I replaced my Grundfos with this Teral from zheilwane i think 2 years ago. Happy with the recommendation so far. I feel it works just as well as Grundfos without the premier pricing.

My Grundfos died on me on year 3-4, after dismantling, found out it was fuse problem and could have been repaired for around few hundred if DIY.

My Teral works equally well , I have it connected to a power switch where I off it when no one is using. Theres a leak in the house and the motor do get turn on and off every 15 mins if I forget to off the switch.

If fuse, RM 5 only
If relay, RM 25 only
If capacitor, RM 15 only
If pressure switch, RM 20 only

Note : Round up

If DIY. you need search around youtube to study the common water pump troubleshooting and repair. It may takes more than 10 hours. Then, need to find parts from online Shopee, Lazada, Taobao etc.
As for me, i will change brand new one and my faulty dismantled one, i will fix DIY slowly (circuit board, bearings, etc). If fuse, capacitor, pressure switch... it's on the spot, no need to buy new one. Water pump is old technology and Chinese branded one will do fine, no need expensive Grundos.

Dear All i would like to ask that water pump have buffer tank. The water pump i purchase is normal without a small water buffer tank attach on top of it. My supplier advice me to add another RM150 to attach a small 8 Liter small water buffer tank to attach on it. He claim that this can reduce the pump working frequency (example open water tap wash hand pump won't run) hence less maintenance and longer life span.

May i know what he say it is true? It really a lot benefit to add the water buffer tank and RM150 is fair price for the tank? Thank you

RM150 is too expensive. I am using 4L for corner terrace house.

Get 370w is suffice. Buy Pressure Reducing Valve with meter around RM 25-40 to control pressure. For old house, start with 1.5bar. Maximum 2.2 bar for old house.

From a DIY with experience in installing, modify piping, service pump (rewinding coil, change m.seal & bearing), repair PS...
