I installed an American Standard Hydra 2116 toilet tank with Aquameter Fill Valve. I am having a problem with the toilet bowl fulling up. The first time I flush the toilet, the toilet bowl and tank are full of water. The tank and bowl empty, then the tanks refills, but the toilet bowl doesn't completely refill. I flush the toilet again, the tank empties, but the bowl doesn't empty. The tank then refills, the bowl and now the bowl is full. I flush again, and both the tank and bowl empty. The tank refills, but the bowl is only partially refilled. I adjusted flow rate, and the flush valve float. It looks like the tank is refilling faster than the bowl. Any suggestions. I replaced 2 toilets, and they both are having the same problem.

We're moving our shower from one side of our bathroom to the other. We've decide to put a pre-formed shower stall in because this is only a five year fix. My husband want's to put the plumbing and drain in before we receive the stall. I'm concerned he'll put the drain in and when we get the stall they won't match. We're getting a 36" stall. Can you tell us how he can determine where to place the drain and what the appropriate heights the shower head and the mixer for the water? Hope I'm using the right terms.
