    Adding a drain/waste line

    I want to replace the hose bib on my return? line with a bigger, better flowing 11/2" line. I saw the pics of the one coming out the bottom of the filter housing. I have the same 100 sq ft filter but my heat pump is using that fitting. I have a hose bib in place but little pressure and was wondering if I could use the same line to install a T and ball valve and achieve the same as if I came out the back side of the filter?

    Sounds like something you could do. Any chance you could upload a picture of your equipment so we can see first-hand what you're dealing with?

    Re: Adding a drain/waste line

    The drain is on the dirty side of the cartridge filter. Are you really running unfiltered water through your heat pump?

    If you want a drain, it shouldn't be that huge an ordeal to cut a pipe somewhere and glue in a Tee. Seems to me that you might want to reroute things to that heat pump while you're at it. A picture would help us a lot.

    If it's just for emptying excess water, think closer to the pump. A lot of people have a Tee at the pump output instead of a 90. The extra leg gets a valve and a threaded bushing and a hose adaptor or a faucet. The faucet lets you use garden hose. A larger hose fitting lets you use a much larger hose. I'll tell you from experience, a 2" backwash hose running wide open weighs a bunch and flips around wildly. It's like a firehose.
