My toilet drain is slow, but if plunged it is fine... for a touch while? I've had this toilet installed for going on for a year...

I've had this toilet installed for going on for a year and a half and it's great - never clogged once. in a minute it's having issues.

If I try to flush the toilet it will feat like it's clogged, but after just about 20 seconds will draw from around to draining the water. However the strange factor is that if I flush it, then plunge it a few times it will drain adjectives the water exceptionally quickly similar to normal. However if I depart from it for a while it will do the same entry where it will accomplishment like it's clogged, but somewhat plunging makes it work fine for a while.

Since the problem have started we use the other toilet for the ahhh... heavy lifting, so this is why I don't have a sneaking suspicion that that it's a clogged toilet, but I don't have the foggiest what it might be.

More than likely you enjoy a clogged or partially clogged vent pipe close to that toilet. It could be something as simple as a birds nest on the roof higher than the vent pipe. Or possibly something fell into the vent pipe and has reduced the amount of nouns that can freely flow thru the pipe. I would get up on the roof subsequent to the vent pipe that serves that toilet and have someone flush the toilet checking to brand name sure that air is vent out of the pipe. Hope this helps.
