Slow WC Problem

[Northers]

I am working on a WC draining through a horizontal soil pipe (about 10 ft with 1" fall can't get any greater than this due to shallow floor joists) this then exits into a vertical stack. There are no blockages and air is entering stack. My problem is a that the WC fills almost to the rim before starting to drain slowly and has little 'draw'. I'm assuming this may be due to insufficient fall on the horizontal soil pipe...is there anything I can do other than increase this? An AAV perhaps?

Any advice much appreciated!
Thanks...Northers

Hi. If its not blocked and the venting is ok and the situation allows? Try drilling the soil to within 250 mm of pan, fitting a 2" strap on boss and a piece of pipe. Flush the pan and monitor results. If ok you will have the choice of vent or an AAV. Good Luck

Thanks...I'll give it a go. If that doesn't work I suppose I'm looking at the Saniflo route...

Hi Dont go there. More trouble than there worth. Apart from blocking they will keep you awake, with the noise they transmit.

Funny enough there was a post the other day about what may help you out and that is fit a syphonic w/c, gives you extra force at out let

Or can not you lift w/c slightly maybe


As said stay away from macerators of you can,they have there place but not forst or second choice

Just checked and the only place I can see that supplies syphonic w/c's is direct from china china?

I know double trap can not be used due to ammount of water used but can you still get them ? must admit I have not seen new for years
