G'day folks, Rod from My Water Filter here today, and what we're gonna do is have a quick look at changing the cartridges in the Doulton Ultracarb Twin Benchtop Water Filter with Sediment Protection. Okay, so you'll know that generally I like to put a bit of a mat or something down on the sink, on the work area where we're gonna work and that's just to make it a little quieter, and just give you something to work off there, okay. Here's our two cartridges that have already arrived, and what we've done, is what we like everybody to do when they get a product from My Water Filter, is top open the product as soon as you can. Even if you're not gonna use it straight away, just open it up, and especially ceramic cartridges are vitally important. The quality of the water that you drink is all about this cartridge and the condition it arrives in. So when this cartridge arrives to your home, we want to inspect the ceramic. So what we're doing is we're casting our eyes up and down the cartridge, and we're just having a look and making sure that there's no cracks in it. They do stand out, and you will be able to see if it's cracked. This ones fine, nice ends on it. Two good washers on each end, so we're good to go. We're happy with that, and we can now proceed with installing the water filter cartridge. And here's our Sediment Cartridge. They're quite strong and robust so we'd never expect too much damage in one of those, so we're good to go there too.
So here's the water filter. We've been using it for over 12 months now and we want to change the cartridges. Water is turned off. Water stopped flowing out of it, so what we're gonna do is lay it over on its side to start. We got the housing tool, it's got Close and Open on it and they actually go down over the top of the housing. It's just normal Australian thread, so we're turn it to the right to make it go tight today we're gonna undo it. So were gonna turn it anti-clockwise looking down on the top of the system, okay? Normally if you put these on the seal will break quite easily.
Obviously depends on how tight you tightened it the year before. So just be aware, that you don't have to swing off the cartridge tool and it doesn't have to be super, super tight. Just nipped up nice and tight to seal the rubber on the face. So once we've done loosened those off they will now unspin very easily, okay. We'll start simply here with the cartridge in housing number one, and this is our pre-filter. Our sediment cartridge, okay. We'll take that one out, lay 'em in the sink. Here's our nice, new, light one. Put 'em into place, and the center cores, both ends, there's no up and down on Polyspun Sediment Cartridge, they can go in any way and they just sit inside the housing, and then the housing will do down over the top. Screw him on. Oh. Better turn 'em. We should turn 'em over. There we go, and tighten 'em up, tight as you can by hand, okay.
Then we go there on the second one, now with this one, this is Doulton Ultracarb cartridge. So you've gotta be vitally careful that we don't knock it over, okay. We don't want to drop this cartridge, we treat it like an egg, whether it's new or used. So let's take the old one out there, we've got a new one here. We've already inspected this cartridge and it's all good to go. Now there's only one hole in the end of the Doulton cartridge, okay? So this hole here has gotta go down into the head, alright? The water is gonna penetrate through the side of the cartridge to the center core.
Then we want it to come out of the bottom of the hole, go into the head, flow up, and come out of the spout. If this was an under sick model the cartridge is up the other way, this way up goes up. On the Benchtop, the hole goes down into the head. So get 'em there, just hold 'em into place while you're putting the housing over. We just don't want to knock it over and bang it, all right. So just get 'em there, nice and gentle, screw the housing on. Nip 'em up, tight as we can by hand. Gently lay 'em over on their side. Put the housing tool back over, and just a little bit of a turn to nip it up tight. We gotta get it off next year, so we don't wanna do it too tight, okay. Just nip 'em up. If you put it together and you got a little bit of water leaking out the bottom, tighten it up a bit more, and you're pretty good to go. Just gently, gently like that, okay. Now, once we've got the cartridges in and they're all installed ready to go, now we want to give 'em a flush. Same way that we flushed 'em when they were brand new. The sediment cartridge here in the pre filter, the sediment cartridge here in position one, that cartridge there hasn't got too much in it.
There's no carbon in it or anything like that so there's no need to remove the second cartridge here. If we had a fluoride cartridge, or alkalizer, or some other specialty cartridge in this system then we would remove the second cartridge while we flush the first one. But today, put both cartridges in, pre-filters got nothing in it and we're gonna flush 'em. So, a good five minute flush for both these cartridges. When you first turn the water on, there is carbon inside this Doulton Ultracarb cartridge. So as soon as the water turns on, you're gonna expect to see a lot of dirty, black water comes out, all right. It's only the coconut carbon. It's totally harmless, but it can be quite black at times. So maybe have a bucket here, gather that carbon, it'll only take five or 10 seconds to come out. Tip it on the pot plant, and keep the water flowing. Flow it for five minutes.
Save the water for the plants if you like, but the aim here is to flush the cartridge. Every cartridge needs flushing, doesn't matter where it comes from. Five minutes, give it a good flush, next 12 hours, overnight, the carbon in this cartridge will activate, and that means that the next morning you can just turn it on, and just give it a quick three minute flush, and away you go. You'll be good to go for 12 months then and you'll get good quality, nice drinking water out of your water filter, okay. So simple as it is, quite simple. Dispose of the old cartridges correctly into the waste and you're good to go. Any dramas, anything you need to know, just give us a call. Have a great day.
