Title: Di vessel pressure?
Post by: David Beecroft on September 22, 2016, 05:03:06 pm

Hi Folks, I'm one of those fortunate to live in a soft water area, hence I don't require an RO system just a Di vessel to polish it off.
I have a Resin saver Vessel which has a label on it saying "working pressure, 8 bar, 116 psi".
My water pressure gauge reads as 21psi when flowing and 63psi when dead ended.
The questions are; 1. do I need 116psi before the vessel will work properly and 2. If so how do I get the pressure that high.
Any comments would be appreciated.

David.

No, it's most probably max pressure, I've had one explode before   :o

Thanks Soupy, it does say working pressure?
Anyway the real question I suppose is, does the di vessel work better at high or low pressure?

I'm not an expert but an educated guess would be, it makes no difference.

pressure is not important as long as its not over the limit for the vessel but a slow flow is more efficient than fast flow as it allows more contact time with the resin .

Thanks for the input Guys, I'm still not convinced though. Di vessels are essentially pressure vessels.
Anybody else got any technical info that adds to the picture.

what do you need convincing of?

thousands of window cleaners use them day in day out .........or is this a wind up?

Test the water at 21psi if it's 000ppm what other evidence would you need?

If it was a pressure vessel then it would have a safety valve

Just copied this from Cleaning warehouse website; Just filled your DI vessel/ Pressure vessel with Tulsion 115 and watch yor water purify to 000TDS

Notice the reference to  Di Vessel/pressure Vessel. ???

A di vessel has to be able to withstand pressure- otherwise you could never stop the water flow in-situ. I have been using them over 12 years and the less pressure the better.
