QUOTE(matthewctj @ Feb 23 2012, 12:03 PM) Just bear in mind, PVC pipe joints are not capable to handling internal water pump, which many are installing these days. The pipe isn't the problem, the joints are. why PVC pipe can't handle water pump??? class "E" already have pressure rating of 15 bar, class 6 & 7 > 20 bar  buy those with sirim like "paling"/ "BBB" NOT those "www" found in hardware shop, u'll never face any joint problem for pvc piping.
Added on February 23, 2012, 12:36 pmto me, i've experiencing Lots of ABS fitting leaking, esp elbow This post has been edited by skng03: Feb 23 2012, 12:36 PM |

QUOTE(stevie8 @ Feb 23 2012, 04:25 PM) If you need a strong pressure cold pipe use ABS for pump in the wall for example. PVC class 7 will reduce volume flow due to its very thick layer. You dont use stainless steel or copper pipe for cold pipe it is very expensive, not only the pipe the joints as well many times over the price of PVC and Abs House no need class 7 lar, pvc class e = pn15; can stand 15 bar. household with pressure booster pump normally 40psi=3bar only |

QUOTE(endau02 @ Feb 24 2012, 06:27 PM) R u sure pn15=15 bar? dunno anything dun talk rubbish, k? r u coming from mars  here on earth PN15 have pressure rating=15 bar. 
sourcewhen i said pn15 can stand for 15 bar doesn't mean that u can constantly pressure it @ 15 bar. normal working pressure will be 15bar/2 = max 7.5bar (normal practice). BTW, earth is too dangerous for mars ppl, go back to mars lar  |

[attachmentid=2702300] no doubt the filter casing is cheap, but the 5 micron filter cartridge sold at jusco cost rm12/pc, and here in kl i need to change it every two week esle will face low pressure in the house, not really cheap in long run |

QUOTE(stevie8 @ Feb 24 2012, 10:07 PM) For RM12 I can get 4 pcs 5 microns in Jalan Pasar, Tesco or Giant and pasar malam. You could have bought from a shop in jusco? who specialised in water filter. those people sell in small quantity and also buy in small quantity of course have to mark up high. You can buy from me if you want to half price rm6 a pc. I'll buy from tesco and re-sell you okie? Didn't I show you the pix how to overcome low pressure? Look and study the pix ok? I tried those cheap 5micron cartridge from hardware shop, it useless lar. u try to get one inside jusco, not small shop outside jusco. Brand ue-tec if i remember correctly then u compare the quality:) Running 3 filter in parallel is a good solution but not quite suitable for condo/apartment lar. And i use ss rocket type filter now since i move to my current house, no need the hassle to change the cartridge This post has been edited by skng03: Feb 26 2012, 02:59 AM |

QUOTE(Optiplex330 @ Jun 28 2012, 01:36 PM) So what color is ABS? And what color is PVC, grey, right? Abs = blue color, pvc = grey color. Both pipe (with sirim approved) almost same price, abs fitting price higher. THose pvc sold in hardware shop without sirim much cheaper but lower quality. Abs alto harder, but easy to break/ crack @ T joints n bend. Previously, abs is the only approved cold water pipe for internal piping by syabas, now pvc r approved due to the above… |
