My Shurflo gave up the ghost yesterday after 15 months solid use, is that about normal in your experience?
Yes this quite normal for a Shurflo. However so is them lasting for 4+ years, it seems to be completely random!
I know of people using microbore hose, shurflo pump, and no varistream and they have lasted for years. On the other hand I know of those who have used varistreams, standard hose and they have lasted a much shorter time.
I have heard (williamson pumps may correct me) that Shurflo pumps are only warranted when with used with an electronic flow control.
I have always used a Flojet pump with no flow control at all. So far I have used 7 of them in our vehicles, trailers and trolley.
2x60psi which served for 4 years on a twin pump set-up, 1 pump per 100m of microbore. (they are now in the vehicle as fully working spares)
1x 100psi to replace the above set-up now about 1 year old. I did have to fit a new pressure switch as the one it came with was faulty.
1x 60psi which was on a 2x 60m microbore set-up this pump lasted for 3.5 years on 5 days a week use, it died of old age (started leaking fluids!)
1x 100psi to replace the above set-up, now 1.5 years old.
1x100psi on a trailer set-up running 2x 100m of microbore lasted for 4.5 years before running noisily and pumping slower.
1x 100psi to replace the above set-up now on about 2 years, I have had to hit the pressure switch a couple of times when it has stuck in the off position!
1x 60psi on my original trolley set-up 6.5 years ago with 1x 60m microbore, I only used this for 2 months (do not like trolleys), sold it to a mate who used it for 3 months before selling it to another mate who used it for 4 months who then took the pump out to use in a van, he then sold it on to someone else who is still using it on a part time basis.
All of the above were Flojet pumps, with pre-pump strainer, with no electronic control. I use flow valves on my poles. All I have done to them is set the pressure switches up to match my exact system.
