Do's the Di Vessel have to used in its upright position?

I.e - can you use it laying horizontally?

Thanks  :

Dont quote me on this but....

Looking at the construction of my vessels suggests they need to be in an upright postion to work correctly.

Depending on whether you have the pump before or after the vessels - Water is either pulled or pushed through the vessel at the top end and pushed/pulled through the resin. It is then forced (by water coming in behind it) out of the top and into your tank or heater or pole (or whever you're sending it!).

Lying it on its side would no doubt affect the 'flow' through the resin - could untreated water pass to the 'out tap' side before passing through the resin?

I think they're designed for 'upright use'...otherwise they would make flat vessels and not round vessels (which are unsuitable for lying on their side).

Exactly David.  I thought the same.

However, if you need a DI Vessel, you could get an overpriced Ionics one, which are designed to go on their side.  They have a hozelock fitting at each end.  They are not refillable as standard though, so you need to fork out £90 odd squid when resin needs replacing.

OUCH!! 

Better stick to an upright vessel unless you really have no other option.

I use an ionics filter as my polishing unit in the van (gets anything from 10 tds down to zero), which lays behind the tank out of the way - lasted over a year so far (only 1/5 used).. But the vessel is the way to go for general filtering, which is done before the water gets into the tank.
