DIY descale pump :)

[gassafe]

I'm not sure use what other guys use to descale stuff but I made this awhile ago for descaling heat exchangers in situ etc & decided today to use it at home as my electric shower has been getting worse & worse & only ran scalding hot!! Used it today & the shower is like brand new again through all the temperature settings! I was thinking of just binning it & buying a new shower lol!

Interested in where you found the White and Black tanks and what the pump is please.

I just bought a miniature waste bin (similar to the food waste ones some people have) & put a JG 15mm tank connector in the bottom, then it's just a 15/60 from an old boiler to a washing machine hose! It's all housed in a big styrofoam type container which is handy to keep it all together in, so pretty cheap to make!

What are you pushing through the pump to descale the heat exchanger regards Tunpin

I had some descale chemicals in the shed. I also used some Kilrock that is used to descale a kettle, I added hot water & kept the level just above the tapping in the tank to keep the concentration as strong as possible.

How long did you circulate it for?

How long did you circulate it for?

Just left it for 20 minutes, it had stopped foaming in the tank by then so all good I guess!

i made one up years ago for descaling saunier duval water jackets much the same as yours but i used a plastic jerry can/ camping water container the old descaling cyrystals used to jam the pump if i forgot to flush it through properly but in those days it was all conventional to combi swaps so had a great supply of second hand pumps
