Our water pump has been making a strange noise – not really stopping as soon as it should. On closer inspection it has been leaking from the shut-off switch on the bottom for a while. This explains the little puddle of water that appeared on the saloon floor whenever Molia was heeled over.
When we arrived in Portland, the pump completely failed to stop after the galley tap was turned off – so I decided to replace it. We have a few days here to do the work.
The original Jabsco ‘Sensor-max 14’ pump is the 35 psi 12V version, with a flow rate of 14 lpm (litres per minute). Its closest replacement is the Jabsco ‘Par Max 4HD’ with an output pressure of 40 psi – but I do not want to stress our plumbing, so chose the 25psi version that delivers 15 lpm.
The new pump was shipped overnight from the Marine Superstore in Portsmouth – we are very grateful for their efficient postage and packing, so I fitted the replacement this afternoon. Less than 48 hours from fault to finished job.
The new pump is a direct replacement – it has the very similar dimensions (perhaps its very slightly longer), but it has the same plumbing connections and even the same screw spacing!
