Aaarrghhh!!!!
It always happens when you are about to leave to go somewhere!!!
Just gave the Shurflow for my water heater in m y 80 Series a bit of a tickle to make sure it was working OK, only to find that it won't suck water up from the bucket on the ground.
If I put the bucket up at the same level as the pump it gets water through, but spurts and f*rts, but in a pinch it could be used.
Now .. this pump has only been used for one shower since I installed it around July/August last year, so I am thinking that something may have deteriorated through "no use". Not sure about warranties, but at the moment I just want to get it working properly.
So, any advice from those who know something about these Shurflows would be appreciated. I dont even know how to pull one apart, which will prove interesting.
Thanks in advance.
Jack

Jack,
Do you have a small filter in the suction line?
If not it may pay you too as just a tiny bit of rubbish under one of the valves may reduce its sucking power, which by the way isnt great, I use a small garden dripper filter on my shower unit pump. You may have to sometimes lift bucket for a moment for it to catch its breath.
These units are as simple as to pull apart, just undo screws at front and you end up with valve body in your hand and diaphram still connected to pump motor.
Forcing water through it may shift any rubbish in the valve.
Word of warning , DONT apply to much pressure to suction and discharge hose tails as they snap off easy and then a whole new body is required.
My experience of using these units for work for many years, is they are ultra reliable.
Have a coouple that have pumped chemical spray daily for 6-8 months of the year for 7-8 years without failure.
Cheers Pesty

Hi Pesty:
There is a small filter, which I have cleaned out in case that was the problem. No joy there. but I will take on board your thoughts about they being easy to pull apart. That can be on tomorrow's agenda.
It worked great the only time I used it (not long after I installed it) so I am thinking it is gunk somewhere along the line.
I will call Shurflow early then set to work. Going to be away for a good while, so I will probably need a bit of a clean up .. better goet it working. : )
thanks for your help.
Jack

Jack,
I had a few early probs with my twine too....the pump wouldn't suck.
John Twine sent me a new diaphram for the pump (easy to fit) and that worked okay; but they do dry out if not used regularly.
Anyway still had some probs again another time and, same as you, if I could get the feed water high enough to gravity feed, all was ok. That was no good in the long term so I bought a little squeeze pump like they use for pumping fuel between a fuel tank into a outboard motor. I mounted that in the red Woolie's box/crate that i use for showering. I also mounted one of those in-line black coloured filters from a garden irrigation set-up. These both "live" in the bottom of the crate and have a 90o elbow joint to which is attached a short length of green garden hose (just enough to reach the top of the crate) and a male half inch garden hose fitting on top. This whole thing is held in place by a screw-up hose clamp through 2 slits in one corner of the crate. The hose I use is mounted permanently under the bonnet on the pump (coiled up on top of air cleaner) and has a female hose fitting on it.
When it's time for a tub, I fit the hose fitting onto the crate full of water, give the squeezy pump a few pumps with the Shuflo motor running and it all works ok. It still farts a bit, but I will eventually get around to finding out why that is.
I think the secret is to run the pump very often (like once a week).
Cheers
Roachie

It sounds like you have an air leak on the suction side of the pump. To
test this, get a bucket of water and put the suction hose and shower head in the bucket. If there are bubbles coming from the shower head, then the air leak is in the suction side. To fix this, connect a single piece of hose to the suction side of the pump (ie with out any snap fittings or a filter) and see if you still have the same dramas. I'm sure the pump will prime and lift water for you if you bypass the snap fittings. Most problems are caused by snap fittings on the suction side. Theses fittings are renowned for it. By putting a single piece of hose to the suction side usually is the best
test.
I would get rid of the snap fittings and buy screw type or air type fittings but make sure that the filter is still used. Some times the thread on the filters leak air, so put some thread tape on the thread and tighten.
