The solid state circuit board which forms part of the flow switch we launched in 2014 has never failed to my knowledge, so when a failure was reported in 2020 in Measham, Leicestershire, only 12 months after installation, I decided to visit our customer to find out why.
How could a solid state circuit board have failed, or why did the flow switch jam?
Sadly, I find that some customers do not read the instructions sent with our pumps, but the worst offenders are plumbers who do not understand how a compression joint works (find out more about this here).
To stop a compression joint working you need to put lots of PTFE tape around the screw threads as this stops the compression joint compressing the olives properly.
Next, you need to put lots of plumbers mate inside the pump to stop it leaking. Any excessive paste can block the filter, which reduces the efficiency of the pump, and finally, the paste mobilised by hot water finds its way into the flow switch and jams the flow switch.
We are always sympathetic to customers and in this case, we supplied a replacement pump, but I hope the plumber agreed to waive his fitting charge!
