Plumbing systems require a vent pipe that runs up through the roof of the house to open air. Venting avoids the siphon effect where one appliance draining causes suction that drains another appliance. If your vent stack is plugged it could cause the bubbling/draining of the toilet. Larger houses with large plumbing systems may have several vent stacks. There will probably be one directly over the problem bathroom. Start there and make sure the vent isn't blocked. Sometimes birds will roost on these to enjoy the relatively warm air coming up from them. If a bird fell in the pipe it could be hard to tell without running some sort of snake down the pipe.
Improper venting.
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.
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.
water that goes down drains comes from either houses (your roof drainage and gutters, and anything you use in the house such as toilets, sinks, washing machine, showers etc), and also from runoff on roads etc when it rains.
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.
It might be plumbed wrong -- or either your sewer is stoping up --
This is likely due to a blockage or a clog in the plumbing system connecting the washing machine to the bathroom toilet. As the washing machine drains, it pushes water and soap suds towards the shared drainage system, causing them to come up through the toilet. It is important to address this issue promptly to prevent any further backup or damage to the plumbing.
The washing machine works by filling with water and rotating. The operator has to put in soap, bleach and softener. The washer agitates, then spins, then fills with water, then rinses by agitating, then drains again by spinning.
your drain has a restriction in line and needs to be snaked
Yes you could, but it's usually not allowed by plumbing codes. Another point: Sometimes in Britain the outlet from a washing machine is joined to the under sink waste. I lived in a house with this arrangement once, and every time the washing machine was on you got bad smells from the drains, so I wouldn't recommend it.
A washing machine works by filling a drum with water, adding detergent, and agitating the clothes to remove dirt. The machine then drains the dirty water, rinses the clothes with clean water, and spins them to remove excess water before drying.
When the washing machine spins, the centrifugal force created forces the water outwards from the clothes toward the drum walls. This process helps to expel excess water from the clothes, which then drains out through the machine's drainage system.
