Flushing action in our 2 toilets is beginning to slow, sometimes requiring a 2nd flush.
I have checked the rim holes, and they are open.
Last May when I had a no-flush situation, I used a responder's suggestion regarding muriatic acid, and it was very successful.
I think another rim cleaning may be needed. Are there less drastic methods than MA that I can use to do this?
The siphon seems to be clear and open.
All suggestions are appreciated.
