What people told us
$180
That's the plumber quote people wrote down again and again. Half of the 123 quotes in the comments landed between $100 and $350. For a drip. For a slow drain. For a toilet that runs.
Source: 16,000 viewer comments on 48 home-plumbing videos, read one by one in 2026.A viewer wrote that a plumber quoted $500 to fix a shower that kept pouring out of the tub spout. The part cost $7 at the hardware store and took under five minutes.
Another wrote that the plumber wanted $150 just to come out and look at a running toilet.
One wrote that a plumber wanted $1,400 from her mother for a tub spout. It took twenty minutes and cost nothing.
And under all those numbers, the same few sentences, over and over. I'm a widow. I'm a single mom. I'm 69 and I've never done this. I don't have a dad to show me.
That's the part Lenny can fix.
The receipt
Every fix in the book comes with the price a plumber in a US city charges for that visit, and what the parts cost you. Here are its five parts added up, one line each.
The plumber column is $37,814. Your column is $244 in parts, for all 200 fixes.
Typical 2026 plumber prices in a US city, taken from each book's own price table. Your town is a little higher or a little lower.
This is for you if…
I'm on my own now. There's nobody to call.
That's who Lenny wrote for. Every fix starts with where to turn the water off, then one step at a time with a picture, in plain words. No word you have to look up.
I've never held a wrench in my life.
145 of the 200 fixes need no new part at all: you clean it, lift it, turn it a quarter turn. The rest use a part under $10, and the page tells you what to ask for at the store.
I'm scared I'll make it worse.
Every page has "The usual mistake" so you don't make it, and "Call a plumber when" so you know where your job ends and his begins. Water off first, every time.
I stood in the store and didn't know which one to buy.
Take the old part in a plastic bag. Every fix that needs a part tells you what to ask for at the hardware store, so you buy it once.
I don't know when it's really time to call.
Before You Call a Plumber gives you the fair price list for 2026, the questions to ask on the phone, and the five red flags to send someone away.
I rent, and I don't want trouble with the landlord.
Cleaning, tightening and adjusting what's already there changes nothing in the apartment. Before you swap a part, ask the landlord first, and now you can tell him exactly what's wrong.
A letter from Lenny
I'm Lenny Kowalski. I started plumbing on the South Side of Chicago in 1980. Forty-five years later I've been under more sinks than I can count, and what stays with me isn't a pipe. It's the look on people's faces when I hand them a bill for a five-minute job and two dollars in parts.
A chain that slipped off. A little rubber washer. A clog sitting three inches below the drain. A red button on the bottom of the garbage disposal that nobody ever showed them.
This book is what I'd show you if I lived next door. Every fix costs you under $10 in parts, or nothing. Every one tells you what a plumber charges for the same job, and every one tells you when it's time to put the wrench down and call somebody.
You don't need to be handy. You don't need a garage full of tools. If you can turn a knob and read a page, you can do this. And nobody here is going to make you feel dumb for asking.
— Lenny

Your order
A plumber charges $150 just to come out and look at a running toilet. The whole book, 380 pages and 200 fixes, is $39.99, and it stays on your computer and your shelf for good.
Running, clogged, weak, leaking or wobbling. The chain, the $6 flapper, the plunger done right, and the 2-minute check for the main sewer line.
Kitchen, bathroom, shower and tub. Lenny's cup, the trap in 5 minutes, the old cast-iron house, and the 30-second Sunday routine.
Dripping faucets, weak showers, the tub spout that won't switch over, squealing handles, and how to buy the right part on the first trip.
Sewer smells, the garbage disposal and its red button, hidden leaks, and the water bill that keeps climbing.
The first ten minutes of an emergency, a Chicago winter, the water heater, and the fair price list so nobody overcharges you.

Questions
That's exactly who it's written for. 145 of the 200 fixes need nothing you have to buy: you clean something, lift something, or turn it a quarter turn. Every fix says what you need, how long it takes, and the steps one at a time with a picture. The book starts with the 8 words you need, explained like a neighbor would.
Every fix starts with the water off, so nothing sprays. Every page has "The usual mistake," so you skip it, and "Call a plumber when," so you know where your job ends. When the page says call, you call, and you tell the plumber what you already checked. That saves his time and your money.
It won't, because the first step of every fix is the shutoff valve. Part 5 opens with finding your main valve and hanging a tag on it, today, while nothing is wrong. Ten seconds to close it when you know where it is.
Take the old part to the store in a plastic bag. Every fix that needs a part tells you what to ask for at the hardware store. Part 3, The $7 Shower Fix, has a whole page on buying the right part on the first trip.
Every one of the 200 fixes ends with "Call a plumber when." Gas, electricity and the main sewer line are always a job for a licensed professional. And Part 5, Before You Call a Plumber, gives you the fair price list for 2026 and the questions to ask on the phone, so the call costs what it should.
Lenny has worked in bungalows and two-flats from the 1920s since 1980. Part 2 has a page on going gentle with cast-iron drains, and Part 1 shows the 2-minute check for the old clay sewer line. No chemical drain cleaners in old pipes, ever: hot tap water and your hands do the job.
No. Not one fix in the book uses a chemical drain cleaner. Part 2 has a page on why Lenny never pours them: they eat old pipes along with the clog, and when they don't work, they sit in your sink and make plunging dangerous.
Cleaning, tightening and adjusting what's already there changes nothing in the apartment. Before you swap a part, ask your landlord. Either way, you'll know exactly what's wrong when you call.
No. It's one PDF file, so you have it the minute you pay. They print well at home on ordinary paper, and you can read them on a phone, a tablet or a computer. Print the pages you need and keep them under the sink.
Instantly, by email. You pay on Hotmart's secure checkout, and Hotmart sends the book to the email you typed, right away. Check your spam folder if you don't see it in a few minutes, or write to bagasystudio@gmail.com and we send it again.
Because a leak doesn't care which book it's in. One book, one contents page, every fix numbered 1 to 200, so you look up what's wrong and you're on the right page in seconds. It's all of Lenny's books in one, nothing left out.
You have thirty days. Ask for a refund through Hotmart, or write to bagasystudio@gmail.com, and you get every cent back. No reason needed.
Payments go through Hotmart on an encrypted page; we never see your card number. You pay once. There is no subscription and nothing that renews.
P.S.Tonight, while nothing is wrong, find the valve behind your toilet and turn it to the right until it stops. Then open it again. That's how every fix in this book starts, and it's the difference between a small job and a wet floor. There are 200 more fixes where that came from, and the first plumber visit you skip pays for the book.
