Hi, My new house 2 half storey semi d c/w solar from developer.
1bathroom lvl 2 3 bathroom lvl 1 1 bathroom lvl g All running water from tangki above lvl 2. Most of my friend told me solar will have pump but i checked mine is without. So thinking to install a grundfos pump for 2 rainshower n 2 normal shower. How many HPs should i install? And direct water pressure should be around 2-3bar .should i also install a pump outside ? |

QUOTE(kengyan @ Nov 20 2016, 02:10 PM) Have so much money buy a big house, what is that spending another some for a pump? Haha good one. I think all will be using from tangki instead of direct. Just need info of how many HPs to use as i heard too high HPs will cause hose to crack n can't last long.Keep the joke aside, considering the elevation, I'm sure your level 2 bathroom sure will have low water pressure problem. If want maintenance free higher pressure water supply, you can use direct piping from the main(after filter for sure), else install a water pump just for bathrooms.  |
