I was getting ready to do my annual spring deep cleaning of the sand filter, and managed to pull the standpipe and laterals out along with the multiport. The o ring had a pretty good grip on the standpipe. Everything came out intact, but now I have to get it back in.
1. Is there an easy way to do this with the sand in the filter, or do I need to remove the sand? I'm guessing I need to remove the sand.
2. Seems tedious. Any shortcuts, like using a shop vac?
3. Since I'm already pulling the sand out, should I just put new sand in? I'm in the "sand doesn't wear out" camp, but just wanted to check.
4. Any maintenance I should do, while I have it out and apart? I've deep cleaned the sand, and inspected the laterals and multiport.
