Ok, I checked out the Hayward true union and the jandy never lube gate valves that were recommended on this forum. One is a ball valve the other a gate valve. Question is, which is better in your opinion? Any thoughts on these two would be appreciated.
Also, I have a cartridge filter, how often should these be replaced, One is a couple seasons old the other one season old, I currently switch them out every month or so. Is there a point in time when the filter is no longer functional. I do clean and inspect them regularly.Any thoughts on this would likewise be highly appreciated.
