Leaking RO unit.

[paul spark]

I recently got called to a home patient with a leaking WRO300C. I returned the leaking unit to our workshop for inspection, this is what I found.  Never seen anything like this before.

2014 RO unit, this is its first fault. Its been at the same address since commissioning, it has 1500 hrs on the clock.

It needs the following

1 Shell tube for RO-module W514003001
1 End plug out complete W515009001
4 Bracket kit for end plug W506012001
1 RO-element K10640001

Quite a spectacular fail!, has anybody seen anything similar?

Wow, never seen that before, although we don't have many of the C units. Has the membrane housing split and the bolts sheared off? how was the membrane affected?
I've had a push fit connector on the reject line shear off the end plate, but nothing like that.

Wowzers!

Could it have been badly constructed from the factory and its just been a ticking time bomb?

[paul spark]

I suspect the bolts weren't tight from the factory.   I've already replaced one housing that had hair line cracks around the bolt holes - causing a slight leak.

I've emailed [e-mail] for prices - not had a reply.

I emailed about technical training - not had a reply there either.

Thanks for that.
Repaired RO using existing membrane, output flow was very low.
flushed with RO clean 2 and RO clean 5, output flow shot up to 2.6L/ min
adjusted flow back down to 1.2L/min and all is good.
Checked disinfection log, patient had not disinfected/descaled RO ever.

[Chris Bates]

We had a patient who  didn't disinfect or descale for about 2 years.
Very hard water and no softener for the first year, then never changed the salt on their softener.
This is with a centurion which don't like hard water at all.
Never had a single problem with the RO  - weird !!
