Hello!

 

I am actually living in a villa and I am having an issue with a noisy water pump. The water pump is located outside and every 2-3 minutes it activated itself automatically, even if nobody is using water. When it's activated, the pump is making a loud high-pitch noise that last 5-6 seconds. It's very annoying if we want to relax outside, swim in the pool or even just letting the door open. I can also hear it when I want to go sleep, so it's disturbing my sleep. I don't understand why to pump is activated automatically without anyone using the water.

 

My girlfriend told me that it's like that everywhere in Thailand, but I have my doubts.

 

Did you ever been confronted to a noisy water pump problem? Is there any quick-fix to that?

 

Thank you!

Could have a leak, dodgy check valve, dodgy/dirty pressure switch, dodgy diaphragm so air pressure is lost etc. Leak could be anything from pipes to toilet cistern continually draining -- turn off all taps and see if the meter spins. If renting, get them to look at it. Noise could be worn bearing. For quick fix, isolate the thing at night at least. If it was anything like ours, the mains pressure was enough to run the house anyway.

You mean that I could actually completely turning it off at night?

It depends upon how the house is plumbed. You could try turning off the power to the pump and see if you still get water (flush the loo a couple of times to empty the pressure tank).

 

Of course the proper fix is to find the leak.

 

Replacing the pump with a better quality unit should reduce the noise (our Grundfos is so quiet you have to listen carefully to see if it's actually running) but of course that's not a cheap option. 

You could also have a neighbour getting “free” water...

That can’t be the problem. The cause is a continuous small leak. It could be in the pipes. It could be a toilet tank valve , it could be a tap that is dripping. It is almost certainly  less than 1 litre per hour

True as many people do not fix the problems.....  

 

Live in a small Village, had house built in 2003, moved in 2004,  since have had the problem many times,  managed to fix every time, + about 3 years ago took the pump out and took to the Farm machine shop for a full  service.. about 12 years ago found/ hear a leak under the downstair bathroom, re did all the plumbing to the outside,  and sealed off the old pipes 

 

Just started doing it again, close inspection = 2 of my 5 outside taps are dripping when off + a small drip from the joint from the pump..  

 

Most of the houses in the Village have had repairmen in a few times,  next house up = one time had to have part of the garage dug up as a joint had a leek, the next 2 houses down have had repairs done about every 2 years

 

so yes it is ongoing............  If you take a tap to bits often find fine sand is not making it seal = many times all inside taps = clean + new rubbers......  last year took most of the water out of the storage tank....  Yes lots of sand in bottom  + was the reason the tap float was not full switching off.

It is also possible that dirt and grit have worn the vanes in the pump. That would explain the noise and a loss of pressure.

Turn it off when you're not using the water is the quickest fix.

How do you know that the neighbour doesn’t have a leak ?
