    Should I plumb back wash pipe

    Hi,

    Now that I got some of my previous problems solved with the help of this forum, I'm looking to connect the backwash output of my filter to a drain. It currently dumps all the back wash onto the concrete pad that all the pool equipment sits on. The question I have is should I also route the filter's plug to the drain. For example, lead the backwash pipe to the back of the filter where the plug is. Add a basket/gutter of some sort so when I remove the plug, the waste can drop straight in. Then continue the connection to my sewer drain. Here's a pic of my current setup, which I inherited.

    Needless to say, it gets very wet, messy and dangerous when I backwash or clean out the filter.

    Thx.

    Worked for me, but here's another site.

    The ftp site asks for a userid and password when I try to view those pictures.

    I'd highly recommend plumbing the backwash line. It's a good idea to add a sight glass to the line so you can see when you are done and also so you'll notice if there is flow there when there isn't supposed to be.

    Plumbing a drain for the filter drain would be nice, but it's hard to say if it would be worth it. My equipment is indoors, and I put a drain in the floor near the filter. I only drain the filter once a year, so I can deal with a little water then.

    I'll keep in mind the sight glass. Right now, I was planning on connecting a flexible hose from the back wash line going to the back of the filter then out to my drain. Hope the picture makes more sense. I've had to drain my filter about 5 times in the last 8 months due to various reasons.

    Re: Should I plumb back wash pipe

    At a minimum, get a backwash hose so all the backwash water isn't at your feet, but plumbing it to a drain is better still. My filter drain plug is not plumbed to a drain - I only empty it a couple of times a year max, and can deal with a filter tank full of water. I couldn't backwash right at my feet, though...
