My son has just bought a flat and I'm in the process of redecorating before he moves in. I've noticed that when you flush the loo the water rises quite high in the bowl and goes down a lot slower than it should. I've not used it in earnest yet and I image that any solids wouldn't get flushed away as they should. I'm guessing there's some sort of blockage in the u bend of the wc. I've not tried anything yet but was thinking of having a poke with an old bit of hose or something. I'm open to suggestions though. Is there anything made for the job or perhaps some chemical treatment I can use?
Thanks
John
