See, I have a cartridge filter instead of the more traditional diatomaceous or sand filter. These things require cleaning and replacement. Cleaning can be as often as every couple of weeks in dirty weather or a few months when there's no sand storms, bug migration, tree blooms, or dirty dogs to mess it up. However, this year I've been pestered by caterpillars, crickets, beetles, frogs, sandstorms, and tree blooms such that I've had to clean the cartridges several times. Add to that the calcium carbonate snow that accumulates due to the chlorine generation and summer has been a pain in the pool department.
I decided to get a pre-filter to get rid of some of the crap to keep the work load down. I got one of these:
I used the glue technique I learned when I was working on the solar heater. I found out that to get the absolute best seal, forget the normal PVC cement and purple primer, go directly to the blue 'Red Hot' cement and forget the primer. That little trick took me almost a week and calls to the pipe manufacturer to discover. Here's a picture of the filter in action:
In all honesty, I can't recommend this device for other people yet, I haven't had enough experience with it yet. However, if the accumulation of particulates is any indication, this thing works. I'm going to watch it like a hawk for the next week or so (naturally, it's new and cool) then determine if it is actually doing the job it's advertised to do. I'll hook up the vacuum head and clean the pool and see what happens when I flood it with the stuff that hangs around on the bottom of a pool in the desert; that should be a good test.
At any rate, stay tuned, I should know more in a few weeks.
Edit: I've had some experience with it now, more information here <link>
