Hi guys,

I just got my key for a sub-sales 10year old DSL house. Renovation will start after CNY.

The water pressure is "OK" for now. But has been planning to 'upgrade' my master room toilet with bathtub and normal instant heater. Here are some of my questions, hope can get some advice.

1. The house is vacant currently, the meter reader is the same since the 1st time i walk in until today, (more than 2 weeks), so do this means that the house no pipe leak?

2. The risk for installing Grundfos pump, is possible that the original pipe cannot take the pressure and cause water leak on the join?

3. Do Grundfos pump required yearly maintenance?

Thanks
