Question about gas boiler

[snowingagain]

OK, no photo but a probably a fairly daft question about gas boiler. We had a problem with it not turning on. It turned out to be really minor, just low water pressure. Guy came over, topped up with hose, but then did an inspection and found some bits need replacing (cheap ones) and he is ordering parts. He left, leaving the hose in place, BUT the levers at both ends of hoses are in off posiition. Is it okay for me to just unscrew the hoses and replace the caps? Or is it even necessary? Like, is there (ha) no chance of a swimming pool appearing in the basement? Sorry, I am so clueless. And BTW the guy is really nice, been coming for over 15 years. But he is sick and I do not want to bother him atm. I ask as we have not put the heating on yet, but colder now. Still almost 19 in here but no sun next few days so going to get colder.

You probably need to take a photo to convey your message.

You usually need one hose to fill the water, but you are writing about "hoses" (plural). What do you mean?

Anyway: You usually have one port with a lever where you fill in the water, and one port with a lever where the (tap) water comes from. And these ports usually have caps on them.

When you fill in the water, you remove both caps, and attach the hose between those two ports, screwing it tight on the (tap) water port, but not so tight an the filling port.

You then open the (tap) water port, accepting that there is a little bit of water coming out of the not so tight filling port. No slowly open the filling port with that lever while at the same time screwing the hose tight. The whole "not so tight in the begining" hassle is to ensure that all air is out of the hose (and doesn't end up in the heating system), and to ensure that no soiled heating water gets into the hose or the tap water system, because that water is smelly.

Once you've reached a sufficient water level, close the lever at the filling port first, then the lever at the (tap) water port, remove the hose, wipe away all water that has gotten on the ground, put both caps back on, and you should be done. While you're at it, it is also now a good time to bleed the radiators.

Thanks F. I meant one hose. I was not at the house when the hot water stopped working. Nice guy came and it was just low pressure easy stuff. But this was in August. He said he was coming back soon with other parts that he had identified as faulty. Great guy. But not come back. He is sick now as I said. What I kind of need to know, is if is okay to turn the heating on. I think I am ok to remove hose and screw in the brass taps he left in obvious place. Sorry for being thick.

Leave the hose where it is for now.
Switch on the heating system.
You might have to bleed the radiators after refilling.
And that bleeding might need a new refilling.
That's why I suggest to leave the hose as it is for now.

And it all worked beautifully which was a relief as it is getting on a bit. But today the sun came out and it has warmed up beautifully. Thanks for your advice and patience.
