How can I drill a 2" hole through a window?

[garagefela]

Hello everyone,
I am in the process of reusing the waste water from my laundry into the garden.

The problem I have is that my house sits on a concrete slab and all the laundry plumbing is inside the slab with no access to it. The only option is run a pipe directly from inside to outside. The only way I can do that is to drill a hole in the window and run a 2" pipe through it.

Through the window is the only way as the whole laundry wall to the outside is glass (door and window roof to floor) No actual wall is there.

This will be a one off so I am looking for a solution to get through the glass. The pipe is actually 50mm and will want to drill it a bit bigger to fit in a rubber grommet.

I have not yet looked for grommets but lets say I find one that is 60mm for the sake of this exersize. I am thinking that this might work, turn up a section of solid PCV into a 60mm pipe and on the other end 1/2" to fit my drill.

On this tool use valve grinding paste to slowly drill through. I realise that diamond compound will be the best but it is just the one off and as long as I can get through it without busting the window I will be happy.

All comments for and against welcome,
Cheers M

You can use a dentil drill with diamond bit to cut the glass....a bit tedious, but doable if you are very patient. Otherwise, break the window & replace with plexiglass. Cut hole with 2" hole saw. Seal pipe with silicone.

Take it to a glass shop and let them do it, if it's removeable. Shouldn't cost much.

Hi,
Yeah unfortuntely I can't (really,really don't want to) take the window out as it is about 4 feet wide and 7 feet high.

Replacing the window is a bit out of the question as it the cost outweighs the benefits, if it was smaller, yes I would do it. Good suggestion though.

Diamond dental bit or similar hmmmm might do I will hunt around, thanks.

Just a thought...are you sure it is not tempered glass? Big windows sometimes are for safety reasons.

[garagefela]

If I had to say I would say it is just normal old glass. Have accidently broken a window in the past and it was normal glass. Thats not to say that this window isn't toughened but am leaning towards it not being.

Thanks for the replies,

Obviously diamond bit will work but will my way work at all just wondering?

DO NOT DRILL IN THAT GLASS. Any glass that runs from the floor to ceiling should be tempered glass and that will shatter if you drill it. Your best bet is to find a different way to route it, like through the wall next to the glass wall and use an offset bend in your two inch plumbing or call a glass shop have them fab ya a glass with the hole and have it sent to be tempered. When installing watch the edge of the glass as this is very fragile and can shatter when in contact with concrete or steel. Good Luck!!

Hi garagefela

I found this website

http://australianglasstools.com/Glas...ids.html#G1901

and they are in Scoresby which isn't your neck of the woods but they may sell to glaziers in Hoppers or know of a glazier in Hoppers that could do it for you.

Does your grey water system look as proffesional as this (its the prototype)?

PS See ya at the next BBQ

Derek,
Your setup is a piece of garbage. Get it.

Due to the setup of my block I need to run my water outside and collect it in a sump and utilising a sump pump, pump it direct to the garden or a holding tank with another pump to use as I see fit.

Sump pump with a tank is preferred, at this moment getting the water outside is the hard bit.

I had no idea the glass was that large...I would definately think of doing something else...If you are in a basement, that means that you have a floor above you & joists...you should be able to run something along the ceiling/floor and get it outside. Worst case, you drill into the corner of the room above, run the pipe out the outside wall & just make a cover to go over the plumbing on the 1st floor.

Hey garagefela

I forgot to mention that all of the fittings for doing irrigation type connections are best purchased from a plumbing supplier NOT from Bunnings. Bunnings range is SH_T and all of the the time you spent FAing around trying to find what you wanted could have been better spent at a plumbing supplier. I used Reece down in McIntyre Rd in Sunshine and they have got EVERYTHING you could possibly want in fittings so I reckon you won't have to make your own grommet. Their prices are fair and for the convienience of one stop shopping quite reasonable. Friendly staff too.

I got sick of looking at my old wheelie bin grazing in the back yard so I put it to good use.

Cheers

Yeah been doing my own plumbing bits and pieces since forever, since Dad taught me all those years ago anyway. He was not a plumber either just a fitter that knew how to do everything.

Shhhh don't tell all those registered plumbers out there or I will go for a row.

Reece and Bentons are down our way and I always ask for trade price and have never been knocked back yet, asking never hurts.

Spent some of the afternoon lifting out the bathtub, need to get a 50mm pipe out of the brick wall and off to the sump.

Makes me mad when I go to some peoples houses and the pipes are all on the outside of the wall. Oh well I am stuck doing it the hard way.

Cheers M
