Thanks for the info. That is the very reason I am holding back my purchase for water purifier. Yes, housing pipes are exposed to direct sunlight and the water flow through the kitchen and bathrooms can get really hot.
Other reason why I was considering LG is because it gives me the flexibility to self service the filter but having the abnormal hot water coming in is just a drawback now. Do you have any alternative towards this other than the mini tank?
I think can test the temperature on a sunny day then only decide, if temperature is only 40°C, LG filters can cater, but probably ur water will taste a bit warm if u don't mind
But if exceeded 45°C, can consider few options:
1. As Dayalan mentioned, off the purifier valve then let the water runs cool first before using, a bit troublesome but doesn't cost money
2. Insulate the outdoor pipes, cost money
3. Water tank to cool off water, probably cost more money than insulation, but can be useful during water disruption too
4. Heat exchanger, just googled there are things like this

, but probably the most expensive option and also consume electricity
But anyway, test first then only decide, maybe ur water only 40°C then u can forget bout all the above
