Hi there,

Just recently I replaced my 6 yr old, 1HP Inverter booster pump, to a non-inverter (also 1HP) pump.
Previously the inverter brand name was Ebara (Model Jet EP-1 CDX 90/10), which came with the house. Was replaced because inverter board show up error code, and Ebara Malaysia said it cannot be repaired, need to replace inverter board , which cost almost the price of a new pump.
(And I asked how much a new Non-inverter pump from them - Rm 1.3K including installation. Ouch)
Okay fine, got it replace with this new non-inverter pump (bought from Lazada), which came with the controller (similar to the video posted by "zheilwane") .
Spec wise, the new pump delivers Max 80L per minute and total head 38 Metres.
Old pump spec: Max 100L per minute , total 30 Metres. Still puzzled how come the new one outperform the old girl.
Reason I use back 1HP is because I follow back the original pump horsepower and my house is 2.5 sty , with 6 bathrooms. (but we dont use all)
Long Question Short:
My question is, since the new pump controller comes with preset water pressure from factory at 1.5 Bar vs the old Inverter came preset at 1.1Bar (according to the display unit.) , will it do harm to the piping with the higher water pressure.
I asked the plumber, and he said the controller cant adjust the pressure.
So far there is no water hammering through out the house, except when the washing machine is activated or someone using the back guest bedroom bathroom (which we seldom use anyways) . Well even with the old pump still there was water hammering. But thats just only 2 water pipings out of the entire house.
And no other issues like - Pump intermittent running (when no one is using or when someone is using the water) .
