3-phase in homes is quite common. The 220v house loads are split across the phases+neutral to balance the load.
If you're not sure go to your main DB board and check the main isolator or earth leakage breaker. If it looks similar to the below image you're on 3-phase:

If it looks similar to the below you're on single phase:

Some places may have 3x single phase breakers (one for each phase) but this is not very common - if you are uncertain best is to contact your electrician.
Powerline adaptors must be on the same phase to work, preferably on the same circuit - the shorter the distance of wiring they have to traverse between each other will determine the performance (similar to wifi, the closer to the AP you are the better).
One way to check if they will operate on the same circuit is to turn off the plug breakers until you find which one is feeding the plug points you will use, if they are on one breaker they are on the same circuit and same phase.
