Hot and cold feeds in garage

[tomsim]

Is it acceptable to run the hot and cold feeds to a property from the kitchen to the adjacent garage to the boiler and up to the rest of the house. With regards to freezing. As long as lagged it should be ok?

Yes, as long as it’s lagged. I’ve seen some unlagged that are ok, but they’re part of a terraced row and possibly garage doesn’t get that cold.

Yes, as long as it’s lagged.

Lagging does not prevent freezing, it delays it by reducing the rate of cooling of the liquid in the pipe. In most cases the liquid is re-heated before it's temperature drops to freezing point.

Thanks for telling me something I know.

Is it pretty much standard practice?

It’s usually a water regulation (requirement) and it helps with undue warming too.

I know you know but many people without your experience who come to DIYnot for seeking advice may not know that lagging does not prevent freezing,

I would be sleeving with 22mm copper then lagging the pipes in the garage. Guess there is no real way of lagging through the cavity wall that goes from between the kitchen and the garage.

There would be, by means of a massive hole, but it would not beneficial.

Use a high quality, external lagging, like Armaflex Toughcoat or similar for best results, the thicker the better.

19mm I was going to use.
