[Tiara Open] Tiara 41 Open Water in forward bilge

[esf]

I have found that in my boat there is a tank in the bilge that collects water from the wet sink in the helm area and a few other areas yet to be determined. The pump system stopped working and the tank (estimated at 20 gallons) was full so this is where the water in the mid bilge was coming from. does anyone know what the pump on the top of the tank is? It is not working but does discharge directly out of the bilge through the hull.
