Plumbing help - stepping up or down?
I ordered the Whale Gulper IC for my forward head, and it arrived today. I've looked through the manual and I understand installation, it's pretty straight forward. However I have an issue with the two way manifold.
My sink, and shower (2 drains), all connect to one hose via PVC tee's. So I have a 1" or 1 1/4"ID hose coming from those drains. The other line that I have is a 3/4" coming from my A/C condensation pan.
The two way manifold on the Whale isn't threaded, so how do I step up to the larger hose size from the shower, and step down to the smaller A/C line? I know I'm going to need some kind of barb fitting, I just don't know what's the best option.
