spa (right) returns if that makes sense. For increased spillover I have to manually turn that valve to shut off pool returns. I have six eyeballs in the pool, but not sure of the size. Correct when I close that valve I get increased spillover.

Brent,

If you have the EasyTouch you have the spillover option... The spillover uses the same two valves that rotate to Pool and Spa.. It just rotates them so that you suck from the Pool and return water to the Spa.. It is a built in function. It may not be programmed, but it is there..

The reason that I asked about the eyeballs is if they are small that will cause too much back pressure, but I doubt that is the case if you have six of them. You could just temporarily remove the eyeballs and see what difference it makes on the flow.

I assume you know for sure that you have flow out of all six of them... ?

Thanks,

Jim R.
 
The hole in the eyeball looks too small. I would suggest a larger diameter.

Something really odd, if you zoom in on the eyeball, it looks like there is an actual eye staring back at you.

Please don't assume, because you would be wrong, lol. I will check. Also I have seen the spillover by th ge "V" button on the ET8, but like you saidit must not be programmed.

That is freaky, does that mean I have seven eyeballs?
