shurflo waterpump leak

[saltyrob]

Hi Folks

Its all niggles at the moment. The Shurflo domestic water pump has developed a small leak,( drip). Does anyone know the likely cause and can the unit be repaired,

Many thanks

Surflow pumps are fully serviceable. You don't say where the leak is coming from. Maybe just the hose connection? Tighten the jubilee clip and/or wrap a bit PVC tape round the outlet pipe if the hose is sloppy and then tighten up. The pump assembly itself is replaceable and just screws onto the motor. The bits are expensive but they last for ages. We had one for two and a half years constant liveaboard with high water usage and it was several years old when we started. Our watermaker pumps are Surflow and they go on for hours every day in the summer.

After 12 years my Shurflo developed exactly the same problem at the beginning of this season! I contacted the original UK agents(no longer) in Norwich who advised me that the most likely cause was a failed diaphragm. Unable to undo the screws holding the pump to the motor, due to corrosion, I decided in the end that a new pump was the way to go. Good luck if you decide to service it yourself.

Best wishes, Nigel

Could it be from the - easily replaceable - hose connector(s)?
On my pump I found that a leak was due to the O-ring seal being a bit dirty.
Taking it out, cleaning it all thoroughly and replacing fixed it.

To get the hose connectors out there is a - not very obvious - sliding lock which you slide away from the connector which then just pulls out.
The whole connector with O-ring is available as a spare part. It is identical to Jabsco, and I got some from Fox's. I had broken one connector when trying to get a manky old pipe off.

Servicing a Shurflo pump is not difficult and usually produces good results. Three things to look out for: first, follow the instructions exactly as stated in the pack; second have exactly the right size allen key specified ( one eigth of an inch if I recall correctly - it is American); finally do not tighten the main bolts too much, they strip rather easily!
Good luck.

I had this last year and it was just the diaphram needing replacing. £20 for the part from the local chandler. It is a dead easy job, about 15 minutes although it depends on how accessible the pump is. No special tools needed, just a phillips screwdriver.

Just realised I have a Shurflo pump, not a Flojet /forums/images/graemlins/blush.gif

So ignore my earlier post.
