Intermittent slow draining toilet

[Mike Renwick]

My downstairs toilet has suddenly started draining slowly (it's been fine since we moved in 3 years ago). It now take about half a minute to empty the bowl, and doesn't cope well with solid waste/toilet paper. At first I thought it was a blockage, as it seems to clear it after a good plunging. However, I come back to it some time later and it's back to draining slowly? This has been going on for weeks. It's the fact that it's so intermittent that's confusing me. Even without use it will go back to draining slowly...?
Tried plunging (various types), drain snake (useless), drain cleaner (no effect).
Any ideas?

Blockage somewhere. Have you lifted the manhole cover outside and had a look see?

I haven't managed to get the cover off. The screws are jammed in on one side... Not sure I'd know what to do if i could get it off? Sounds like that may be the next stage though?

Thanks

I would say so.

Get a jetter company out. Sounds like a blockage further down

Don’t need a jetter. Some decent rods will fix that .

Should do, even if it doesn't it's character building!

Depends on blockage. Tree roots - no chance, Wipes - optimistic, fat/grease - will take some doing.
