Unless you know that there is one in the line before it gets to the main line, you should. Sewer gas can come up that drain just like any other.
You can drain it directly into a drain pipe. Just make sure the the top of the drain pipe is even with the top of the washing machine. If not, the water from the washing machine will drain all of the time. There is no valve in the machine to stop the water from draining. The washing machine drains using a pump motor.
Draining refers to water falling due to gravity so you can't technically drain a washing machine to an overhead drain. However, washing machines don't really drain. The water is pumped out and up and can therefore be discharged to a drain that is slightly higher than the washing machine itself
The drain is getting plugged and the toilet is lower than the washing machine drain so it is easier for the water to come up in the toilet than to go straight out the drain. Put some drain cleaner down the drain where the washing machine drains and that may solve the problem.
None, but you could install a transfer pump to the drain hose of one.
what would be needed to drain a washing machine up from a basement? We have power and water, as the water heater is in the basement, but the drains are about five feet up.
LED is working with the use of washing machine. It just circulates the flow of water from east to west and vice versa. After the circulation you can now drain the washing machine for a new cycle.
Washing machine drains into a floor drain? The drain need cleaning. Liquid drain cleaner may do it, or it may need to be snaked. Simple fix is to get a 30 gallon trash can, cut a small hole in the bottom, the size of a quarter and set it over the drain. Let the washer drain into that. The small hole will let the water drain at a rate that the floor drain can handle it.
the water calve could be going bad or you could have a siphon happening from the drain line.
The washing machine is pumping out water faster than the drain pipe can handle. A trap in the drain pipe to which the washing machine hose is attached is required and that makes the water flow slower than you might expect. Having the washing machine some distance from the main drain line requiring a long horizontal run in the machine's drain pipe will also result in a slower flow. Other causes could be: undersized waste pipe, backward wyes or santees, backgraded piping, backed up gray water system. An obstruction such as a checker piece or poker chip could be lodged within the pipe. Such an obstruction acts as a valve or flap that will pivot out of the way when a snake is pushed through the pipe but pivot closed when water attempts to flow through. Nowadays a two inch drain pipe is recommended. Some cities require two inches or larger. Do not seal around where the washing machine hose is hooked onto the drain pipe as this could overload components within the machine.
overfilling
Because the washing machine drains down the same main drain and it's suction as it goes by is trying to suck the water out of the under sink U trap.
Drain on the dial of a washing machine usually just means it drains the water out that is currently sat in the bottom of the machine allowing the door to be opened or to become empty
