Question about pitch of underground drainage pipe Question about pitch of underground drainage pipe. I hired a contractor to fix some water issues in our backyard. We're on a hill and he went about 120 ft around two sides of our house with this drainage pipe. It's the perforated black piping, tied into our down spouts of our gutters, with a pop top at the end of the pipe to keep rodents out.

How to Install a French Drain: DIY or Professional? How to Install a French Drain: DIY or Professional? A French drain installation is a simple process that requires a whole lot of digging. Decide to learn how to install a french drain, or if it’s worth hiring a pro. A single exterior French drain trench that’s 50 feet long means excavating about 75 cubic feet of soil. Depending on how wet your soil is (if you have a drainage problem, it’s probably pretty wet), that means 4 to 5 tons of dirt. Not only do you have to dig out the dirt, you’ll have to move it somewhere.

- Ran across this situation today on a Warranty Inspection. The picture show a plumbing vent in the attic. The vent runs horizontal for 20 - -25 feet across the attic to the vertical pipe that goes through the roof. Appeared to be plumbed to 4 incoming pipes. First question: is this horizontal run allowed. Second Question: The horizontal pipe appears to go downhill after the 'tee' fitting.

Drain and Sewer Pipe Cleanouts Cleanout Locations and Spacing. 1. Install a clean-out in every horizontal drain pipe so that the distance between clean-outs is not more than (≤) 100 feet, measured along the length of the pipe. Install at least (≥) one clean-out for every horizontal drain pipe regardless of length of the drain pipe.

- For shorter distances, the drop can be quite small. For example, a 20-foot run needs a drop of just 0.2 foot (a little more than 2 inches) for a 1-percent grade. Shorter drains may be easy to grade with the help of a good level. However, when in doubt, hire a surveyor.

Septic Drainfield Design Septic Size Requirements Guide 1 Septic drainfield trench length: The maximum length of a trench is typically about 150 feet but we have found installations that were three times that length. 2  Some writers opine that the maximum septic trench line is 100 feet.3  A realistic answer is, it depends-on site and soil conditions. Septic drainfield gravel specification: typically, washed gravel, 3/4 to 2 1/2 (pretty big) gravel is placed for a depth of 12 under the drain line piping (septic drain tile in some references).

- Question 2. The line will have to be run 1300 feet off site to tie in with the city's sewer main. The run doesn't seem to offer much in the way of major obsticles so I was wondering if there's a dollar figure per running foot we can use strictly for budgeting purposes. The project is in South Carolina if that matters.

Drainage Cost Guide If you know how to use a level it’s easier to correctly lay the pipes, but alternatively you can work back from the connection to the main sewer using pegs and calculating the rise at 1:40 (i.e. for every 40m of drainage run, the drains must rise or fall 1m). At a pinch, drainage can run at 1:60.

Tying in to a Plumbing Vent Stack Plumbing codes are not the same in every state, but most require the cross-sectional area of the vent pipe to equal at least half of that of the lowest portion of the soil stack. It's common practice in many states to reduce the soil stack to 2 inches, and extend that 2-inch pipe through the roof.

- A lot of the houses around me have a stone wall with some trees/bushes behind it and I like that look (also open to other landscaping ideas). Thinking 2-3 feet high and would be about 40-50 ft long. Shouldn't have a direct impact on drainage. You could buy the rock and do it yourself.

Technical Details: Drainage Requirements Scuppers can also be provided as primary or secondary drainage points. Scuppers are rectangular openings in parapet walls that are a minimum of 4 inches in width and height ranging from 4 to 6 inches. If the scuppers are used as primary drainage, then they are applied flush with the roof level. If they are used for secondary drainage, then they should be a minimum of 2 inches above the roof level and a maximum of 4 inches above the roof level. Once the number of required drains for the area is determined, the size of the drain inserts and plumbing should be established.
