DIY Muriatic Acid Doser

Uh, I'm not seeing an injector. The part that fits into your plumbing pipe, that you attach the pump to via the 1/4" tubing. Is the injector included?

The injector should have threads. Those threads fit into either a saddle or a PVC tee with threaded adapter.

If you go with a PVC tee, then you have to find a place for it and cut into your plumbing. Here's what mine looks like. The injectors are usually black. I painted mine for a little extra UV protection. I also covered all my wires and tubing with that split wire loom stuff:

The saddle just fits over a PVC pipe, into which you drill a small hole. Then the saddle seals up to the pipe with a rubber gasket and some big hose clamps.
