Use a PVC pipe to couple the valve and the pump together (Image 2).

Step 3: Attach the Supply Lines

Rub petroleum jelly on the o-ring to ensure the seal (Image 1).

Place the supply lines onto the pre-plumbed fixtures on the floor, and tighten with a spanner wrench (Image 2).

Rub more petroleum jelly on the o-rings of the transition elbow, and tighten it onto the supply lines (Image 3).

Step 4: Install the Faucet and Drain Basket

Attach the faucet to the elbow, tightening with a wrench (Image 1).

To install the drain basket, wrap teflon tape around the threads to ensure a tight seal (Image 2).

Apply plumber's putty to the underside of the drain (Image 3), and push it into place in the tub.

Use a star wrench to tighten down the drain basket (Image 4).
