Fresh water strainer location
On our TT24 the fresh water tank, the water pump, and the strainer/sight glass are under the passenger side bed. The pump, strainer (that has a sight glass and is between the tank and the pump), and the tank valves are accessible via the removable access panel below that same bed. Be sure to shut off the valve between the tank and the pump before removing the sight glass/strainer or you will have water from the tank coming your way! And, once the sight glass/strainer are reinstalled you can turn the valve back on. It isn't unusual to see plastic shavings inside the strainer screen even after a period of use.
Now, enjoy that rig!
