    Surprised that nobody has answered. I'm not really sure that there is a proper method other than removing the cone on the back of the pump and looking for water.

    That and pull the pump to feel for seal friction, check for bearing play and check for smoothness of rotation. Lube the splines while at it and pull the impeller to inspect the circlip area for corrosion. Pretty basic shit.

    Thank you. Yes I guess removing the pump would be the most logical.

    I pull my pump every 40-50 hours. At 15 hours I would leave it be and do it in the winter.

    Yes, this is why I suggested just checking for water. Very unlikely that there is a bearing problem at 15 hours and one year old.
