If there are any leaks, the leaking gas will “blow bubbles” at the place where it is leaking. Notice the large bubble where the head meets the bottle in Fig. 4.

Be sure to put bubbles on the following areas: Fig. 5
#1 The top of the head

If there is a leak at #1 you need a new head.
If there is a leak at #2 you need a new head.
If there is a leak at #3 you need a new head.
The reason you need a new head is that the parts which need to be replaced are inside the head, you can not get to them, and they are not available.
If there is a leak at #4 you need a new head for ISI and Mr. Fizz siphons. For Liss siphons you probably need a new valve seal.
If there is a leak at #5, in general the head is not screwed on tight enough. You may also need a new tube seal (siphon tube washer).
