There are some retic service jobs you just can’t explain logically why the install was done the was it was.
I came across one of these this week. The master solenoid had failed, it happens so no biggy there. It was where I found the solenoid to change it out which was interesting.
The Master solenoid was underneath the driveway about 150mm back from the inspection hole. Bit of a tight squeeze, we got it done.
Lucky it was just the diaphragm and coil that had failed. As it would have unfortunately meant cutting up the driveway to repair this leak.
