Rule Mate 750

Hi
My rib has one of the above bilge pumps. Not been a problem for me up until today. When I washed the boat out the pump came on and would not switch off. It is the one with the internal float. I have dismantled it and there is no obstruction, however it still strays up as soon as I reconnect the battery. Is there a fix for this or is a replacement the only option?

Thanks for your help in advance

Have you given it a shake to make sure the float is free to move. Mine tends to jam up at the start of each season having sat in the off position over winter. I presume it's not one that runs for 10 secs to clear the pipe and you're not leaving it long enough.

I don't know about fixing yours, but when mine packed up I replaced it with one of these whale supersub. No float switch to go wrong, has worked perfectly well for me.

I have taken off the bottom
Plate and cleaned it all up. It still starts up as soon as I reconnect the battery. Does it run for 10 seconds initially and then stop? I may need to try leaving it for a bit longer before I disconnect.

The chandler stocks the rule and he whale. Does the whale just sit in the bottom of the bilge? The Rule is mounted about 2 in up on an aluminium strut which makes it difficult to dry it out properly without a sponge!

The whale can sit as low as you can get it. It has to be level because if you lower the scoop end, the sensor goes up and if you lower the sensor end the scoop goes up and cannot suck up as much water.
It has a built in overrun function so that when the sensor tells the pump to switch off, it continues to run for for a few seconds.

Decided to replace the pump. Picked up a new one this morning Had to re do the mounting since the pump design has changed. Wired it in and ... Nothing! The motor was seized. I freed it off with pliers but it still wouldn't work! Disconnected it, return to chandlers, they try it but connect it up backwards and hey presto it runs, BUT won't switch off! Try a replacement and that seems to work as it should so fingers crossed should have it sorted later today.

I'm glad the chandlers is only a few miles away!
