Hose bib connection on Waste line?

[GreenLight]

How would I go about connecting a hose bib on a 1 & 1/2 " waste connection?

Well, a reducer bushing with the appropriate thread would do but you have to be careful as reducing the pipe down to a 1/2" or 3/4" hose bibb will be very restrictive on your pump and filter.

At most local home improvement stores you should find the parts necessary. Although like Sean noted 1.5 inch to 3/4 is about a 4 times reduction in flow rate, not to mention hose bibs often start at 1/2 inch or smaller at the valve. If your going to try it once you get to 3/4 or so add a "T" and put two hose bibs on it, that way you can at least run out 2 3/4 inch hoses, about 1/2 the flow of a 1.5 inch.

What are you trying to do? Maybe we can help beyond what was said above if we know the purpose.

I did find a brass hose bib with a ball valve at home depot that we use on the backwash for our pond filter. Much less restrictive. This allows us to hook up a hose and water plants when backwashing. This is on a small submersible pump that only moves about 1/4 the volume as the pool pump though.

I am trying to figure out how I will backwash and drain if I buy a new filter (don't even ask me about the ancient DE filter that I "inherited" with this house and pool). I am thinking of a Hayward top-mount sand filter, or a cartridge model. There is no septic drain anywhere near the pump and filter, so I will have to use a hose somehow to backwash. I could not find any PVC parts at Lowe's or Home Depot that would adapt 1 1/2" down to 3/4" (which is the size of my garden hose, I believe).

Thanks for whatever advice that you can give.

Most people either hard pipe the bachwash outlet into a drainage tile or into the sewer or use a roll-up 1.5" backwash hose (you can buy them at HD, Lowes, Pool Stores, Wal-Mart, etc.) just rolled out onto the lawn.
