I have to replace my washdown pump. I thinK It was not winterized properly since I just used it for the first time this season yesterday and it just spits air. I’ve been using a Pentair Sureflo Pro Blaster II 12 v, 5.0 gpm 60 psi 14 amp max which I installed about 12 years ago. I’ve been happy with it, but would not mind a little more power.
When I research the internet, I find some nice Jabsco models but they require more amps and I do not want to change my circuit breaker. I currently have a 10 amp breaker and the Shureflo has worked fine even though it’s rated at 14 A.
Thanks. That is what I am going to do. I just ordered an Underhill Magnum Stinger Fireman Style nozzle NG400 from Amazon for $30. I am reordering the same pump from Crook & Crook Marine in Florida. They had the best price for $300 + tax including shipping. I find it interesting that it calls for a 20 A breaker, but my old one has been working fine using a 10 A breaker. If the new one doesn’t work with the 10 A I can always change out the breaker to a 20 A. The max draw of the pump is 14 A and it must not actually draw the full 14 A
Thinking about this a little, I bet your pump has been cheating its rating because you have not used the pump in continuous use for long enough to allow it to fully warm up and have a larger resistance.
If you do change the breaker you should also up the wire guage to the pump, otherwise you could possibly cook your current wire if it cant take the higher amp load. (Doubtful but I have to say it).
I have been looking at washdown pumps too… my plan is to install a water maker under my v-birth and want to use my washdown pump as a boost pump for the main water maker pump. I never knew there were so many options.
It would be a royal pain to increase the size of the wire from the breaker to the pump. I am sure it could be done, but it is a long run through hidden passageways. Hopefully this will work since I am replacing it with an identical pump which I originally purchased in 2013. It served me well, but is not the pump’s fault that I forgot to winterize it. You are correct that I do not run it continuously for long periods of time. I have used it for occasional washdowns, but mainly use it to wash mud off the chain and anchor. We do a lot of anchoring. I guess the worst thing that will happen is that I may have to reset the breaker now and then.
