A few years back, I installed a Saniflo pump to service a basement toilet + shower. Putting it in was a lot of fun, but I've always been worried about having it break. So every once in a while I try to descale the inside.
But what product to use?
In some countries, you can buy a branded product to clean these units. It's not sold in New Zealand where I live. When I asked the local rep, he said they've had good results with hydrochloric acid (well diluted). I've done this a few times, then noticed on a brochure that hydrochloric acid is the one thing they recommend you don't use as it can eat into the seals.
Would anyone happen to know what's in the official product, or be able to recommend a product that's an effective descaler but won't damage the seals (if that even exists)?
