Flexible condensate pipe, water collecting in low point

[ImperialHammer]

A plumber replaced our internal condensate pipe with a flexible pipe due to a leak.

I've noticed that water is collecting at a low point in the pipe under the cupboards. I thought it was supposed to be on a constant decline to prevent this as sedement will eventually build up?

It should be, doesn't sound right.

Flexible hoses can contribute to the growth of Legionella bacteria.
Pro plumber should not be using

But Gas Safe don't mean a pro plumber !

It's a boiler not AC so I'm not sure of the Legionella risk.
My main concern would be an air lock forming preventing the siphone from emptying.

Any reason the original rigid pipe couldn't be replaced?

The boiler is fitted with a condensation trap to collect debris, so just water down the pipe work.

The original pipe was fitted before the kitchen was installed going behind the cabinets. I can't see an easy way to get a new pipe in there in one piece.

I think the best bet is to also add some more clips and supports to remove any dips and improve flow.

not always true aluminium heat exchangers the condense overtime can block downstream with the amount of ali carried in the condense discharge

You could make a continuous wood lay board - don't clip because they will raise the pipe up a tad. lay the pipe and use cable ties to secure. That's plumbing - I never did get into gas 'tis what was done with lead pipe, and t'was secured by saddle clips. I used to take it out - I'm not so old as to have installed it.

There's plenty of room to do it properly, use the correct pipework and fittings.

I cannot see any problem at all, in fitting a straight piece of rigid plastic pipe in there. There is even enough height, to allow for a decent fall to the drain.
