4040 ro help

[helene84]

We have a 4040 ro system which was working fine until we changed all the filters(carbon, sediment and 4040 membrane) and di resin, since then the flow of pure water being produced is literally a trickle and having left it on over night only filled around 500litres when previously would have filled the 1000 litre tank.

I have double check everything is connected correctly and have double checked that the filters and membrane are in right, water pressure hasn't changed and when a pump was connected it didn't make much difference to the pure flow rate.
Any ideas? Don't really want to have to buy a new system as this one is only around 3 and half years old.

What % waste vs pure are you running?

 

[helene84]

60/40

 

[doug atkinson]

What membrane did you purchase.

 

[helene84]

It was a spectrum membrane brought from baileys wfp systems(same place we brought the ro system)

 

[doug atkinson]

There are two types one is a lower gpd. What product code was on the box if you still have it.

 

[helene84]

Don't have the box but will post some screen shots of the one we brought.

 

[helene84]

This is the one we have

This is the one we have

I think that works out around 100 psi so it’s quite a high pressure membrane

 

[helene84]

We've always used that membrane, it's the one that the system came with and when we last replaced it we used the same one and had no problems until now.
Could it be that the membrane is faulty?

To be honest I have no idea @spruce and @doug atkinson would be the best ones to advise about that. I assume you have given it a thorough flush through for an hours or so ?

 

[helene84]

Yep, when I changed the membrane, filters and di resin I flushed it for about an hour and a half.

 

[doug atkinson]

That membrane is the cheaper one and only does 8350 litres a day rated at 150 PSI. It is no good for normal tap pressure and needs a booster pump that can do up to 150 PSI for optimum results. 347 litres at 150 PSI then you are looking at around 60/80 litres at 40 PSI tap pressure.

As you got the system from Baileys they should be able to sort the problem out for you.

 

[helene84]

But what doesn't make sense to me is that the ro system was working fine until we changed the membrane and it is the same as the one we had previously and never had a problem with or have had to use a booster pump.?
We have tried it with a pump bit makes no difference to the flow rate.

 

[doug atkinson]

What is your pressure gauge reading. Take out your filters and run for 5 minutes and see if that improves, if it does then it’s the filters. If not you need to speak to Baileys they are the supplier.

That’s as much information I can give sorry as some suppliers take offence if I help and find the problem in their systems.

 

[doug atkinson]

Sorry I looked at the wrong information on the specification it’s rated at 100 psi.

 

[helene84]

Have ordered a pressure gauge which should be here tomorrow so will check it when it arrives.
Thanks for you help, it's really appreciated ?

 

[johnny bravo]

have you spoke to baileys or have they ignored you

 

[helene84]

Haven't spoken to baileys yet, going to check pressure and run the system without filters and if it's still the same will contact them.

 

[johnny bravo]

i tried to chat to them via there website never acknowledged at all i wanted some advice but never got back

daqua got back to my queeries straight away . Decent Chap with advice

 

[helene84]

So I've check our water pressure and it's just below 100psi, I've run the system without the filters in but the flow of the pure is still just trickling out. ?
Have contacted Baileys but no reply.
I think we may just have to get another system, has anyone got any suggestions on the best ro system? We use around 1000 litres a day.
