It's has been app 8 weeks after the 1st cleaning of the prefilter and the flow are getting slower ~1,200L/min compare when it's new ~1,650L/min. It's about 25% lower flow rate for ~14weeks usage.
After cleaning the both prefilter (5m & 1m) and the disruptor, the flow are weaker (~1.33L/min) compare to the first cleaning.
I foresee that in the following 3 or 4 months the flow will be going down again.
Please advise on improving the flow.Thanks

Hi, we have already discussed it couple of times. Issue is not with a filter, since you had exact same issue with Aquasana. Your water tap flow is superb at 8L/min, yet your flow with brand new cartridges is extremely low of less than 2L/min. There is either absolutely no pressure in your system (flow does not equal pressure), or there is some issue with components like inlet valve, tubes or other leftovers of previous system You can either try to troubleshoot yourself by checking which component causes it or we can send a technician (he will charge for the visit though, since you did DIY installation). However, if the issue is with complete lack of pressure, then only solution is the pump. However, it is highly unlikely that your pressure is so low. Disruptor is able to easily give 2L+ in places with 30psi. Below 30psi it is difficult to even take a shower.

Also, please note you are trying to measure ml, that can vary from day, time etc. The magnitude of the problem is not that it went from 1.6 to 1.3, this is arbitrary. The real issue is that it should not be less than 2L/min in the first place.

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.

Thanks for your advise.
Good to know that even with an 14months old Disruptor still be able to have ~1.70L/min even with a slower flow of 5L/min.

Yes, i've thought about the flow/pressure might vary form different time/day.
Maybe i've a lower pressure but now let just put the thought behind.

First let me be specific on the matter.
I'm not asking for a super flow of 3, 4 or any higher rate of flow.
I'm quite happy with the flow of ~1.70L/min, of course if it can be better the merrier.

What i would like to achieve is that the flow rate will still be acceptable tolerance of 10 -15% at the end of life. By your opinion, can it be possible?
Even with frequent washing ~7weeks once, the flow are getting lower.

Hope you can help/advise on how to achieve a constant flow with lesser washing at the end of life.

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!

As i'm in a old housing area(>15years) the piping are mostly clogged with a poor water flow and dirty water, so can't expect much of a high pressure/flow.
The flow rate might fluctuate from ~6.5- 8L/min, definitely not more than 8L/min.

Will try to test the flow with out all the cartridges just to measure the flow rate. That will be another weeks as i've just clean it last week.

1) Can you supply a better 1m pre-filter with more  surface media? As more surface media will prolong the clogging and in return a better flow rate in a longer time.
2) Can a parallel pre-filter helps with the clogging and prolong the flow rate?

If this two methods help, it will definitely slow down the degradation of flow by ~50%.

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.

Today flow rate direct from 3/8 hose before the pre-filter ~6.8L/min.
Flow after the 1st pre-filter housing only are ~2.05L@20secs = ~6.15L/min
Flow with 4nos of housing only are ~2.15L@38secs. So it's ~3.40L/min.

Flow with 2 pre-filter instal (5m &1m) and 2 housing only(Disrp & Carbon) ~2.00L@38secs = ~3.16L/min
Flow with 3nos cartridges instal but w/o carbon ~2.05L/min
After re cleaning the pre-filter and Disruptor the flow with all filter cartridges inside the housing  are ~1.45L/min.

Conclusion - With out any cartridges on all 4nos of housing the flow rate drop from 6.8L/min to 3.4L/min. That's a HUGE drop.
2 pre-filter cartridges, just drop ~0.24L.
Disruptor drop another 1.1L and Carbon drop another 0.6L

Mind to test yours w/o cartridges?

Help me.

Yes, will test it today or tomorrow. We had a little incident here at the warehouse, it got flooded, so was really busy in the past few days.

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.

Goosh,,, What a big mess and unfortunate event.
Hope you be up and running asap.

Yes, no doubt that Harmsco and others US manufacturer has a good pleated filter. Do you intend to bring in a better/more media surface for 2.5 X 10 X 1M?
As per my test, the pre-filter flow drop ~10%.
If by using a better/more surface media, it will by most drop another ~5 - 10%. In return it will has an extra ~ 50% filtration capacity in which will help to slow down the degradation of flow.
Couple with parallel pre-filter consist of 2nos 1micron(more surface media), i think it would help to improve my water flow rate. Even a 10% - 20% would be a big help.
That's my logic. Workable or not need your expert opinion.

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?

Thank you for your kind offer of inspecting the filter system. Appreciate your offer and outstanding customer service.
Will take a rain check on this, as time are not right.
Our housing area are still enforcing no visitor regulation on this RMCO period.

Anyway, I've just Re-clean again the pre-filter and disruptor last evening.
This time i jet spray with my thumb against the tap outlet pipe instead of running the water like your video.
Now, viola,, it ~1.68L/min. Yeah,,  i know it's still not as high as expected but still it's manageable.
Hope i do not damage the cartridges. 😂
This will last me for another 6 - 8 weeks and the cycle repeat again.

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).

By the way, these labels are not acceptable in this condition. As soon as we get new tested batch, I will send you a new set of labels, should not be like that.

Do i need to apply any lube to the o-ring and treads since i need to service it regularly.

Good advise, will check on the faucet on the next available time. Even thou the connection/installation of the faucet seems simple, need to rule out every possible problems.

What do you mean by "bypassing the disruptor"?
1) Do i need to disassemble the 3nos of housing ? For this method, i do not have the individual connections to install back individually.
2) Just take out the Disruptor and Carbon's cartridges from the housing to check on the flow on the faucet.

As i've re-cleaned the filter couple of times, i'll not need the label. Simple as ABC. Anyway, thanks for the offer.

Hi can know is the stock available?

Hi, filters are available, we received cartridges on Saturday.

Hi hestati, can you pm me whats the difference between fresca disruptor and aquaphor crystal eco?
