Hello everyone

I am Louise a member of Joe Public but wanted to ask a question. Similar issues have been discussed here before.

Situation: I live in a basement flat and want to move my kitchen from the room at the back to the middle room. It will need to be plumbed for a double Belfast sink, dishwasher and washing machine situated in an island about 1.5-2m away from the external wall at the back which is nearest to the drain.

Layout of the flat three rooms one after the other with the bedroom at the front (which I want to turn into the lounge) middle room is the lounge (which I want to turn into the kitchen and have bifold doors inbetween) and the last room at the back is the kitchen which I want to make into a smaller bedroom. Long hallway to the side on the left as you are inside with the bathroom at the end of the hall.

Current plumbing: At the back where the kitchen is currently situated the sink and washing machine pipes go partially around the outside of the room under the floorboards and empty into a drain underneath the floor. I have never seen this but it can't be completely sealed as I get intermittent horrible eggy smells coming up from the floor. I understand this could be sewer gas.

The fresh water comes in from the front of the flat down the hallway at ceiling level through the bathroom and then into the kitchen at the back.

There is also another drain outside the back door which leads off the kitchen.

My thoughts - is it possible when the rooms are changed over to have the pipes drilled under the floor in the middle room and through the external wall to drain unseen into the drain that is outside the back door? There is a rain pipe that would also need to be moved slightly to continue to drain into this outlet.

I also want to move the radiator to behind the door and have a vertical one.

The fresh water could be rerouted in the bathroom to go under the floor to the right to go into the middle room.

Questions:
Is this doable?
Any thoughts on how much this would cost in Lewisham south London.

I hope the layout makes sense. Any advice much appreciated.

Thanks
Louise
 
nobody is gonna give you price without seeing the job in person, but sounds doable ,but not easy. Would probably fit pump to pump waste away under the floor. Best would be to get somebody in and get professional advice.

Do not use a Saniflo pump in this installation.
 
There are 2 units for kitchen waste in the Sani range and Sani say that ANY vertical (even an inch) must be within 300mm of the pump and only one vertical lift is allowed so you can`t come out of the pump run the outlet down, along and back up again and if you are going to run all the pipe along to the drain under the floor then were talking around 550 - 600mm under the floor so I hope you use big bore pipe or supply a rodding eye. Not that I care as London isn`t my area.

Seen one buried under the floor and then cemented in to stop it moving (so the guy said), they had even cemented over the 2 screws holding the pump / motor in the tank, walked away laughing.

There are some nice little pump systems around where the tank is underground and they have circular or square lids which sit flush with the floor and a high level warning buzzer on a wall for when it goes wrong. The downside is the smell in the room when you remove the lid.
 
Very true, just saying I wouldn`t recommend a Sani to both customer or installer for this installation :wink5:

(Hope Louise hasn`t had a sex change)
