@Guest, details of the water change set up. It’s not fully automated but makes things simple. Better planning would enable the waste to be positioned beneath and behind the tank or hidden better, however I didn’t know exactly the cabinet dimensions, access or position the builders placed things at the time and now although I could hide the waste behind the tank better, it is more practical where it is and you can’t see it in the living room anyway as it’s tucked away in the corner beside the tank.
I basically asked if the builder could put a hot and cold feed to the living room. They agreed and although initially placed them in the wrong place (as in the image below) I got them where I wanted them, behind the tank and hidden. They also put a waste away in which I’d planned, as it is conveniently on the other side of the washing machine wall:
Once finished and moved in I just plumbed in from the existing hot and cold feeds....
I used my existing equipment from the discus tank which was a ‘Bulldog’ thermostatic mixer valve, 3/8” John guest pipe and fittings and a 20” hma filter. The 3/8” pipe and fittings are used to allow sufficient flow rate (up to 7.8 liters per minute) so the boiler kicks in to get the hot water. A 20” hma can take the higher flow rate (plus the filters last longer......and I was doing a lot of big water changes on the discus tank; 2x 300 liter changes a week
😱)
The mixer valve just needs the hot/cold bias adjusting to reach the desired temperature, then it is set and can be left alone.
The hma fully removes chlorine and chloramine so no chemicals needed when water changing. The filters last for 30,000 litres but I tend to just replace annually at a cost of around £40.
I just have excess pipe below the tank with inline valves so when refilling I just pull it out, hook over the glass and open the valve.....
If a cabinet tank or tank with a coloured background were used instead of a rimless braceless minimal set up, you could hard plumb this all and just turn valves, however I didn’t want pipework to be seen.
The drain away is just a simple u bend and pipe which link into the washing machine drain conveniently on the other side of the wall. Not the prettiest solution which as I said could have been hidden under the cabinet, but I can’t really see it where it is in the living room and it is more practical like it is......
Quite simple really but saves an incredible amount of faffing around with hoses and buckets and water conditioners, especially on larger tanks
Cheerio,
