Hi all,
I've recently moved into a new house and have ran into some issues with setting up my washing machine. When I first setup the washing machine, water wasn't draining properly due to the outlet drainage connection being setup incorrectly.
Originally, I thought that water wasn't draining properly because of the elevation and required pressure to discharge the dirty water into the pipe network however I believe it's related to the discharge rate of the washing machine and bottle-necking that is occurring at the spigot connection. See Figure 1 for the current configuration.
Figure 1: Full washing machine and drainage configuration
For example in Figure 3, the outflow drainage pipe has an inner diameter of 2 cm and connects to a spigot with an inner diameter of 1 cm underneath the sink. If we assume that the washing machine discharges for a specific amount of time per cycle, then the spigot is throttling the flow rate and causing water to build up in the machine.
I have tested that the pressure isn't an issue through having the pipe drain to a bucket at the same elevation as the top spigot.

If the spigot is the issue, what do you recommend doing? Getting another pipe connection with a bigger spigot diameter? Find a connection that will feed the drainage pipe into two of the spigots instead of just one in order to maintain the outlet flow rate?
Thanks in advance.
