Thanks for that??think I’ll look to upgrade a bitLooks like a cheap pwm motor controller like this: 12v pwm controller
That one says it's suitable for 20A so should be fine on most pumps. One thing to note is that there is no dead head detection on basic pwm controllers. So you are relying on the pumps micro switch to shut off the pump when you close a univalve or tap on your pole. It's the lack of dead head detection that can cause excess current to be pulled through the controller so an upgrade to 20A might help.Thanks for that??think I’ll look to upgrade a bit
The switching current should never exceed 7 or 8 amps though.That one says it's suitable for 20A so should be fine on most pumps.

You are quite right 7 - 8 amps should be fine. Pure Freedom have a good reputation for their trolleys. Only reason I suggested a higher rated pwm controller was that cheap controllers might scrimp on components and 10 amp might be a bit of an over rating or very very short spike. The 20 Amp ones should be able to take more 'abuse' without going pop.The switching current should never exceed 7 or 8 amps though.
I was still using my original PWM controller that came with my first Pure Freedom trolley that was fitted with a 100psi Sureflo up until recently, and that controller was only rated at 7amps max. Only stopped using it because the bolt that held it on rotted in the box and I broke the box removing it to repaint the trolley.
Your right, hose inside the pump box sprung a leakYou are quite right 7 - 8 amps should be fine. Pure Freedom have a good reputation for their trolleys.

Looking at OP image looks more like water damage though but for the price difference between a 10 amp and 20 you might as well have that bit more headroom ?

What’s the point in building one when you can buy one that does all that without the faff of building?I'm glad I designed and built my own trolley system.
Never had to replace anything
Never have air locks
Don't get calibration or dead end issues
The battery is now over a year old
Don't need a trolley to move it because it's built into a trolley
Plus it not yellow and manky blue
You are every manufacturer's dream. ? Buy it and when it stops working throw it away and buy another.What’s the point in building one when you can buy one that does all that without the faff of building?
It's called not getting ripped off. Of the shelve parts. Better quality control. Its stronger.What’s the point in building one when you can buy one that does all that without the faff of building?
Thank you @spruce The most rewarding fact is when customers and and other windows cleaner's ask "where did you get your trolley?? " I proudly say I BUILT THAT" and you see their initial look of NO WAY..You are every manufacturer's dream. ? Buy it and when it stops working throw it away and buy another.
Some of us just like to make our own as it gives us a sense of achievement. If we do buy something we ask ourselves how we could improve it. It's just the way we are.
On another post @Apw1210 mentioned that he was suffering from PTSD. This form of traumatic stress just bubbles under the surface. It never goes away, it's always there. Having a hobby that brings him satisfaction is one way that helps to keep his mind focused on other things.
We are all different. In the ideal world people who lack some ability will excel in another. When each person puts their skills together as a group a good team is formed.
FairPlay if it’s also your hobby and it keeps your mental health at bay, respect? Ive currently got a Gardiner backpack plus trolley that’s still going strong after 3 years of daily use that cost me under £150. For the money that it’s earned it’s money well spent. For me building my own would just be unpaid work when they are cheap enough to start with. Van mounts on the other hand are a different story as building your own can save you thousands of ££.It's called not getting ripped off. Of the shelve parts. Better quality control. Its stronger.
Out of interest how much does a trolley build cost you in parts and man hours?Thank you @spruce The most rewarding fact is when customers and and other windows cleaner's ask "where did you get your trolley?? " I proudly say I BUILT THAT" and you see their initial look of NO WAY..
The other fact is I know of 14 other trolleys that have been built from my plans and parts list, oh plus an additional 8 that I built and sold

Way under £200 ? now at a total build time of 10 hoursOut of interest how much does a trolley build cost you in parts and man hours?
