Hello kgb78_2002

You do not list your Location or Country - Easy for you do do in your Member Profile, then it updates through all Topics and Posts you make, including this one.

Health and Safety Requirements: In most jurisdictions there are bylaws which restrict drainage and sewerage pipework to be done only by a registered plumber/drainlayer.

The reason for the restriction to qualified persons only, is to ensure the works are carried out correctly and safely, that no health hazards will occur at a later date.

The local Authority would normally require drawings with a Permit Application, along with the Registration details of the qualified person who will do the works.

Records of the work will be retained at the local Authority, and may be consulted at any later date.

It is extremely easy if such pipeworks are improperly done, to have an outbreak of cholera, hepatitis, or several other communicable diseases.

Further: You have not given a plan of the existing and proposed sewerage pipe installation, and that is needed for a proper answer.

Kind Regards....

Hello kgb78_2002

If you are required to have the work done by a plumber and have it inspected that is up to you.

The large diagram below shows you need a "S" bend or "P" trap in the drain line below the sink or tub.

That "trap" passes water when the sink or tub above is drained - But not all the water passes the trap, as enough remains to retain a "water seal" after most of that water passes down past the "trap". This means that fumes from the drainage pipe and sewer etc. cannot pass back up the pipe into the sink or tub, back into the building (house etc.). The trap also dissuades many bugs, insects, crawling creatures from crawling past the trap into the sink or tub thence into the room.

The above is a general plan, which should give you the idea.

The diagram above is from: http://www.oasisdesign.net/greywater/stubout.htm

If you go to that website, you should see further diagrams, and the full explanation.

I trust that assists you.

If you need further information, reply here with

Kind Regards....

Hello bob c

Yes - There is also stubouts for Arizona included in a link on that webpage.

The website <"....http://www.oasisdesign.net/greywater/stubout.htm

Graywater Collection Plumbing and Stub Outs

Homeowners: How to construct them correctly
Regulators: How to inspect them Based on the California Plumbing Code, the Uniform Plumbing Code,

The New Create an Oasis with Grey Water (book) and the Builder's Grey Water Guide

The minor difference is in the direction of swirl given to the water, whether north or south of the equator.

All else is OK.

Kind Regards....

One must expect the water to swirl the other way, which might be an important consideration.

I have never worked outside the USA but in recent decades in the USA S traps are not allowed as they can get sucked dry by the siphone effect below the trap. P traps are required. This makes it so that on a kitchen island with a sink, and no access for a vent pipe, you must use an automatic vent valve. Even then there are some limitations. A minor point, but just for your info. -- JHF

Now wait a minute!

The diagram shows a 3-way valve... it appears that if you are going to take a shower or wash your hands you have to have the valve in one orientation, and if you are going to take a dump you have to change the valve before you flush lest your poop be sent to the garden?

That would be terribly inconvienient. It would seem if you want the option to send gray water to the sewer (or septic tank) or to the garden (bet them is some tasty mellons!) then you would tie those lines together before a 3-way valve and send one leg to the sewer and one to the mellons and the toilet (loo) would be plumbed by it's self thus never risking pooping on your mellons.

Seeing as its in India...,

The general aim is to prevent fumes/gas from coming back up the pipe into the bathroom. This is done by using the 'S' Bend (or S Trap). This holds some water in the bottom of the bend, so that any vapours, fumes do not drift up past the water trap. Assuming you install an S bend directly below the wash basin, and you have an S bend underneath the floor waste, then you can join the two pipes beyond that point, using appropriate reducers to accomodate changes in diameter (floor waste will normally be approx 50-80mm pipe and wash basin is usually approx 40mm). Note- a 'P'-Trap can also be used where height clearance is an issue. This is simply an 'S'-Bend, but the outlet is horizontal, rather than vertically down, allowing installation where you are close to the ground or floor etc.

Hope this helps :)

Is the line you trying to tap into a 4 in line or just a small 1'' or 2'' line ? You would need a digester to chop things up if under 4 ''.

You need to consult a plumbing company so that they inspect your place and suggest you the proper and exact materials needed.
