Pump Pressure Issues

[GreenTerrorPool]

I cant seem to figure out why I can not get much power anymore to my jets, pool cleaner etc etc
Seems like the power just is down. Any help here?
I have checked:
The filter is not clogged and the cap is on tight
It doesnt appear I have anything stuck in my pool cleaner hose
I do have an issue that the strainer basket doesnt look to get completly full, so getting air in the system somehow (although I have had this before and I still get good power to the pool jets)
thank you all

In a situation like yours it would be best for us to take a look at your water testing results since sometimes that can provide clues before we go chasing mechanical issues. Can you post a set of water results?

Thanks TX, what would water results have to do with my water flow being low. Anyway PH an Chrloine are all good and salt level etc etc

The filter is not clogged and the cap is on tight

"Clogged" is subjective. Flow obstruction is a sliding scale and you indicated you have less flow, not none. It's still possible you have an issue with the filter even if it 'looks' okay. When was the last time you cleaned it? Replaced it? The CS200 filter is smaller than I would suggest for an 18,000 gal pool and would lose efficiency and flow quickly.

I do have an issue that the strainer basket doesnt look to get completly full, so getting air in the system somehow (although I have had this before and I still get good power to the pool jets)

This could be as you stated. How many diverters do you have on your suction side? I couldn't find any photos of equipment in your media. Can you send us one?

Have you purged the air using the relief valve on your filter enclosure? Does it reduce the air in your system and stay improved?

And just for the sake of having asked; what is your pump speed and can you confirm that hasn't changed?

YEs cleaned and replaced recently, I dont think the filter as never had an issue when I ran a very old one for years and didnt clean as much as I shold have

GTP,

The main cause for low flow is almost always a dirty filter. Water chemistry can cause algae, even when you can't see it yet and it can quickly clog the filter.

There is almost never a mechanical issue causing low flow. Maybe the VS pump running slower than you thought, but that is about it.

Clean your filter and see what happens to your flow.

Thanks,
