Had an aggrevating problem develop today. Some piping from the outlet of the pentair multiport (50181212) cracked and now there is a steady leak. While shutting down the filter to remove the piping I omitted closing the multiport and some of the D.E. went out into the pool through the skimmer, drains and return piping. I emailed pictures to poolforum AT gmail DOT com of the broken piping if a moderator could add them that would be great.

1) I realize I need to vacuum the D.E. from the pool, but will this mess up my water chemistry or is it okay in there for a day or two until I can get the proper vacuum head and tubing?

2) Can I replace that specific piece of piping including the cracked nut, or does the entire multiport have to be replaced? (pool service guy said the whole multiport has to be replaced)

3) How much hose do you think I should purchase for the vacuum?

4) Anything else I'm missing or need to do?
