Hi, this is my first post. I'm having a replacement boiler installed on Friday on an outside wall of my First floor flat. I'm pretty handy with normal plumbing and other basic building skills. A GSR plumber is installing and commissioning the new boiler but to save cash I'm removing the old stuff and getting the wall, water pipes etc ready. I've talked over the condensate drain with the plumber and the options are sparse.

1./ Run it in 40mm pvc around the outside of the house and pick up the sink drain. This run would be 4m along one wall and 2m along the next before joining the 50mm sink waist which goes a further 8m to get to the soil stack. The location is very sheltered but freezing is the obvious concern.

2./ Run it vertically straight down the wall to a soak away. The problem here is that the property boundary is only 450mm from the wall. I could encroach on the neighbouring property a little as the boundary is un marked but I run the risk of getting close to their gas, water, electric, and draining supply.

3./ Run it under the floor a distance of 4m to come out on the opposite wall 2m from the soil stack. The most difficult option and the 4m inside whould be level.

My question is, Which is the best of a bad selection? The plumber recommends 1. With an air gap near where the condensate first goes outside so it can overflow if the pipe freezes.

Your views?

bTW there is no where else for the boiler to go.

Hope you're not removing the old boiler.

Your gsr will be aware of the best route as he will be the one responsible if it all goes wrong.

He has already caped of the gas for me to remove what's left and brick up the hole. By "best route do you mean the 14m run around the outside of the house?
If in 5 years time it's frozen solid during a real cold snap and I can't get hold of him whose problem will it be then?

Could use a condensate pump and run a small clear polythene tube internally to drainage Google it worth a look if your stuck

I would let the installer decide the best route. If you want to run the pipework, fine but do it on his instructions, preferably in writing. He is the one with the training and knowledge of regs. More importantly perhaps, he has the public liability insurance!

Whereabouts in the country are you? It is very unlikely that condensate would freeze in a 40mm pipe and there are other methods to protect against freezing..
