Hi it's time that I replaced my 4040 ro. Does anyone out there know of a decent make ? I have about 5bar of pressure so I'm not sure if that puts me needing a low pressure Ro? any advise would be greatly appreciated

If you do a search on the forum such as "4040 membrane" or just "4040" you will find an answer to your question, although I'm not 100% sure what you are asking in your post.

I think you need an HF5:

i'd go for an axeon hf5 membrane pal with that sort of pressure, dont try saving money on something slightly cheaper, the hf5 you wont go wrong

With that pressure the original poster is getting provided they’re not bothering with a pump they’re probably best sticking to a hf5 membrane rather than a cheaper hf4 do you not agree?
