TL;DR Answer: Yes. Unless you do grey water collection (mentioned by others), which you would know about, the water that is in your toilet, your sink, and your shower is the same as the water that comes out of a hydrant on the street.

Thames Estuary

The River Thames began life between 170 and 140 million years ago during the Jurassic Period when most of southern England was covered by sea. It was during this period that millions of marine organisms were laid down to create the oolitic limestone that formed the Cotswold Hills – the source of the River.

Cool Thames Shark Facts: At least five species of shark and ray live in the Greater Thames Estuary.

The Thames Path is a National Trail following the River Thames from its source near Kemble in Gloucestershire to the Thames Barrier at Charlton, south east London. It is about 184 miles (296 km) long. The Thames Path’s entire length can be walked, and a few parts can be cycled.

Can a toilet and shower share the same vent? So yes the shower can also be vented by the wet vent along with the toilet. There is one major stipulation when wet venting multiple fixtures when a toilet is one of them: the toilet must be the last fixture connected to the wet vent.

The Dry Venting Toilet It’s advantageous to design the plumbing so that the toilet is within this distance of the soil stack so the toilet can be vented by the vent stack. Plumbers usually use 2-inch pipe for this, which is larger than the plumbing code requires.

Whether you’re putting in a tub, toilet, sink, or floor drain, they all need a plumbing vent on the drain to make it work properly. The fixture without a vent may drain slowly. The drain will likely make gurgling noises. The water in the trap could siphon out, resulting in a potent sewer smell.

Most houses have more than one toilet, and if they are on the same side of the house, their waste lines can usually tie into the same stack. If they are on opposite sides, however, each may need its own stack. Since the stacks must be vented, this would mean two vent openings on the roof.

Under the Uniform Plumbing Code, a 2″ vent can handle 24 fixture units(F.U). In a residence, a lavatory sink= 1.0 F.U., bathtub/shower= 2.0 F.U. and a toilet 1.6 gallon or less= 3.0 F.U, greater than 1.6 gallon= 4.0 F.U. So, 3-lav sinks, 3-1.6 toilets and 3-tubs/showers could be on one 2″ vent.

Requires two vertical stacks with horizontal connections from both sides, or one stack if toilets arranged over two floors, 32 total.

But how many roof vents does one home really need? A general guideline is homeowners need one square foot of roof vent for every 300 square feet of ceiling space, if your home has a roof with a vapor barrier, or 1:300. If not, you should have one square foot of roof vent for every 150 square feet, or 1:150.

4″ waste line can support 90 DFU’s, Toilets can be 3–4 DFU’s depending on how many gallons per flush. So, 22 toilets if they use a lot of water. 30 if they’re the low flow type.

Don’t worry if you do not have a vent pipe in your house, or if it is blocked and you can’t fix it. Instead of thinking about massive construction projects, you can use an Air Admittance Valve, well-known as a cheater vent. You may have heard that they are illegal and unreliable, but you shouldn’t believe every rumor.

In short, your toilet must be no more than 6-feet away from the stack if the waste line diameter is 3-inches. If the waste line diameter is 4-inches, the toilet must be no more than 10-feet away from the stack. Read on to find out more about the distance between the toilet and stack and moving your toilet.
