Clogged return?

[sherryandnate]

We had pool water solar panels installed a few weeks ago. I have noticed that the return that has the furthest pipe run, is not pushing even a quarter of what the other ones are pushing. We have 3 returns in the pool and one in the spa with spill over water fall. My guess is some random piece of gunk or pvc shavings from the construction got lodged and has decreased the flow?
Is there anything we can try on our own to get water flowing thru it again?
When the solar turns on it gluggs and chugs out big bubbles. While the other returns shoot bubble streams out.

S&N,

I doubt you have anything wrong... Water will take the path of least resistance, so it will basically go out the two returns that are closer to the equipment pad, leaving less water pressure at the end of the line.

As a test you can temporarily plug the first two returns and see what happens to the last one.

A fix may be a simple as adding smaller eyeballs to the first two returns.

Thanks,

Jim R.
