Hi guys,
Got a bit of a problem with my RO that has actually gone on since I first bought it but now I run my RO straight through my DI and then into an IBC holding tank which I have installed a float valve on to cut off the RO supply when it's full.
The problem is that when the float valve disengages and the water supply turns back on again, the RO water comes out at really high TDS for about a minute and then slowly goes back down to normal (10 TDS) and then it's fine from then on until the float valve kicks in again.
This means that for about a minute when the water kicks in the RO is producing about 200+tds that progressively goes down but during that minute the high tds water goes straight through the DI and then into the tank therefore killing the resin much quicker compared to if it stayed at 10 tds.
It never used to be a problem as I used to fill the van tank with RO water and then polish it off on the go meaning I could just run the RO for a minute on the floor until the TDS went down and then fill up.
But now I've built a static system in my shed so I can fill the van with pure, but this problem means my 25 litre DI vessel has crept up to 2 TDS in a matter of months which should last a lot longer if the RO water always came out at 10.
What can be done to prevent this temporary high tds issue?
I do flush the system almost every time I use it for about 3 minutes. And I don't want the solution to be that I have to disconnect the RO from the DI EVERY time I want to fill up to wait for the tds to go down.
Any help would be greatly appreciated as it's starting to do my nut in!
