C**P tank full - won't empty - Help

[Jegs]

The Sealand tank monitor is indicating full [I suspect the high level led has failed] & the extraction pump only pushes air. The circuit diagram shows connections to both float level [high & full] switches and I suspect that lifting the tank cap might cause the float to drop & enable the pump to operate as desired, but life's rarely that straightforward. If anyone has any experience of dealing with this problem, I should be much obliged for some advice.

Hopeful thanks,


John G

Would a gentle tap with a small hammer not help loosen the sender?
On another boat the fuel guage would stick when we were heeled, but a very gentle tap to the top of the tank on the plate holding teh sender would set it sliding back to the level of liquid.

And don't do what a friend of mine did. Take a stick to an unidentified blocked orifice on the boat whilst standing underneath when it was propped up on the hard.

Thanks to all of you. The tank was empty & can still used [even more phew! than you can imagine]. I shall a tap, but they installed the seating after fitting the tank.
