Drill hole fill advice

Thanks for the advise. So did you have any sort of foam filling or was yours a perefect drill hole?

Sorry, I can't remember but it wasn't really relevant in my situation as the pipework was not visible.

The pipes went through an outside wall from under the kitchen sink and straight into the insulated box containing the softener. That box directly abutted the wall. There was no rear panel to the box where it abutted the wall so a tiny bit of heat coming through the wall or along any slight gap around the pipes from the kitchen would have helped to prevent the softener freezing.

Why are your pipes visible? Do they exit the wall above or to the side of the box?

Was there a reason why the softener was not positioned so it covered the exit holes of the pipes.

Also, where are the drain and overflow pipes positioned?

A water softener regularly flushes itself with salty water from the brine tank to refresh the resin and that 10 to 20 litres or so of waste water should be directed down a drain.

It should also have an overflow in case the brine tank overfills. Again that overflow should be directed down a drain.

You do not want salty water regularly discharging to the earth or whatever is around the softener.

Sharhar, can you take and post some pictures of the outside and inside views?

Thanks. Have never used polyfilla before. Would that come off or break easily if I ever want to get the pipes out or should i just leave them capped as Belenus said when I move house?

Yeah, I think it would break easily enough. You might need to refill the hole though.

How big is the gap around the pipes? For a relatively small gap a mastic filler will work or fill it with screwed up or twisted plastic bags.
