House water pump/supply system questions

[NoDisplayName]

****UPDATE****

 

Spent a fruitful evening on YouTube and have the matter sorted for the time being.  Learned that the 2-liter accumulator (Hey, there's a new word!) can lose pressure over time.

 

 

Videos from Myanmar and Indonesia show how to install a car-tire inflation valve to the end cap, but local models already have the re-pressuriser valve included.

 

This morning removed and cleaned the accumulator.  Tested (Stick a chopstick in it!) and found the diaphram was up against the top cap.  It was serving no useful purpose at all.  Used the bicycle floor pump to repressurize to 1 bar, and reinstalled.

 

Seems to be working properly now.  The ticking noise that I (cityboy with city tap water) thought was the pump pumping, was actually the pump switching on and off.  Now maintaining pressure in the accumulator, pump switches on and hums, then switches off.  And the water-hammer banging has ceased.

 

We'll keep this one until the fall, then replace with a Hitachi or Mitsubishi constant pressure model without adding a separate pressure tank.  This one will go out by the spare water tank and will set up piping to liquidate the fruit trees.

 

If the accumulator leaks pressure, we can easily replace for around 200 baht.
