Kitchen Sink Money Drain: How Much Did You Spend Replacing Yours?

Totally get what you mean about the paranoia - once you’ve had a drip or two, it’s like you can’t trust anything under the sink. I spent more than I planned too, but honestly, peace of mind is worth a few extra bucks. I did try to reuse some parts where I could, just to keep waste down, but those push-to-connects are hard to resist when you’re on your back in a cramped space. Sometimes convenience wins out over budget or even eco-ideals... but at least it’s done right and hopefully for good.

I did try to reuse some parts where I could, just to keep waste down, but those push-to-connects are hard to resist when you’re on your back in a cramped space.

- Been there - reused a trap once, ended up regretting it when it cracked a month later.
- Push-to-connects are super tempting, but I always wonder if they’ll last as long as the old-school stuff.
- Honestly, sometimes I think the “peace of mind” is just the price of not crawling under there again for a while...

I’ve always wondered about the long-term with those push-to-connects too. They’re a lifesaver when you’re wedged under the sink, but I can’t help thinking about what happens five or ten years down the line. Are they really as solid as the old compression fittings? I’ve had mixed luck - one held up fine, another started weeping after a couple years and I had to redo it anyway.

I get the appeal of reusing parts, especially if they look decent, but plumbing plastic just seems to get brittle over time. Maybe it’s all the hot water and dish soap? I tried to save a few bucks by keeping the old tailpiece last time, but it ended up leaking at the threads and I had to make a second trip to the store. Not sure it was worth the hassle.

Curious if anyone’s actually had a push-to-connect fitting last more than a decade under a kitchen sink. Or is it just one of those things where you trade convenience for longevity? Sometimes I think about just sweating copper again like my dad did, but then I remember how much faster these new fittings are... Is it just me, or does every “upgrade” come with its own set of headaches?

I hear you on the push-to-connects, but honestly, I think they get a bit of a bad rap. I’ve seen a few go the distance - like, 12 years and counting under my aunt’s sink, and she’s not exactly gentle on her plumbing. Maybe it’s more about the install than the fitting? I’ve seen more leaks from overtightened compression nuts than from push-to-connects that were just snapped on right. Still, I get the nostalgia for sweating copper... but my nerves can’t handle another torch mishap under a cabinet.

Maybe it’s more about the install than the fitting? I’ve seen more leaks from overtightened compression nuts than from push-to-connects that were just snapped on right.

That’s been my experience too. Most of the push-to-connect failures I’ve seen were from pipes not being cut square or not cleaned up - burrs can wreck the seal. If you follow the basics, they hold up fine. I get why people are nervous about them, though. Old habits die hard, and a lot of folks still trust copper and sweat joints more.

I’ve had to fix more leaks from folks cranking down on compression fittings than anything else. People think tighter is better, but it just crushes the ferrule or splits the nut. Push-to-connect is pretty forgiving if you don’t rush it.

Cost-wise, I replaced a kitchen sink setup for a client last month - faucet, supply lines, new trap, and all - came in around $250 in parts with push-to-connects. Labor would’ve doubled that if they hadn’t called me after hours... but at least it was quick and no torch burns on the cabinets this time.

I’ve noticed the same thing with compression fittings - people just crank them down way too hard. I actually messed up my first one because I thought “tighter = better,” but nope, just ended up with a split nut and a slow drip. Push-to-connects felt sketchy at first, but after seeing how they hold up (as long as you deburr and measure right), I’m way less nervous about using them.

Curious if anyone’s tried mixing push-to-connects with PEX for under-sink setups? I’ve only done copper so far, but PEX seems like it could save even more time and money... or am I missing something?

Mixing push-to-connects with PEX under the sink is honestly a game changer. I’ve swapped out copper for PEX in a few rentals, and it’s saved me a ton of time and headaches. The flexibility is great for tight spots, and as long as you use a proper cutter and make sure the ends are clean, leaks are rare. Only thing I’d watch out for is making sure you’re using the right fittings for potable water - some of the cheaper ones out there aren’t rated for it. Otherwise, I’d never go back to all-copper for under-sink stuff unless I had to match existing lines.

- Swapping out copper for PEX was probably the best “unseen” upgrade I’ve done in my kitchen. The cost difference alone is wild - copper prices these days are no joke.
- For my last kitchen sink, I spent about $70 on PEX, push-to-connects, and a cutter (already had the crimp tool from a previous project). That’s less than half what I would’ve paid for copper and sweat fittings, not even counting the time saved.
- Tight spaces under the sink are where PEX really shines. I’ve got a garbage disposal and a water filter crammed in there, so being able to bend the lines around corners without kinking is a lifesaver.
- I do get a little paranoid about leaks, though. Even though, like you said, “as long as you use a proper cutter and make sure the ends are clean, leaks are rare,” I still find myself checking for drips every couple days after a new install. Old habits die hard.
- One thing I’ll push back on: I actually had a push-to-connect fitting fail once because I cheaped out and bought a no-name brand online. Lesson learned - now I stick to SharkBite or Apollo for anything that touches drinking water. The peace of mind is worth the extra few bucks.
- If you’re doing a full sink replacement, don’t forget to factor in the cost of new shutoff valves. Mine were ancient and didn’t close all the way, so that was another $20 or so.

All in, I think my last under-sink job (PEX, push-to-connects, valves) ran me about $90. Not exactly pocket change, but way less than calling a plumber. Plus, I didn’t have to break out the torch and fire extinguisher this time... always a win in my book.

I do get a little paranoid about leaks, though. Even though, like you said, “as long as you use a proper cutter and make sure the ends are clean, leaks are rare,” I still find myself checking for drips every couple days after a new install. Old habits die hard.

That’s not paranoia - it’s just good practice. I’ve seen too many “quick” PEX jobs go sideways because someone rushed the prep or used off-brand fittings. I had a call last year where a push-to-connect fitting popped off under pressure and flooded the cabinet... turns out it was a knockoff brand. Like you said, stick with SharkBite or Apollo and always double-check your cuts. It’s not the cheapest route, but it beats coming back to water damage.

Honestly, I’m the same way - can’t help but check for leaks even when I know I did everything right. It’s just not worth risking a surprise puddle under the sink. Those “quick fixes” always seem to come back and bite you, don’t they?

Yeah, I’m right there with you - paranoia level: expert. Even after triple-checking every connection, I’ll still crawl under the sink with a flashlight like I’m searching for buried treasure. Here’s my process:

- Tighten everything, then stare at it suspiciously for five minutes.
- Run the water and wait for that first drip... which never comes when you’re watching.
- Come back an hour later just to be sure.

I tried one of those “quick fix” kits once - ended up spending more on towels and buckets than if I’d just replaced the whole trap from the start. Lesson learned: shortcuts under the sink are like using duct tape on a leaky boat. Might hold for a bit, but you’ll regret it at 2am when you hear the drip-drip-drip.

Honestly, I’d rather spend a little extra upfront than deal with soggy cabinets and mystery smells down the line.

I totally get the flashlight routine - my last plumbing project had me under there for what felt like hours, just waiting for a single drop to betray me. I’m with you on skipping the “quick fix” kits. I tried one of those flex pipe things because it looked easy, but it never sealed right and I ended up with a slow leak that warped the cabinet floor. Not worth the hassle.

When I replaced my kitchen sink drain, I went step-by-step: measured twice, bought all new washers and a decent P-trap, and even used plumber’s putty instead of relying on those pre-installed gaskets. It cost a bit more upfront (maybe $40-50 in parts), but no leaks so far.

Curious - did you go with PVC or metal for your trap? I debated for ages and finally settled on PVC since it’s easier to work with, but I keep hearing mixed opinions about longevity.

I hear you on the flex pipes - tried one once, never again. Ended up with a puddle under the sink and a lot of cursing. For my last job, I went with PVC too. Here’s what I found:

- Way easier to cut and fit, especially in tight spaces.
- No rust worries, but I’ve heard some folks say the threads can strip if you overtighten.
- Metal looks nicer, but honestly, once it’s under the sink, who cares?

Spent about $35 on all the parts. No leaks so far, fingers crossed. I think as long as you don’t cheap out on the washers and take your time, PVC holds up just fine.

Ever try getting that last PVC joint to line up when you’re wedged under the sink? Feels like a game of Twister for plumbers. Curious - did you use the slip-joint washers or those rubber gaskets? I swear, the wrong gasket and you’re mopping up for days...

Feels like a game of Twister for plumbers.

That’s the truth. Last time I did mine, I ended up half inside the cabinet, flashlight in my mouth, trying to keep the new trap from spinning. I went with slip-joint washers - less plastic waste than those thick rubber gaskets, and honestly, they seem to seal better if you’re careful. Ever notice how some brands use way more packaging than others? Drives me nuts. Did anyone try those “eco” PVC pipes that claim to be recyclable? Curious if they’re worth the extra bucks or just greenwashing...

Haha, I know that cabinet yoga all too well. It’s like the universe’s way of reminding me I’m not as flexible as I thought. I totally get what you mean about packaging - some brands really go overboard, like I need a separate trash bag just for the wrappers and spacers. The slip-joint washers are a good call. I tried them last time and didn’t have any leaks, which felt like a small miracle.

I’ve seen those “eco” PVC pipes at the hardware store, but I’m always a bit skeptical. The labels say recyclable, but then you read the fine print and it’s like, “only in facilities that accept #7 plastics,” which around here is basically nowhere. Still, I’d rather pay a little more if it actually means less junk in the landfill. Hard to tell if it’s legit or just marketing fluff though.

Last time I replaced my sink trap, I tried to reuse as much of the old piping as possible. My partner laughed at me for scrubbing out old PVC elbows, but hey - less waste, right? It’s weird how you start noticing all this stuff once you try to be a bit more eco-conscious. Even the tiniest things, like those little plastic bags with screws in them... they add up.

Anyway, props for tackling it yourself and thinking about the waste side of things. Most folks just want it done fast and don’t think twice about tossing all the old parts. If you ever figure out which brands are actually walking the walk on recyclability, let us know. Until then, guess we’ll keep doing cabinet gymnastics and hoping for fewer leaks...

That’s a good point - once you start paying attention, the waste really stands out. I’ve noticed some brands are moving to cardboard or compostable packaging for fittings, but it’s not widespread yet. On the “eco” PVC, I share your skepticism. Most municipal recycling streams don’t handle #7 plastics, so even if it’s technically recyclable, it rarely happens in practice. Sometimes reusing old elbows or traps is actually the greener move, even if it means a bit of extra scrubbing and time under the sink. Funny how “doing it right” often means more work and less convenience.

I get what you’re saying about reusing old traps and elbows, but I’m always a bit wary of that, especially if the fittings are showing any signs of wear or corrosion. I’ve seen a few leaks pop up months later because someone tried to save a part that really should’ve been replaced. Sometimes the greener move is just making sure you don’t have to rip everything out again down the road. That said, I do keep a bin of old hardware for those oddball situations where nothing else fits... just gotta know when to let go.

Couldn’t agree more. I’ve seen too many “savings” turn into headaches when reused parts fail. I’ll keep oddball bits too, but if there’s any rust or pitting, it’s not worth the risk. A few bucks now beats a flooded cabinet later.

Couldn’t have said it better. I’ve seen folks try to save a few bucks by reusing old traps or washers, only to end up with a soggy mess under the sink a month later. Sometimes it’s just not worth the gamble. I always tell people - if it looks sketchy, it probably is. Spend a little more now, save yourself the mop and bucket routine later.
