Hardened Cooking Grease
Grease poured down warm, then cooled and hardened inside the trap and branch line. This is the number one cause of kitchen sink clogs, and it's why hot water and chemicals rarely fix it. The plug has to be physically removed.

Kitchen sink full of water that won't go down, or a bathroom sink draining slower every week. We clear it and tell you why it clogged in the first place.

A clogged sink that's already full of standing water and won't drain no matter what you pour down it is the point where a plunger and a bottle of drain cleaner stop helping, and it's one of the most common calls Max Plumbing LLC runs across Peoria and the West Valley. Here's what we do differently: instead of blasting a chemical down the line and hoping, we open the P-trap under the cabinet first to see what's actually caught there, then decide whether it's a two-minute trap cleanout or a clog sitting deeper in the branch drain that needs a machine. Chase Rudders owns and runs this company out of Peoria, so a licensed AZ plumber picks up the phone, not a dispatcher. Call (480) 353-8080 and we'll get someone to you.
A slow sink is easy to ignore until the day it stops draining entirely, usually mid-dishwashing with a sink full of greasy water. Most single-fixture sink clogs we clear in one visit. What tells us it's bigger is when both basins of a kitchen sink back up at once, when clearing the trap does nothing because the blockage is downstream, or when the same sink re-clogs within weeks. Those point to a deeper drain-line problem, not the trap. We show you exactly what we find before recommending anything past a clearing.

plumber clearing a clogged kitchen sink drain under the cabinet in a Peoria, AZ home
A plumber for a clogged sink starts under the cabinet, not at the drain opening. The P-trap is that U-shaped pipe below the basin, and it's where the vast majority of kitchen and bathroom sink clogs actually sit: grease that cooled and hardened, coffee grounds, hair bound up with soap scum. We put a bucket under it, unthread the trap, and clear it by hand. That alone solves a large share of the sink calls we run.
If the trap is clear but the sink still won't drain, the clog is past it in the branch line. That's when we run a hand auger or a drain machine through the trap arm to reach it, typically 5 to 15 feet in. We don't pour store-bought chemical openers down a sink. They pool in the standing water, generate heat against the trap seals and the finish on your basin, and rarely reach a real grease clog anyway. Call (480) 353-8080 and we'll clear it the right way the first time.
drain cable run through the trap arm to clear a clogged sink branch line in the West Valley
A kitchen sink that's clogged and won't drain is almost always a grease-and-food problem in the trap or the branch line, not the drain opening you're staring at. Grease is the big one: it goes down warm and liquid, then cools and coats the inside of the pipe like candle wax, catching everything after it. On homes with a garbage disposal, starchy and fibrous scraps (potato peels, celery, coffee grounds, pasta) make it worse by binding to that grease layer.
Here's the honest sequence we work through on a kitchen sink:
"If pouring boiling water and a bottle of drain cleaner didn't move it, the clog isn't at the surface. It's a grease plug down in the line, and that needs a cable, not another chemical."
We clear the immediate blockage and tell you straight whether it's a one-off or a pipe that's going to keep doing this. Ready when you are: (480) 353-8080.
bathroom sink with a slow-draining pop-up stopper serviced by a Peoria plumber
A bathroom sink draining slow is a different animal from a kitchen clog. It's rarely grease. It's hair bound together with soap scum and toothpaste, wrapped around the pop-up stopper assembly and the top of the trap. It builds gradually, which is why the sink gets slower and slower over months instead of stopping all at once.
The first thing to check is the pop-up stopper itself. Pull it up and out (many lift straight out, some need the pivot rod behind the drain loosened first) and you'll usually find a slug of hair and gunk wrapped around the base. Clearing that alone brings a lot of slow bathroom sinks right back to full speed.
If the stopper is clean and it's still slow, the buildup is deeper in the trap or the drain is partly blocked by hardened mineral scale narrowing the pipe. We clear the trap, and if the whole bathroom group (sink, tub, and toilet) is sluggish together, that points to the shared branch or vent, which is a bigger diagnosis we'll walk you through before doing anything.

Not every slow sink is worth paying a plumber for yet, and we'll tell you that on the phone. If a single bathroom sink is draining slow, pull the pop-up stopper and clear the hair off it first. That's a five-minute job you can do yourself, and it fixes a lot of slow sinks outright. For a kitchen sink, if the disposal side is the only one backed up and the unit hums, hit the reset button on the bottom of the disposal and try clearing it with the disposal wrench before calling anyone.
Don't call us if the sink drains fine and you're just doing preventive maintenance, or if a single bathroom sink slowed down and you haven't cleaned the stopper yet. You may not need us at all.
Call us when both kitchen basins are full of standing water that won't drain, when clearing the trap and stopper did nothing, when the sink backs up every time the dishwasher runs, when water comes up in a second fixture, or when the same sink has re-clogged three or more times this year. Those are the situations where DIY stops working and waiting turns a clearing into a pipe repair.

We work throughout the greater Phoenix Valley and we're based right here in Peoria, from the established neighborhoods near 83rd Avenue and Olive to the newer builds out past Lake Pleasant Parkway. A clogged sink repair in Peoria, AZ shouldn't mean a truck dispatching from the far side of the metro, and ours doesn't. If you're in Glendale, Sun City, Buckeye, or Litchfield Park, we're already running your area. If the clog turns out to be deeper than the sink, our full drain cleaning service handles the branch and main lines, and since the cabinet's already open, we can swap a corroded sink faucet or supply valve in the same visit.
