You need to get a pump to further increase the flow.

As for additional contaminants, Disruptor cartridge removes most of these that could be possibly removed by activated carbon.

Limiting factor is always carbon block, not pre-filter. Easier to install the pump if you really want the flow to be honest.

You can't backwash pre-filter, it will damage it. Anything pleated polyester cannot be backwashed, unless it is specifically designed for backwash.

You can just remove all the cartridges and see how is the flow. My guess, even with all cartridges removed, your flow will not be significantly better. Stage 1-2 and pre filter also have almost 0 impact on flow (when clean)

WoW.. All it takes was just a word "Fake" and hell break loose. 🤣😃😂

Yeah, that was the first time washing the filter cartridges since new. Quite disappointed with the labelling. Luckily it was on the outside. 😂
Yes, the water filter is genuine with the relevant certification provided.

Any sifu can advise ?
How to achieve a better and or a longer lasting flow rate with out using an electric pump?

After washing the filter cartridges the flow are back to normal ~1,650L/min compare to before washing ~1,470L/min, but i can't be washing the filter every 6 weeks.
Of course i can prolong the washing to 3-4 months, by that time i presume the flow will drop quite significantly and it will be a longer waiting time to fill up the water for rinsing/soaking fruits and vege.
Thanks

I measured mine for you now, but my cartridges (stage 1-2) will be 2 years old in May, stage 2 will be 1 year in May. Also I have 2in1 faucet which has lower diameter.

Tap - 6.3L/min
Filter - 3.3L/min

This is with old cartridges and I really turned down the inlet valve , otherwise water is splashed all over the place (very low sink). I am suspecting that your issue is not a flow, as far as I know your flow is super high, over 9L/min. Your issue is the pressure. You need some pressure to push water through cartridges faster, there is no way around it . Any reason why you do not want a pump? In your case, it would be perfect. Just even if you do get a pump, do not push over 6L/min through these cartridges

Mine is actually 4 stages, since I have 1 filter in test, so it is carbon+Disruptor.

Can you do a very simple test? Disconnect the tube right after the inlet valve and measure the flow there, so meaning after the valve, but before any filters. Your tube is 3/8", so it should be relatively high. You will see that maybe inlet valve is broken, who knows.

My pressure here is roughly 52psi, at night it is higher at 55. But I have seen over 2L/min with pressure around 35-40 as well. When it drops below 30, then there are some troubles, but with 30psi you usually can't even take a shower

We are working this MCO period. We can also do installations IF your condo management allows

To add to the previous post, just now checking Disruptor which is about 14 months old, cleaning done 3 months ago:

Tap water flow 12s for 1L = 5L/min (considered rather slow actually)
Filtered water flow: 35s for 1L = 1.7L/min

So at bare minimum and with brand new cartridges, if your tap flow is 8L/min, you should easily have 2L/min from the filter (in reality it should be 3.5-4, 2 is really bare minimum).

So it is either total lack of pressure or something somewhere blocking the flow.

Oh, I see what you mean. Your water seems to be quite dirty. Not the worst I've seen, but there is definitely lots of iron, therefore rust on the cartridges. Any cartridges get less flow as they get dirty, that is normal. However, there are 2 factors here:

1) When you have a flow of say 4L/min and drop to 3.5L/min it is hardly noticeable. Of course when you have 1.7 and then drop to say 1.2, this is more significant. In other words, you are already on a low flow and now it is getting lower, it's frustrating, even though the drop is the same in terms of ml/min

2) Unfortunately the drop in flow is not linear. I know you think of it in terms of %, saying if 4L dropped to 3.6L, it is 10% loss, so 1.7 should also drop 10% to 1.53. It should be like that in theory, but in real life it is not. Losses at lower flow/pressure are much higher.

What is the regular tap flow nowadays, still 8L/min? I would suggest to try and troubleshoot it once again. The simplest way I can think of is to remove ALL the cartridges and checking the flow. If the issue is low pressure in your system, then without cartridges you see significantly better flow. If, however, there is only slight improvement, then the problem is with some connectors somewhere. I am wondering if there could be some teflon tape partially blocking some fitting... Must be something very simple that we can't see. I understand that you are happy with 1.7 flow and want to keep it this way. But, if I could come up with analogy, it is like if we have a hole in the petrol tank, but trying to keep fuel consumption low by tuning the engine. Hope we can find a solution together!

1) Harmsco makes one of the best  pleated polyester filter out there. If you need more surface area you will have to go 10"BB, but you will experience more pressure drop with it most probably. And that will not be cheap. Other option is not to use 1 micron, but rather choose 5-10 micron.

2) It will help, but it will not reduce degradation by 50%, maybe 20-30, hard to tell.

But with 6-8L/min of tap flow, you should still have ~2L/min flow from the filter. Let's see what the test without cartridges shows.

Dear all, we are currently out of stock. We had a flooding in our warehouse, and while all cartridges are vacuum wrapped, as some may know, stage 2 from Disruptor is not. We have 2 boxes of damaged cartridges that we now must dispose. Ordered new ones, but they are coming in mid-end June. Really sorry about that, I know some of you were counting on installation in the next few weeks.

P.S. we had 2 units saved, but these were ready for installation and were reserved already. I will update in this thread as soon as stage 2 becomes available.

Problem is there is no better ones. There is not 1 with better flow.
Just today I was able to do the measurements. Time to fill 1L of water, 2in1 faucet, cartridges over 1 year old. Please ignore my last measurements, they were faulty, since I partially closed the inlet valve (carbon in old, I wanted slower flow through them) and I forgot about it.

Tap water: 12s/L
Disruptor: 18s/L
Disruptor without cartridges:16s/L

Which translates to:
Tap water: 5L/min
Disruptor: 3.3L/min
Disruptor without cartridges: 3.75L/min
As you can see, cartridges, even when old, contribute to minor drop in flow, 10%

There must be something wrong with your setup. Maybe the faucet is not installed properly, or something else. Unfortunately, since our installer did not do the installation, I can't really say what it is from distance. There must be something obvious, since drop is huge. Tube bent somewhere?

At this point the easiest would be probably to get our technician to take a look at it and isolate the problem or at least come up with a solution. Since he is also our assembler, he will inspect Disruptor itself. If the issue is with the filter itself and not the connection (let's say assembled wrongly, even though every system is tested once assembled), the visit will be free of charge. Would that work for you?

Thanks for your kind words. You did not damage the cartridges, but if you open it every 6 weeks, I can't say what will happen with o-rings, but should be ok probably.

Anyway, I recommend you continue to troubleshoot it. Next time when you open it, please send me a photo of the head from the inside. Also, try to connect faucet to water inlet directly, bypassing the disruptor. How confident are you that faucet is not an issue (just a question, not trying to say you did not connect it well).

Some of you are now getting grey stage 2 instead of old red one. It is a free upgrade for us by the supplier that we pass to you. Basically the supplier approached us and said that we are the inly ones using the cartridge without the carbon layer but with the silver impregnation. So they suggested that we switch to the configuration with additional carbon layer for the same price, which we gladly accepted.  Additional layer should help with taste/odor and help the main carbon too. I would not call it V2/V3 upgrade,  since it is not that significant, but nevertheless, it makes the product better.
