Morning folks. Simple problem but google is no help. I've got a 1.5 year old Coleman inflatable lay z spa and the heater pump is very noisy. I disassembled the 'egg' and pulled the pump out. The impeller body that sits on the shaft in the motor housing is cracked and full of water. Coleman/Bestway is no help whatsoever and the only 'spare part' I can purchase is a new egg. Seems excessive and expensive for what is basically a $10 impeller part. However google is proving useless as Bestway has these things on lockdown and i'm getting nowhere trying to source the pump or impeller. please anybody have any bright ideas?
