Hi Experts
I switched off my mains off last time and I believed it caused air block to my water pump. Furthermore, I left it as it was for too long and it broken my "Moonsoon N3.0 bar TWIN" pump.
apparently the storage tank was too small and can create air blocks from time to time. I was wondering if you could advise a good pump if something is better on the market.
Also I'd like to know if it is economical to repair the existing pump.
The symptoms I noticed are
1. not cold and hot water from shower head (has water elsewhere in the house)
2. removed shower unit to check if any water pumped up. We found only tiny small amount of water come out from pipes.
3. tried to add more pressure to the shower pump valve and didn't work
