Need help on how to replace/update kitchen sink plumbing?

15 years ago

Hello,

I need help on how to DIY replace (update) all the stuff under kitchen sink plumbing.

If I wait any longer for my DH to do it, the kids will be in college (theyÂre 4 and 2 right now).

I appreciate all and any help as to how to do the following:

- the current plumbing looks like PVC, but they look old (but not leaking yet)

- I need to replace the faucet, from a 2 handle one (with 3 holes) to a single handle one (with 1 hole)

- Put in a water filter, and replace the current faucet spray with the water filter dispenser

- Put in a soap dispenser into one of the current faucet holes

- Put in an InSinkerator Instant Hot faucet tank and dispenser into the other current faucet holes

- AND install a Tapmaster (where you turn on/off the water by pressing on a foot pedal)

I am very left-brain and know that I can do it; I just need guidance.

Besides turning off the water, removing the p-drain under the sink and taking it to ?Lowes or someplace to get identical plumbing, what else?

I spent all of the money on the faucet, water filter/dispenser, Instant Hot, and Tapmaster, so thereÂs nothing left in the budget to hire a plumber.

But in case I did, what is your best guess on the cost/number of hours it would require a plumber to do this in the NorthEast/MA area?

I really appreciate your help.

Do you own a basin wrench?

Do you have individual shut off valves to the hot and cold water under the sink? Do they just have the one outlet? Or do you have a DW coming off the hot and a ice line for the fridge coming off of the cold?

What type of supply lines do you have? Copper? CPVC? Pex?

Are you keeping the same sink?

Have you had a dedicated electrical circuit run for the InstaHot? (that means it's on it's own wiring all the way back to the breaker box)

If you're replacing the sink, and it's a drop in, it's a LOT easier to mount all of the stuff into the sink holes and then drop the sink in and secure it than it is to bust your knuckles working with a basin wrench behing the sink. PVC waste piping rarely needs to be replaced. It doesn't get old and brittle like galvanized does. Most likely, you can reuse the drain piping just fine, or just leave it alone if you're not replacing the sink or disposal. IF you're replacing the sink with a deeper model or replacing the disposal with a taller model, it's possible that you may need to open up your wall and redo your waste line going in to the wall so that it has the proper fall with which to drain.

Answer these questions, and you can be a little further along with your project.

live_wire_oak: thank you so much for your response.

A few pictures:

What is all the white stuff? What does this valve control? The dishwasher (DW) is to the Left of the sink, so is that the hot water line to the DW?

Doesn't the drain to the sink looks like it's corroding on the bottom? And doesn't all the connection on the PVC look dirty/about to fail?

Do you own a basin wrench?
- Yes, I can borrow one.
Do you have individual shut off valves to the hot and cold water under the sink?
Yes, 2 shut-off valves.

Do they just have the one outlet? Or do you have a DW coming off the hot and a ice line for the fridge coming off of the cold?
- Yes, a DW coming off the hot line, but NO ice line for the fridge off the cold line YET.
- (for the future Â about 5years from now, when we hook up the all-freezer, weÂd like the ice line coming from the water filter line:
1. is that possible?
2. should we set it up now, knowing that when I hook up the freezer/ice line, itÂll be w/ a whole new sink in a different location?
What type of supply lines do you have? Copper? CPVC? Pex?
- The immediate supply lines are ?flexible (see pictures).
Are you keeping the same sink?
- Yes, itÂs an integrated Corian sink to the countertop. WeÂre keeping it for ~5 years. Then IÂll have to do this all over again when we put in new stainless steel sink and seamless stainless steel countertop/backsplash.

Have you had a dedicated electrical circuit run for the InstaHot? (that means it's on it's own wiring all the way back to the breaker box)
- No, I donÂt. Is that required for code?
- Any thoughts/possibility to connecting it to the DW electrical line? My DW has its own switch (like a light-switch) that controls the power to turn it on/off (childproof reason).

PVC waste piping rarely needs to be replaced. It doesn't get old and brittle like galvanized does. Most likely, you can reuse the drain piping just fine, or just leave it alone if you're not replacing the sink or disposal.
- See picture: looks really old, threatening to leak.
- No disposal (septic system).

I appreciate any and all help.
Thank you so much.

Questions regarding plumbing of a new kitchen sink
Q

Just slap some pipes together! (Just kidding - don't do that!) Based on your "new DIY" posting, I'd strongly suggest getting some help to learn. Even hooking up a plain old sink for a rookie can be a challenge - this is tricky in several respects for a novice. (too many places to have leaks, for one thing).

Replacing center-drain kitchen sink with an offset-drain sink
Q
Comments (9)
Thanks, Vith. The goal is to gain counter space to one side of the existing sink cabinet, and I thought we might gain enough by shifting the sink cabinet as far to one side as the existing plumbing (inflows) allows. We may end up moving plumbing anyway, but we're on a tight budget so I was looking at less costly options. But if I understand correctly, you're saying the drain could still be in the center of the sink; is that right? I like the fact that an offset drain allows you to empty the strainer without removing, say, a large baking sheet from the sink, so I may opt for the offset drain anyway. I thought it might also simplify the under-sink plumbing as well.

Need help finding a replacement kitchen sink by size of sink cutout
Q
Comments (6)
Sincere thinks to you all for the feedback. After doing more sink research, I found out that the new sink's cutout size had the smallest cutout size of all for the double-basin SS sinks I was looking at. I bit the bullet and found a handyman who came out to enlarge (dry cut with a shop vac) the granite. He was able to do it in <30 minutes., just by cutting 2 sides. It did cause a lot of dust, even with us prepping the kitchen area by removing everything from the counters, open food items, plus hanging plastic tarps on all sides of the kitchen to contain the dust to the area. The edge of the cabinet under the granite got slightly damaged but is still hidden, and the sink now sits flush to the countertop.

Need help/input for updating honey oak country kitchen!

Jhmarie; yes, the kitchen is very functional, and a part of this is almost like therapeutic processing for what to do with this house!Thank you for the heads up about the book. I will have a look for that. Aprilneverends; well thank you. I am really trying to not get caught up in fads, but I think the state of the place made me focus on the yellowness of the oak. And the oakiness of the oak everywhere in that part of the house! I always really enjoyed this blue, to be honest. ha!! It contrasted nicely and I got to cackle in my husband's direction every time someone told me they loved it, too. That's the thing I guess, you never can tell. I am a bit leery of how much the kitchen will change with all of the white and off white in regards to the contrast, and had to kind of giggle at the thought of painting the walls white and the wainscoting blue. Like a role reversal. :D Fidlfreek; I appreciate you bringing me back down from the clouds with some of your suggestions. Some of your sentiments I had thought of and was considering - all white miracle method, subway tile, lighting updates. Now is the time to pull that big beast down I think - we are planning to paint the ceilings throughout the home. Curious of your thought process- the lighting fixture you linked from ikea, is that to coordinate with the current colored cabinets? Or the shape in general? Staining the cabinets darker is of course an option, I just don't want this area to feel any more boxed in, I guess. This vantage point is actually the only way in and out of the kitchen - there is also peninsula seating already to the left, FYI. I actually picked the flooring you circled in the event that I wanted to go lighter or darker with the cabinets, now or later, that there would be flexibility in the flooring color to do so. It's also more of the classic wood look than some of the on trend colors I am seeing out there. The more I think about it, the more I would like to NOT spend a lot of time painting everything white, but I definitely think I need some adjustments in here. I find it interesting that none of you have mentioned the appliances or their color - apart from the microwave, which is usually the least of the appliance worries. ;D I so appreciate your feedback and input.

The PVC looks great under there, no rust, rot or corrosion. May be just a litle dirty but no great deal. On the Insta-Hot you should have literature specifying what it needs in the way of hookup on the water and electrical. At the least it should say how much power it draws.

MY concern would be the extensive corrosion on the copper, especially on that lower cutoff valve, you'll want to replace that with a decent ball valve, they don't leak like the regular ones do. I think the staining on the pvc is probably from the sink, if you're keeping it, you'll want to redo the seals on the drain.
