My new sink specs say the drains are 3 5/8 in. but when i look online to buy drains, they are mostly all 3 1/2 inch. Which size do i need? Also i bought a brushed stainless sink, but the faucets i want are not brushed although they are stainless. Will this look bad? And do i have to have a garbage disposal to get the new dishwaher installed? We are having a guy come out next week to cut out cabinets so we can finally have a dishwaher. First i was told i had to have a disposal and then i was told we could do without. I really can't afford one right now but what do you think?

Thanks so much.

Dear Shells 2756,

I am going to tell you what I think, you might not like or want to hear it.

Call in the professionals.

You have not thought this new appliance installation through to its logical conclusion.

Let me explain further if you please.

Unless you bought some fancy dandy S/S sink the strainer basket are usually standard in size but as I am not there to eyeball this you are going to have to rely on the manufactors spec's or get away from the PC and go to a supply house like a Lowes, Home Depot to shop and compare. Whatever the case may be you want the strainer baskets to match the sink and the faucet.

The same applies for the apperance of the faucet, this is a matter of personal taste and how you feel about it and not how anybody else feels about it.

No, you do not need a garbage disposal to have a dishwasher installed, at least no local where I have ever worked or ever heard of, almost all the new dishwasher's have a grinder which breaks down the food particles before they are discharged.

You are installing a new fixture (dishwasher), this is not a replacement of an existing dishwasher, IE: this fixture needs to be roughed in, not only do you need a drain you also need a hot water supply and a GFI circuit for power and a permit needs to be pulled.

So needless to say the variables you are asking answers for are almost endless.

Septic or City Sewer ? sometimes a garbage disposal is not the best thing for a septic system, depends on age and type. Local Plumber can inform you as to options.

No matter which Plumbing code is in your area, you need to discharge the waste through an air gap. Which means if you bought a four hole sink because you want a sprayer, you are a hole short. 5 hole sink versus a 4 hole. You need another hole for the Air-Gap device.

What size is your hot water supply line to existing sink and type of pipe?

Where is closest electrical supply this would be a wet area, code calls for a GFI ? Electrical Contractor.

What type of waste pipe?

Is you new sink a single, double or triple bowl?

Please do not let the trim carpenter do this work, as I can see the rubber hose, clamps and 6 miles of extension cord now. LOL

This is your house and castle take care of it accordingly and it will give you years of enjoyment and pride

The NEC does not require a dishwasher (or disposal) to be protected by a GFCI.

Those appliance are grounded and if properly installed the EGC (equipment grounding conductor) will handle any fault currents.

Only receptacles that serve COUNTER TOPS need GFCI protection. But those serve appliance that are often pluged and unplug where the cord can be come worn and they can also possible dropped in the water.

Never apply to builtin appliances.

OK< Being a woman, i didn't think a dishwasher getting installed would be a major undertaking, other than the mess of course. I never heard of having to pull a permit to do this. I was going to have the carpenter install it. I don't have any idea what an air flow thingy is, or why i would need an extra hole in the sink. You are right, i should have a plumber, but then i would also need an electrician too wouldn't i? So let's see, pay a carpenter, plumber and electrician to install 150.00 dishwasher? Don't think so. Already paying a fortune to have the cupboards cut down for dishwasher and new countertops installed and new sink. I may just take the dishwasher back where i got it!!

Dear Shells 2756

Being a woman or a man makes no lick of difference to me, this is business.

This choice is yours, you are not replacing a dish washer, you are installing a NEW fixture.

If this is no big deal than have the folks who sold you the dishwasher install it.

Yes by Law you need a permit, by law you need the Air Gap.

The concept of homeowners doing there own home repair, remodel and saving money is to fool the appraisers and home inspection people into thinking that a professional did the work. If you can accomplish this by not leaving glaring code infractions you will than reap the profits of whatever it is that you did, from a dishwasher installation to a Bath/Kitchen remodel or maybe an entire addition.

Do as you please this is not my property.

Good Luck,

Jim V
