Kitchen sink gurgling and overflowing from air inlet

Hi there,

So I have thrown several methods of drain cleaning from each side of the sink which has improved the issue but it still persists.

When draining larger amounts of water from the kitchen sink, or when the washing machine drains out, water starts backing up and coming out at point one.

Also as water does drain away lots of gurgling from point two.

Thinking drain is clear but a vacuum is in there somewhere stopping water from draining quickly.

Dismantled as much as I can and cleaned lots of crud out. Also used auger from front of house and cleared out a load of gunk and smaller auger down the pipe under sink as far as I can.

The spigot at point one is an unused connection point for an appliance waste pipe ( such as a washing machine waste hose). It should be capped or sealed ,and not open ended.
I can't make out what is connected to the top of the standpipe ( point 2) ,what is it ?
Your pipe work is blocked ,or partially restricted somewhere if the sink doesn't drain quickly.

point 2 is a pipe coming from outside the house I think. we have an outdoor tap so thought it would be connected to this in some way. Ill double check it when I have a break
 
Possibly the condensate drain from a boiler ,not going to be connected to an outside tap. Hard to see with that thing hanging down in front of it.
 
Once the pipe goes outside what is it going into, I think that is blocked. maybe frozen up ?
