Am I allowed to sort these two "boiler" issues?

[WaterTight]

I am not Gas Safe. Therefore I don't touch boilers apart from topping up after drain downs. Hence I don't know whether I am allowed to do anything else. Doesn't tend to come up but oddly enough it just did. Twice. Excuse the lack of knowledge of what the bits are but as I said, it aint my area, so I'm guessing.

Two different jobs. Two different combis. Both Alphas.

First one is just a weep on a soldered joint. I'm thinking either cold in or cold/hot out. Questions:

1) Am I allowed to sort it?

2) If so, do I need to order the right bit? Because it looks like I could just do it with a bent tap con and some pipe.




Second one is...I think - not sure what the correct name is - the warning pipe? I'm guessing it's the one you run outside and then bend back towards the wall. Guy who installed it didn't finish job for some reason. Customer was warned by a friend about it.

So same questions:

1) Am I allowed to do it?

2) If I am, what should/shouldn't be done (rules/regs/minimum distances/whathaveyou)?



More than happy to leave both well alone if not a good idea / not allowed.

Thanks

item 1. Technically no but yes. Item 2. No. I wouldn't touch it as probably more than those faults. If you fix visible ones the serious ones get forgotten

I wouldn't bother touching them. They have a habit of touch it and it will leak elsewhere. Is the prv pipe not going anywhere?

1 yes
2 if in doing repairs/fix and you end up with a problem that you shouldn't/cant fix you'll be giving yourself a headache

if the original installer missed this what els was missed
