Subsection 701.2(2) of the California Plumbing Code, 2019 Edition, is hereby added to read in its entirety as follows: 701.2(2) Drainage Piping. ABS and PVC DWV piping installations above ground shall be limited to residential construction, not more than two (2) stories in height.
Can plumbing be above ground?
Above-floor plumbing systems eliminate the need to break through a concrete floor to install drainage below. A macerator or a grinder located behind the toilet reduces the waste into a slurry and pumps it through small-diameter tubing straight to the drain line.
Can sewer lines go uphill?
The distance the water will travel determines the horsepower of the pump. But you may be able to drain by gravity, if the sewer line uphill is low enough below the surface of the ground. Everything will need to be determined by an estimator.
How do you cover an above ground sewer line?
How to Cover a Sewer Pipe in the Back Yard
- Cover the main pipe with a couple inches of gravel.
- Sprinkle grass seed over the soil by hand or with a seed spreader.
- Cover the grass seed with a light sprinkling of straw.
- Hide the sewer pipe access point with small shrubs or a combination of fake and natural rocks.
Can you use PVC for sewer line?
Regular schedule 40 PVC pipe (here) is perfect for drains and wastewater. Like ABS pipe, PVC pipe is used for drain, waste, and vent piping systems and as insulation for electrical cables. It’s versatile and durable and the choice for professionals and DIYers alike.
What is above ground drainage system?
Above ground drainage systems usually take form of guttering and downpipes, for rainwater management, and soil & waste systems for taking wastewater from properties to the below ground sewer system.
What kind of pipe is used for sewer line?
PVC and ABS – There are two types of plastic pipes that are used underground for sewer lines. PVC and ABS are quite similar, though they have different codes and use different adhesives. They also differ by color – PVC is white and ABS is black. In general, PVC is more flexible and ABS is stronger.

Can Schedule 40 PVC be used for water supply?
Most schedule 40 PVC found in homes and offices is white pipe with a National Sanitation Foundation (NSF) rating for potable water. The drawbacks with this type of PVC pipe are that it will degrade when exposed to short wave UV light (contained in sunlight) and at higher temperatures, it will soften.
How high can a sewage pump lift be?
Typically, 1/3 HP pumps can handle 7′ – 10′ vertical lifts from the sump pit if they have one 90-degree elbow and a horizontal pipe run between 3 feet and 25 feet.
How do you make sewage uphill?
Making Sewage Go Uphill Before Turning It Back Into Gravity?
How do sewers work uphill?
When the gravity sewer mains fill this basin, the pumps are activated by level switches. A switch is activated and the pumps pump the wastewater through a pipe called a force main. The force main pumps the waste water uphill until gravity can take over again.

How long will schedule 40 PVC pipe last underground?
The Water Research Foundation reported that 100 years is a conservative estimate for a properly designed and installed PVC pipe.
Why is ABS pipe no longer used?
The State of California has banned the use of “regrind” or recycled plastic resin for use in ABS drain-waste-vent pipe. The new law stemmed from major problems with pipe failure of recycled-content ABS pipe made by several companies during the 1980s.
Will schedule 40 connect to sewer pipe?
Schedule 40 PVC pipe is the standard strength/thickness pipe used in most household sewer lines.
How high should a soil pipe be?
Soil pipe installation regulations
Soil pipe Building Regulations state that the soil pipe is always placed above the highest water inlet into the pipe, and that the opening of ventilating pipes should be at least 900mm above any window in a dwelling that is within three metres of the pipe.
What is surface drainage system?
Surface drainage systems are canals that are created for runoff water. They contain shallow ditches that are dug in a parallel pattern. Knowing the different types of surface drainage systems, their purpose, and how to choose will allow you to decide on the best route for a given property.
What is a drain hopper?
The hopper is a drainage fitting with an open top and an open base, where the base opening is typically smaller than the top. The bottom piece is stationary and the top lid moves back and forth as the bridge expands and contracts due to thermal movement.
Do sewer pipes run under houses?
They are usually behind the houses by a few metres. Sometimes people build extensions over them (this is not actually allowed). In terraces they usually run behind all the houses, parallel with the road, then come forwards to join the sewer under the road at the end of the terrace.
How deep should a sewer pipe be?
Sewer lines on private property can be as shallow as 18–30 inches deep or as much as 5–6 feet deep. In areas with cold climates, the pipe will be buried deeper to prevent freezing in the winter.
How long do PVC sewer pipes last?
Clay pipes typically last between 50-60 years, while PVC pipes are expected to last 100 years before requiring replacement.
Can water line and sewer line be in same trench?
Water and sewer lines must be a minimum of ten feet apart; they are not to be laid in the same trench. When a potable water line crosses a sewer line, the requirement is to provide two feet or more of clearance.
How deep does PVC have to be buried to drive over?
12″ from the top of the pipe to the underside of the road surface is the minimum depth at which PVC pipe with traffic loading can be buried. Pay close attention to the placement, selection and compaction of flexible pipes at shallow depths below rigid road surfaces.
Will PVC pipe freeze underground?
PVC pipes are in danger of freezing when surrounding temperatures approach 20 degrees Fahrenheit. Ice begins to form and gradually blocks the pipe. This blockage causes a rise in water pressure. Eventually the pipe ruptures and sends water everywhere.
Can you drink water from PVC pipes?
PVC is a cost-effective and durable option for potable water (Drinking Water). For this reason, many thrifty contractors and home improvement enthusiasts turn to PVC pipe (product) and CPVC pipe (product) for their home plumbing needs.

When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corrode. – Price. When you compare the material costs of PEX vs PVC, PEX comes out more expensive. (However, balance this factor against the lower labor cost to install PEX.)
Can GREY PVC be used for water?
Gray conduit is not rated for pressure pipe applications and may not be suitable for potable water use. Stabilizers and other ingredients used in conduit PVC may be toxic; conduit PVC is not held to the same drinking water standards as NSF marked pipe and should not be used in potable water systems.
