Pump up the ...

So, today we were doing more furtling under the hood of Brrenda the Bongo. When we were away last weekend we couldn't get the tap to work, so today we put more water in the tank, watched as it flowed out of the top, emptied most of the water out again, and then discovered that the pump filter was cracked, meaning that the pump was sucking air not water. :(

I hope the replacement filter arrives soon...
