RO Filter Housing Burst

RO Filter Housing Burst

Filter housing burst due to high water inlet water pressure.

  • RO Filter Housing Burst is due to a few factors that cause the water filter housing to burst.
  • What we have found is that the sales people and marketers inform their clients that the filter housing can withstand water pressures of up to 100 kPa or 10 bar.
  • Yes the filter housing can may be withstand that water pressure.
  • If you cater for that high water pressure you have a big surprise waiting for you.
  • What the people do not keep in mind is that it doesn’t matter what the maximum pressure your water filter housing can withstand.
  • It is what is the weakest part or point in the system.
  • That is the most critical point.
  • If that point is low then you must work around the maximum water pressure that part can withstand.
  • Do you agree?

Why does the RO Filter Housing Burst?

  • A client phoned me the other day with a big problem.
  • Her reverse osmosis systems filter housing burst during the night.
  • They were fast asleep and the morning when they woke up the kitchen floor was covered with water.

  • She bought the system from a supplier and they did the installation.
  • The day of the installation the council was busy working on the water supply to the suburb.
  • The service provider’s technician had no problem with that.
  • He installs the reverse osmosis system in hours’ time and left.

How the Reverse Osmosis system worked.

  • The system work as we thought it should work.
  • When we open the faucet, the water was coming out with force and it tasted fantastic.
  • Before she used the faucet she thought by herself that it would take ages to fill the kettle up with water from this small faucet.

What happened the night the RO Filter Housing Burst?RO Filter Housing Burst
  • It was a hot day and they watered the garden.
  • They were tired that night and went to bed early.
  • During the night the filter housing burst spilling water all over the place.


  • Why did it happen?
  • The filter housing burst would have never happened if the technician who did the installation did some testing before he install the system.
  • The water pressure to the house was 800 kPa during the day.
  • He did not test it because the water was cut-off that day.
  • During the night nobody use water and the water pressure increase to about 1100 kPa during the night.
  • The filter housing burst for it could just stand pressure up-to 1000 Kpa.
What could prevent the filter housing from bursting?
  • What the technician must have done was to install a pressure regulator before the system to regulate the pressure in the system.
  • Remember the system is just as strong as the weakest part.
  • If he installed a pressure regulator the filter housing bursting would never have happened.

You always work according to the strength of the weakest part never the strongest part.
