Hose bib connection on Waste line?

[Poolsean]

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.

[MarkC]

When you backwash you want the full flow of the pump to be able to go to waste. If you restrict the flow with a hose your backwashing will not be nearly as effective. The roll up 1.5" hose is deffinately the way to go.

In post #5 you kind of imply you want to dump the waste into a septic system? You really don't want to do that simply because the quantity of water is not desireable. If you mean a municipal septic, that still doesn't make sense unless there is some 'STUPID' code that says you can't dump to a storm sewer or even on your lawn. As a modification of MarkC's comment about the rolled up waste hose you could even punch holes in it and seal the end to distribute the dump over whatever length you want.
