Find a mistake


New member
Dear members,
I have finished my first ever loop and I have made some mistakes in the design / execution.
I think I recognize most of them, but I would be very grateful if more experienced builders would
have a look at my sweet construction and point out my mistakes, so I could rebuild it in the correct way.
The biggest mistake cost me a pump (VPP755, it died in three days) Attached photo includes some important
details , please let me know if some other details are important to determine the cause of fail.
Thank you for your time, wish you all everything the best.
