PB says I should run at 2600 RPM's

Brent,

What is the second VS pump for??? Is it dedicated to water features or is it also used for the Spa?

I ask because I agree with JamesW... no matter what the flow, in the setup shown in your pics, all the water is being sucked from your Pool and is being returned to the Spa.. it has to overflow.. unless there is another path back to the Pool... :confused:

Also, if both valves rotate 180, then you're only pulling from the spa and only returning to the pool.

That would cause the spa to drain and the pool to overflow. This should never happen.

You should have Pool Mode, Spa Mode and Spillover.

Pool Mode pulls and returns only to the pool.

Spa Mode pulls and returns only to the spa.

Spillover mode pulls from the pool and returns to the spa to overflow the spa into the pool.

The second pump is for the water features only and is the exact model of the main pool pump (Pentair VSF). So the pool and spa use the same pump which is the one on the right side of the pictures. I looked at the automated valves last night and they are not in the same position as the pictures I put up yesterday. Both valves face the same exact way, which now the close tab are on the left side. This closes off the spa suction and closes the spa return.

See my reply above, but the pool mode does create overflow if the RPM's are high enough. I have never used the spillover mode so I cannot comment what that does yet. I will try it out tonight and let you know.

Ok, so I suspect that the return on the right with the check valve goes to the spa.

Did you ever check the filter pressure and the pump pressure and flow rate?

So the check valve at that location is good, bad, or WTH? I did not get the reading yesterday but I will get that value at 1300, 2150, and 2600.
 
I'm not sure why they plumbed it that way. Maybe to create some flow to the pool and spa at the same time?

I would put both spa returns on the spa side and just run spillover periodically to get some spa circulation.
 
Brent,

Looking at the pics of your plumbing after the automated Return valve, the water can either go to the left and the Spa, or to the right and through your tab dispenser and then down through a manual valve or down through a check valve...

Logic says that if your Spa overflows with the Return valve in the Pool position, that either the manual valve or check valve after the tab dispenser has to be sending water to your Spa...

If the water going to the Spa goes through the manual valve, you can simply shut if off... If the water going to the Spa is going through the Check Valve, then the easiest fix would be to swap out the guts of the check valve with a regular Jandy two way valve and turn it off.

Do you have any idea what the manual valve after the tab dispenser does??? If it controls the water returning to your pool, then it needs to be set to full open 100% of the time.

I'm thinking this is all tied into your salt cell's low flow issues...

Thanks,

Jim R.
 
I was checking things out last night. The pool return valve in the shut position will send all water to the spa. In the open position it will send water to both pool and spa if enough rpm's open the spa check valve. I currently have the valve halfway between open and close to send water to both pool and spa at lower rpm's. I have had the valve after the dispenser open 100% the whole time except last night. Today not even 2150 rpm's was enough to create enough flow for the set. Still have not recorded pressure yet.

22 gpm at 2600 rpm indicates a serious problem.

Is the pressure the filter pressure?

Did you check pump pressure?

You have almost complete blockage of the suction or pressure side.

I think that the suction is blocked and the filter needs to be cleaned. Check the cell screen for blockage and the cell for debris or scale.

What are the pump pressures at those pump speeds?

What are the power readings at those pump speeds?

I got the pressure from the top of the filter.
Not sure how to check the pump pressure.
My start up date was 4/23/18, do you think it already needs to be backwashed?
Cell screen on the SWG?
Power readings are as followed in RPM/Watts/GPM
1300/87/1
2150/396/13
2600/763/24
 
IntelliFlo VSF Variable Speed And Flow Pump (Keypad Overview) - YouTube

Near the end shows pump psi.

The filter pressure only shows the pressure side pressure. The pump pressure is the pressure side plus the suction side.

So, if we subtract the filter pressure from the pump pressure, we can estimate suction side pressure.

In any case, the pressure side and the suction side are way too high.

At the listed speeds, your flow should be much higher.

The suction needs to be evaluated with a vacuum gauge.

The filter should be disassembled and cleaned (not backwashed).

The cell has a screen at the inlet. That should be checked for debris.

The cell should be checked for scale and debris.
 
Brent,

The next time you are out by the equipment pad, do me a favor and see if you can find a part number on your multiport valve... and let me know what it is...

I take it your filter has never been backwashed or broken down and cleaned since you opened the pool??? I would say under normal conditions this would be fine, but something is obstructing the flow and the filter is as good a problem-child as anything else.

Thanks,

Jim R.
 
The multiport looks like a 261152 (DE) and not a 261055 (Sand).

The DE multiport has the sightglass pointing away from the filter, whereas the sand multiport has the sightglass pointing toward the filter.

The DE multiport has the filter position away from the filter whereas the sand multiport has the filter position near the filter.
 
James,

I'm sure you are right, but I was just grasping at straws... Something is wrong, but it is not obvious to me about what it is...

It just seems to be a filter issue to me.

Jim R.
 
For the filter pressure to be 20 with only 22 gpm, there is definitely a problem. 22 gpm should barely move the needle on the gauge.

I'm also estimating about 8 psi on the suction side. So, that's also way too high for 22 gpm.

I suspect that the total system pressure will be about 28 psi. The pump pressure will help diagnose the issue.
 
Yeah I just came home to put somestabilizer in it. At 2150 rpm's I had 5 gpm. I shut it off at this point. I cleaned out the basket prior to that. I did notice like it might be where the connections are to the heater because of the sounds. Only thing I can say is it isn't full of water at that point because of the sounds. I just saw the video but this pump is hooked up to the automation box and can't get that info.
