Richard I agree, my exact thoughts. 
How many coaches are running around with faulty pressure switches?

I will install a ball valve between the pressure switch and the block it is mounted to. When the system is serviced, close the valve to protect the switch. 

I’d also like to add a bleed valve to the accumulator connection at the bottle. 
I’d like to add a bleed valve for servicing the system to the outermost hydraulic port on the rear centering cylinder (anchored side). 

I believe these would be beneficial modifications to the existing system.
