I'm a total newbie but trying to learn (moved into house w/pool last August). We have a Jandy Ray Vac cleaner, and tonight I decided to look it up. Pool is 12 years old; not sure how old the Ray Vac is. Tonight, I read the owners manual and found out several things that it says not to that I have done. The one thing I'm most concerned about is that today I backwashed the pool's sand filter and then drained more water to waste (we've gotten about 3 inches of rain since opening the pool this week) since the water level was high. In the Ray Vac manual it says "before cleaning main filter, be sure to turn the Jandy 3-port valve so the line to the Ray-Vac is closed." Oops. Didn't do that. The Jandy valve was open the whole time I was backwashing and draining. Could I have damaged anything on the Ray Vac or the main filter?
Also, just in general, should I take the Ray Vac to a pool shop to have it looked at to see if any parts need replacing? It's doing its job just fine.
Thanks in advance for any advice.
