Hi,
I am planning on turning a ground floor toilet into a wet room with central gully. It will be used ocassionaly in addition to the main bathroom but also to wash feet and as a drying room. Room is approximately 1.5 by 1.2m
Original toilet mid 1970s was cemented to teh floor discharging into clay pipes straight into the nearby chamber, which is about 700 mm below ground level, so falls within the BRs for not needing a vent stack.
I dug the clay and the concrete with intention to rebuild the floor with insulation but no UFH.
My plan is to drop ground level, teh material underneath is quite good aggregate mix of sand and stone. Probably overlay with another 50mm of type one, well compacted, sand blinding, DPM, 100mm insulation, DPM, 100 mm concrete slab, 70ish mm screed with falls to be tankes and tiled.
I am planning to use the McAlpine TSG2-T150SS trapped floor gully, 75mm water seal.
Heres my question, I drew Option one and Option two of the underground drainage.
Is Option 1 viable, I think not as it lacks roddability for the washbasin branch. Toilet branch can be rodded fromthe outside chamber and the gully branch can be rodded once the internals are taken out.
Is it better to use option 2 (not absolutely accurate dreawing but shows the intent) to discharge the washbasin in one of the pan connectors that comes with a boss? Similar to: Bossed Pan Connector
Or is it something else?
