I took over pool maintenance on our pool only last August, and thanks to this site all has been going well.
I seem to have a problem now, however, and I'd appreciate some input.
Keep in mind I understand nothing about pool plumbing.
For about a week now, I've noticed that the spa jets are pumping water rather than the pool jets when it should be the pool cycling. It happens on and off. I've tried to study the valve positions to see if anything has changed, but I can't figure it out. I also don't know how to manually turn the valves (will I break them? Does the system have to be in service mode to try?) or which ones to see what's going on. I'd like to avoid an expensive call to the pool guy because I'm guessing that a valve has worn out and it's no longer closing properly but I don't really know. What information can I give you to help me solve my problem?
Thank in advance to anyone who chimes in.
