I am complete my with a wet bar. I had to pipe the water up the wall and to the drainage pipe. What do I need to pump the water up to the drainage pipe.

Randell:

You need a laundry tray pump or similar pump system... see pic. Below.

There are numerous types on the market... I like the zoeller laundry tray pump or the little giant system.

Can check out the zoeller laundry tray pump at Zoeller Corporation

The drain from the sink to the pump needs to have an air admittance valve (AAV.. see pic. Below) piped in relation to the P-trap as shown in my other picture below (see P-trap picture).

The discharge from the pump will need a check valve (see last picture) under the sink and a cleanout installed where you connect the drain line into the sewer line.

The pump you choose will tell you how to pipe/vent the system.

Let us know if you need more information... glad to help...
