It wouldn't click on and off like it was supposed too,and it's like i wasn't getting any power, at first I thought it was loose wiring,I would shake my pump alittle and the relay would click on until I fully closed the ball valve again stopping the pump thats when It wouldn't click back on without vigoris shaking.......(this problem happend at like 4:00 in the morning) I felt it getting hot and figured there had to be some type of switch inside, found the switch called a thousand people and found a place outta texas that sells them. The place is Mouser electronics.

It's kinda hard to explaing but if your pump is stuck in the on or off mode or maybe flickering on and off that might be your problem unless there is air in the inlet line on the pump and that would also cause it to not shut-off aswell....

I use a Y connection on the inlet of my pump so I can easily change from chem to straight water and also one on the outlet to let any air escape that's built up before my hose reel, For some reason it primes better with the Y on the outlet I will take some pics and show ya.

Chuck, those are Omron Limit Switches (part # V-15-2C26-K), not relays.  I also buy them from Mouser Electronics.  You can get 25of them @ $2.17 ea.   

The reason they burn up is due to the repeated cycling of the pumps.  This creates heat which burns up the contacts within the switch.

 

Chris, the Flo Jet Pentaflex does not have a built in pump bypass in it.  Scott Davis told me that and I doubted him.  A pump with an internal bypass runs all of the time.  This pump cuts out just like the Delavan at a preset pressure.  I called the ITT factory, spoke with an engineer, and confirmed my suspicion.

I see. I have had very few problems with the 5850 pumps I use. Usually, by the time a problem comes up, it's about time to change it out anyway. However, I have had a couple quit prematurely and in those cases, it would be nice to have one of these limit switches on hand to try switching out. Where are they located? Is it a simple replacement?

PS: If you buy the 25 at a time, would you care to sell 2 of them?

Thanks,

Chuck

I thought the same thing when I first heard of the Pentaflex and the bypass, I'm no certified engineer but think like one and also figured if theres a bypass it would build up pressure and instead of shutting off, the bypass would alleviate the pressure an continue to run (kinda like what I hear cycling when what I suspect is air in my system)

I'm lookin for where it says theres an internal bypass with the pentaflex. To be continued....

 

BTW still wonderin if the accumilator is really needed, helpful or should I remove it and set it up on a smaller gpm pump ?

I ve had my all flow pump for over 2 yrs now with absolutely no major problems and i can put any size nozzle i want and get about a 45 ft stream to a fan tip.

Here are the full flow Y's that I was talking about

The idea is fine-I have had that setup in the past, but using PVC.

Just a few tips from my experience.

#1.Those Y's are corroding and if used on the intake side, will suck aluminum pieces into the pump and kill it before long.

#2. the corrosion will eventually make them literally fall apart and pump SH all over, while you are on a roof.

#3. I had that "pump in a box" setup and felt it was just making the pump run hotter than needed. I liked the setup I had otherwise-just not the pump replacements.

Last thought, pumps last the longest if set up standing bottom side up-with the electrical part on the bottom-like this.

What Chuck is saying is true.  Pumps in a box will overheat the pump and always mount them electric side up.  This is what my pump setup looks like.

WOW! That's a beautiful rig setup you have there Marcus! 

I used to set my pumps up the "logical looking" way-electric side up.

However, that leaves any SH leaks that occur, to run into the motor/armature and once in there, it's a gonner.

Now I mount them upside down, any leaks get into the replaceable electronics instead.

Now, my pumps last up to 2 years. Of course, if you never get any SH on the pump at all, it won't matter. Putting it in a hotbox will!

I work my stuff so hard, it don't stay looking too pretty!

Mine is upside down protecting the motor of the pump just in case of leaks so it doesn't fry my motor......I've also never really had a prob with heat just leave the door open on my box, I think it would go faster sitting in the straight sun....... And the Y's work for me for now, till I feel like changing it up again. This set-up works great for me and I have no problems when working, very easy truck to work out of for me.
