Subject: Circulation dropped after installing suction vac
Question
New pool owner here. My pool developed a leak which was repaired by professionals just a few days ago. After the leak was fixed, I brought the water level back up to normal and have been running the pump 24/7 to clear some cloudiness that developed. The pump was working normally with good circulation in the pool. Yesterday, I installed a suction vac (Kreepy Kruiser), following all the directions carefully. The vac was operating just fine when I checked it last night before going to bed. This morning, the vac had stopped moving and the circulation of water in the skimmers and from the intake jets is barely perceptible. The pressure gauge is at 25 psi. Normally, it's around 20 psi.
The pool was free of any large debris that could've clogged the lines, but there are lots of trees near the pool, and leaves could've blown in overnight, although there were none in the pool this morning. I suspect the lines are clogged, but I don't know how it could've happened.
How can I check for clogged lines, and is there a way I can clear them myself or do I have to call a pro? Is there something else that could've caused the circulation to slow like that?
Thanks in advance for any help.
Answer
Your lines are not clogged... your filter is. The cloudy water was either due to fine dirt or the start of algae. Both of these will get trapped inside your filter causing the suction to be reduced. You need to backwash the filter. I typically backwash the filter after the pressure goes up 3-5psi. The higher the pressure,the less the suction you will have, the less suction you have the less likely your pool cleaner will work.
Good luck,
Craig
