One of my granddaughters asked for assistance with one of the two toilets in her home.
Both toilets are of the same model and age and of course they are connected to the same water supply. Her
toilet was flushing poorly. Upon examination, I noticed there was a thick lime scale in and around the flush
jet and the drain path. The rim jets were all basically clean and clear.
The other toilet, used by her roommate had no scale of any kind.
I used Zep Acidic toilet cleaner ( http://www.zepcommercial.com/product/Acid-Toilet-Bowl-Cleaner which is a 5
- 10% HCL solution ), letting it sit for an hour or so. The scale softened quite a bit and I was able to
scrape away big pieces but not all of it, even after applying the HCL solution twice.
The toilet is flushing much better than it was previously, but the scale is still present. My next step is to
use some Muriatic acid, which is HCL @ 35%, in the hope this will chew away the rest of the scale. I will
probably dilute the HCL by 50% to begin with.
My quandary is accounting for the difference between the two toilets. My granddaughter is big on saving the
planet, so, if there is only urine in the bowl, she will not flush. Combining that with her habit of taking
lots dietary supplements, I am hypothesizing that many of the minerals contained in the expensive urine is
leaching out and accumulating in the bowl.
I have tried to explain to her the supplement industry is a giant scam and have even provided her with
evidence, but, well, she is a woman and that falls on deaf ears. At least she has compromised and agreed to
flush after each use.
Has anyone here encountered such a heavy scale situation previously? If so, how have you dealt with it?
