Moving Bathroom...stupid question!

[kfreeman]

Hi all,

I'm a complete novice when it comes to plumbing and associated issues. I still more to the carpentry side of things. That being said I do like a challenge and am a quick learner, with that in mind have purchased a wreck of a home to modernise.

Part of my plan involves moving the existing (monstrously sized) bathroom into the centre of the first floor in order to create space for a bedroom. As the house is a semi this would mean the bathroom would have no window and sit against the adjoining wall with the next door neighbour.

I am just worried about locating the soil and waste pipe for the toilet and bath. This is going to sound so simple and stupid but I believe that if you don't ask you'll never know...so here goes... Would it be possilble run these pipes under the floor boards to then join the main pipe (which I'm sure will have an official name) outside?

Would be grateful of any advice!!

If you mean notch them through the joists then unlikely.

Work on all the falls being 1:40
You'll need ducted vent too - but everyone will hate a fan in the room so put it elsewhere.

Thanks, in which case would the only option be to take the pipes through the property and sympathetically box in? (if there is such a thing)

Thanks for the link I'll have a good read through once I'm armed with a nice cup of tea! I think I've turned plumbing into my nemesis. Time to take the bull by the horns!

Where would you recommend locating this?

If you can go in the direction of the joists you may get the 1in40 self cleansing velocity sloap for the 4" soil pipe depends on the distance.

You can box it in otherwise but depends if doorways are in the path.

You can put the whole bathroom or just the wc on a raised plinth to help with the drop.

due to the distance from the vent, when you flush the loo the water may be sucked from some or all traps, but if you use a hepvo trap in the basin this will act as an air admittance valve, which allows the suction of the large flush down the long run to be replenished by air from the atmosphere instead of via the water traps.

Whatever you do don't use a macerator they were designed by a sadist who likes plumbers to be covered in the product of your toilet habits.... I refuse to go to them, with good reason since I was covered top to toe in the households toilet waste proiducts of the last few days as though it had been made into soup with a blender. It's that blue stuff which stains your skin that bothers us most, funnily enough..... After one experience like that not many of us go to macerators. I tell people to ring the manufacturer.... It's their fault for making it.

My a*se has departed from my body as a result of about 10 minutes of unabated laughter.

Amen to that

 

[Paul Barker]

You only go there once don't you?

I mean toilets are OK, we sometimes have to take a cold chisel to them and a handsaw to cut the pipe back so the new close coupled unit will fit, but a little brown stuff on the colkd chisel and the saw does nobody any harm, just put them in a bucket. It's the watery soupy you know what allsorts that is disgusting.

 

[Softus]

Too right - the stuff that has the same consistency as that apocryphal quicksand that they used to use in the old black and white Tarzan movies, only brown in colour, and with a sanitary towel floating in it instead of the Panama hat from the 'sand's last victim...

I'm so glad I joined this forum!!

I do feel for you plumbers for the below...

covered top to toe in the households toilet waste proiducts of the last few days as though it had been made into soup with a blender. It's that blue stuff which stains your skin that bothers us most,.

But I'm going through exactly the same thing myself except the blendered nasty isn't coming from a toilet but from my 6 month old son who's just been introduced to solids...no matter how hard you try it ends up everywhere!!

As for the blue stuff I use the green as it matches my tiles better. Any aversion to that?

 

[Paul Barker]

That's the one.

Reminds me of the sea up the road at Scalby Mills.

Somewhere between me and that macerator spill.....?

I meant loft, cellar, ouside....

Depends - does utter contempt qualify as an aversion?

If you hate your diaphragm washer that much, why not just hasten the process and fill the cistern with TCM?

 

[kfreeman]

So to summarise:

It may be possible to go under floorboards providing 1:40 can be acheived, raising loo can help achieve this and to make sure the noisy fan goes elsewhere....oh and to avoid macerators like the plague!

Now for the impossible question; is it a job for a professional or something worth having a go at?

 

[Paul Barker]

Depends on the skill of the person doing the job. It would be a devil of a job for us. If you get profesional estimates they will be high, it's the sort of job we avoid.
