Who supplies them - I'm sure I saw them somewhere a couple of years back?

Vyair.

Thank you - I couldn't find that on their site!

Might be worth considering the cost of replacement membranes:

£130+ for the pair. 

[Dave Willis]

yer initially it looks very good value for money except a standard 450gpd is only about £180 elsewhere. might just stick new membranes in the one I've got again.

I cannot work out if that system comes with the two booster pumps or not as the 'what's in the box' isn't clear.

Any ideas?

Yes it does Ross.
Both pumps are fitted and ready to go.

Cheers Andy.

That seems quite a good price.

I've a Merlin and I'm finding that the last two sets of filters (ro + carbon) seem to be incredibly slow with the same water pressure as previously and the wastage incredibly high.

I might buy the Vyair and try that.

John Hewitt does a 400 gpd or 600 gpd RO.

But Out of Stock.

[rosskesava]

That's decided then.

When the John Hewitt 600gpd is in stock, I'll buy that.

I've just checked the tds from my Merlin and it's 54. The filters are less than 2 weeks old and running at 1.2 bar and I make about 150 - 200 ltrs a day.

They used to last me about 8 to 10 months before the tds went above about 30.
