No water getting through water pump - any ideas?

[RosieP]

Hi,

 

I've started a new topic as I had originally asked for advice about a burst pipe but now after some helpful advice I've found that isn't the problem its the water pump - water is going into the pump but nothing is coming out, despite the pump being activated.

 

You can guess my next question - what is likely to be wrong with the pump? It is a SHURflo diaphragm pump - Aqua King. Looks to be 6 years old. The problem is now occurring after leaving the boat cold and drained for a week in freezing conditions.

 

It has recently been playing up - takes about 5 seconds from tap opening to pump kicking in. It was getting so bad we had to start running bath tap (which is lower) in order to get water out of the kitchen tap. We are in a soft water area so possible limescale build up.

 

All ideas would be very much appreciated.

 

Thanks

Fit a new pump if you are certain the water supply to it is flowing freely. They are only about £60 on ebay and £70 (IIRC) in Midland Chandlers and you could spend £30 on bits trying (and possibly failing) to fix the old one.

I have just fitted a new diaphragm to my Flowjet pump for £20, when I get home I will be ordering a new one, because it still leaks.

Back to your problem, lots of pumps have a strainer on their inlet something like this. Check its not blocked.

Yes check the filter/strainer almost certainly the problem. The couple on the boat next to ours had exactly the same issue and when I removed the filter it was clogged with rust particles from when they drained the tank. It doesn't take much to block the filter.

Air Lock?

 

I haven't read the other topic referred to. When I've let the tank run dry a couple of times Ive had to clear an airlock in the pipe work.

Yes and you get one free in the box when you buy a new £60 Shurflo pump!

Not one in the £80 Shurflo. Ive bought 2 Shurflo pumps in the last month for people and there was no sign in either. £6.90 from Sileby Mill
