I have a pro5 Ionics Reach and wash. My TDS coming from the RO is 008. The water then goes through the DI and is now reading 003.
Before you say that I need to change my DI resin, I already did that. This morning I put fresh resin in and it sat at 000 for the 1st few houses and then by the time I finished I checked it again and it was reading 003

[RO-Sheen]

Come on guys, help me out! any ideas?

[JM123]

?? that doesn't make sense - have you checked it with the handheld??

[RO-Sheen]

HI jonathan

Yep, I tried it with the built in meter and then verified it wit the handheld and both read 003.

If you dont know the answer nobody will!!!

I need to log off now as Girlfriend wants the PC back but I will log in later to see if there has been any ideas.
Thanks in advance

hhmmm, fresh resin this morning - tds creeping up, your water passes from the tank through the pump then to the di doesn't it?

The only thing I can think of right now adrian is that you have somehow managed to get some contaminate into the resin - did you wear sterile gloves when putting the resin in?

this is really odd, I've never heard of resin going off so quickly - do me a favour and just recheck what the tds is of your tank water.

Hi Jonathan

Guilty of not wearing sterile gloves. I did wash my hands first and 'rubbed' the resin in. But this is what I did the last time and it lasted much longer than a few hours!

I went out to recheck the TDS since my last post. Connected the brush up so I had a full flow of water coming out of the van and the inline meter showed 2ppm. Took a sample with the handheld and it showed 4ppm

Just thought of another thing I should mention.............When I was clearing all the old resin out of the vessel I connected it up to my garden tap, took the rubber bung off (that was filling the hole that I drilled in the vessel) and flushed all the old resin out.
When it was all flushed out I 'rocked' the vessel until all of the water was out but there would hae been a few droplets of water left. I then proceeded to refill the vessel with new resin.
This is the same way that I emptied the vessel the last time.

Oh, just thought of something else.... I packed the vessel with new resin until I couldnt get any more in. Could that be the reason? Should I flush a bit out (using DI'd water this time) so there is more room for the water to travel through the vessel?

What make was it, this has been the fourth or fifth problem in the couple of weeks with resin. The window cleaner I helped his resin used Rohm, cannot explain why it went so quick. Starting to think maybe a bad batch out there, maybe wrong 

[JM123]

I can't understand it ady - especially as its from the same bag as you have been using - and I think you store it in the garage (cool dark place).

Hmm, I'll see if I can work it out for you.

[RO-Sheen]

Hi DA - Yes it was Rohm and Haas but like JM said I have used this bag befre on another vessel. The last time the vessel lasts me a few months.

Cheers JM, I will go out and work today and keep an eye on TDS with the built in mwete and the handheld. Will report back my findins

Adie

[DASERVICES]

Same happened to the guy I helped it was the last of his bag, very weird why it only lasted just 2 fills then went black.

[RO-Sheen]

Yeah, I just read that post about the black resin. Very odd! Oh well, im going to log off now and go out to work. Like I said on my last post I will report back my TDS results.

[JM123]

well what was the tds reading today?

I'm still baffled.

[RO-Sheen]

TDS was fluctuating between 5 and 2. I pulled the TDS probe out of the 'outlet' pipe to make sure it was clean and there wasnt a bit of cr@p on it. It looked fine but when I plugged it in again it read 'ERR'
tried taking it out again, rotating it, recleaned it but it stayed reading 'ERR' Phoned Ionics and they said this can happen if the battery is low or the probe was taken out and not put back in the same position. Peader from Ionics told me that there should be marks on the probe and the T connector that I need the line them up but I couldn't see them. Tomorrow I will take the DI vessel off and have a good luck.
However, I carried testing with the handheld throughout the day and it was reading between 2 and 5.

When it rains it pours!!!

[JM123]

really strange that is.

I'm sorry ady this one has me confused.  The only thing i can think of is both tds meters are faulty.

[RO-Sheen]

Do you think the fact I really packed the vessel with resin might have something to do with it?
I have the tank for a year now. The last time I spoke to Ionics they said I should clean out the tank yearly with Milton. Could that be the problem? Should I do that?

[JM123]

you see the problem with Ionics systems is that the water is only ro'd before the tank, ro water can harbour algae etc like no other, di water won't let anything grow in it.  I would in all honesty clean the tank out with milton, take some of the resin out of the vessel - more to break up any water channels going through it, HA THATS IT!! because you packed it tightly the water has formed channels in the resin, if the resin is loose the channels break up much more easily, in fact its much harder for them to form, woohoo sorted, take some resin out, shake it all about do the hokey kokey and bobs your uncle maggies your aunt - problem solved

[RO-Sheen]

Great, I will try that tomorrow. Hopefully my TDS will drop. Will let you know how I get on.

As for the milton. This is how I plan to do it............
When my tank is emptied I will pour some Milton (the same ratio as they suggest on the bottle) into my tank. Then fill up the tank by unscrewing the lid on top of the tank with tap water.
When it is filled up to the top I will then empty it by opening the drain at the bottom of the tank.
When it is all drained out, refill it and then empty it thus giving it a good rinse.

Then refill as normal via the vessels to produce RO water.

By doing it this way I will be avoiding any of the Milton to go the RO membrane or carbon/sediment. Im afraid that the Milton may do harm to them. The only problem with that the hoses that link the vessels will not be rinsed with Milton.

What do you think Jonathan?

If this works and we beat the English at Rugby it will be a great ending to the week! 

[JM123]

as you say, just pour the milton in the top opening of the tank, fill the tank with tap water, swirl it round with a brush shaft or something, empty it out through the valve at the bottom of the tank (you my have to take the valve off to do this), refill with tap water, drain it out again, fill with ro water, beat the English (just like we did at Twickenham just after Jonny Wilkinson England won the world cup.
