alexpoker Posted September 3, 2020 Share Posted September 3, 2020 hi all, Looking for some guidance. I intend to get a plumber to help me with this but Id like to advice on what needs to be done so I know if the plumber is legit or not. Anyway we have quite low water pressure coming to the bathroom. Faucet and shower. Shower is a bit better but faucet is terrible. Its a 7th floor unit and we even installed a pump from the main pipe into the water meter, which helped for a couple of weeks but then got really bad again. What needs to be done here to fix this problem once and for all? Its an older 20 years+ building up here in Chiang Mai. We've spent 10k baht on installing pump and some other stuff and now back to square 1. Please advise! Thank you in advance! Link to comment Share on other sites More sharing options...
scubascuba3 Posted September 3, 2020 Share Posted September 3, 2020 Other condos on the floor have the same problem? apparently condos can reduce the pressure of the water from approx 7th floor and down, maybe that's gone wrong Link to comment Share on other sites More sharing options...
alexpoker Posted September 3, 2020 Author Share Posted September 3, 2020 I believe others also have this problem in the building(not verified), but others have installed pumps along the main pipe as well. Link to comment Share on other sites More sharing options...
briley Posted September 3, 2020 Share Posted September 3, 2020 Very hard for an individual owner to do anything. Pressure depends on the height of the tank above your unit, the flow available, ie the size of the pipes and if there are any 'flat' runs or too many bends. It is possible to pressurise the water system or part of the water system. But all of these solutions have to be done by the management as they are outside your unit. Also some people expect higher pressure than others, sometimes depending on the water heater installed. Thai water heaters tend to need a lower pressure (the water flow) to work, imported ones a higher pressure. Seem to remember a low pressure water heater can work with around 4 litre per minutes, some imported ones wanted 11 litres per minute to switch on.

Artisi Posted September 3, 2020 Share Posted September 3, 2020 Is this a new problem or an ongoing problem. Have you checked for any blocked filters in the taps, the heater or shower head? Link to comment Share on other sites More sharing options...

Its been going on since the unit was bought, but nothing much was done about it at first as management wouldnt allow any pump installation before, but this time didnt say anything and even showed us where to do it.

RichCor Posted September 3, 2020 Share Posted September 3, 2020 How is the water being served to the building now? Are you relying on the pressurized mains to feed water to each floor, or do some of the floors rely on rooftop water tanks to provide water availability and pressure? If it was an issue with just a few taps I would think, as you already suggest, a plumber to examine the lines and suggest a solution. But if the issue is building-wide then you might be better off with a building-wide solution, like banking water in storage tanks 'somewhere' during off-demand hours for draw later when the mains water pressure is low.

alexpoker Posted September 3, 2020 Author Share Posted September 3, 2020 Will have to ask. I suspect there are no tanks on the roof. Link to comment Share on other sites More sharing options...

If it worked for a week after installing the pump an replacing the tap then maybe, as has already been suggested, the faucet filter screens are being plugged by hard water deposits or other debris in the line. What happens if you take the faucet screen filter off and open the tap? Link to comment Share on other sites More sharing options...

What happens if you take the faucet screen filter off and open the tap? Hmm I believe the pressure there is normal. ok it makes sense then. So basically I should take off the metal filter thing in the faucet? Link to comment Share on other sites More sharing options...

Without the screen the water will exit the tap at unwanted angles. If removing the aerators helps, clean it as best you can and put it back and see how long until it becomes plugged again.
