The drain pipe should be a minimum of 1-1/2″ I.D. (inside diameter) to ensure proper draining. The washer drain hose is a 1-1/4″ O.D. (outside diameter). To be confident that no siphoning of water will take place, the drain plumbing must be a minimum of 30″ high for Top Load washers.
Can a washer and toilet share the same drain?

How many degrees does a drain pipe need to fall?

Can a washing machine drain be too high?
A washing machine drain can be too high to pump. Washer drain pumps have a specified power rating, so they can only pump out water at a certain flow rate for a particular drain height. If the drain is too high, the flow rate will be too low to push the water out of the washer, resulting in backflow.
Does a washing machine drain need a P-trap?
If they omit the trap and vent, it’s a mistake that can cause problems on two counts. The lack of a P-trap exposes the area to sewer fumes and the lack of venting will cause the drain to run sluggishly and overflow. Washers, like all fixtures, need a trap.
What happens if washing machine drain is too low?
If the drain is too high, the machine won’t be able to propel the water up through the hose. If it’s too low, the water will flow right back into the drum after being pumped out. Either of these scenarios will result in a washer that stays full of soapy, murky water.
What happens if a drain has too much slope?
Backups: When the slope is too steep or not steep enough, backups can occur, preventing liquids and solids from draining. Excessive erosion: When pipes become clogged due to an improperly sloped pipe, water may be forced around the pipe, causing extreme erosion to the surrounding soil and bedding.
What angle should drains be?
What is the recommended fall for a soil pipe? The minimum fall for a waste pipe is 1 in 40. The maximum fall is 1 in 110 (apart from vertical pipes but that’s a different story). So pipes with a gradient between 1 in 40 and 1 in 110 should have adequate flow to prevent blockages from occurring.
