RO membrane and housing sizes

[AnMadraRua]

I've just bought 2 new membranes for my filterplus system but they're narrower than the ones they're replacing and they can rattle around in the housing and they're not producing any water. Will I need new housings for the new membranes?

You've bought the wrong membranes for your housings.

I'll just buy two new housings and connect them up so I can get back to producing water.

That's a solution. However, if the membranes are smaller then they won't be producing as much as the original which could become an issue.

I'm not using that much at the moment, about 150 litres and the 2 new membranes are 150gpd so I should have enough capacity.

So you needed to order 300gpd membranes x 2 = 600gpd.

You will get half the production.

Now you will have to find out what size pipe your Filterplus r/o has and order the housing that has the correct size. I don't know but I would imagine a 600gpd will have a 3/8" piping where most housings for 150gpd will be 1/4" for 1/4" tubing.

So you will have to order a 3/8" to 1/4" reducer, 1/4" tubing, 1/4" T pieces and a 1/4" flush valve.
