Here is the short answer before you spend your time on the whole story: If you do plumbing work more than once a month, keep a RIDGID 8 pipe wrench in your bag for small accessible fittings, buy a RIDGID basin wrench before you touch a faucet, own a strap-style filter wrench, and don't buy a nail gun just because the Lowe's nail gun display is on sale. And if you are going to grind stainless steel, use a clean wheel made for stainless, not whatever happens to be sitting on your bench.
I learned those lessons the expensive way. The mistakes in this article cost me roughly $700 in parts, rework labor, and tool purchases that made sense only inside my own head. Maybe $750 - I would have to check the spreadsheet. The exact number doesn't matter. What matters is that one cheap decision led to two or three expensive ones.
For context: I've handled plumbing repair and light remodel work for about eight years, first as a maintenance handyman and then as the owner of a one-person service company. I'm the guy who shows up, and I have personally documented far more mistakes than I'd like to admit. This isn't a brand review. It's a record of what those mistakes taught me about total cost.
RIDGID 8 Pipe Wrench: Know What It Can't Do
The RIDGID 8 pipe wrench is a great second wrench. It fits in a standard tool bag, and it's ideal for accessible 1/2-inch and 3/4-inch fittings that aren't corroded. My grab sequence now goes: use an 18-inch first for anything stubborn, then reach for the 8-inch when the work is smaller or the space is tight.
That order is the opposite of what I did in 2018. I was replacing a hose bib that had been on the house long enough to become part of the structure. I soaked it, waited, put my RIDGID 8 pipe wrench on the flat of the valve, and leaned into it with more enthusiasm than brains. The wrench slipped, my knuckles found the brick wall, and the hose bib didn't budge.
I ended up opening drywall inside the house so I could cut the pipe out and start fresh. What should have been a quick outside repair turned into a two-visit project with drywall mud involved. Looking back, I should have started with an 18-inch wrench. The 8-inch version wasn't the wrong tool because it was cheap. It was the wrong tool because it didn't have enough handle length to keep steady torque on a seized fitting.
That's the part most people don't realize: the difference between wrench sizes isn't mainly reach, it's leverage. An 8-inch pipe wrench has to be pulled at a weird angle when you're working low to the ground. The longer wrench lets you keep your body behind the jaw and apply force in a straight line. That feels safer, and it is safer.
I still carry the 8-inch RIDGID every day. It does supply stops, fixture nuts, and light plumbing calls beautifully. I just don't ask it to do work that needs a longer handle. At least, not anymore.
RIDGID Basin Wrench: Buy It Before You're Under the Sink
The basin wrench lesson came next. I had put off buying one because it looked like a single-purpose tool, and I didn't like single-purpose tools. I thought I could make do with the wrenches already in my van. That thought cost me an afternoon.
In 2020, I was replacing a leaking faucet in a rental unit. The mounting nuts for an old faucet sit up inside the sink deck, behind the bowl, where your eyes cannot go. There wasn't enough room for my hands, let alone a normal wrench. I tried an adjustable wrench, I tried a small pipe wrench inverted, and I tried language that I won't repeat here. None of it worked.
The next morning I bought a RIDGID basin wrench. The long shaft reaches up behind the sink, the spring-loaded jaw grabs the nut, and the T-handle at the bottom lets you turn it from a position where you actually have room. The old faucet was out in about twenty minutes. That tool has paid for itself many times over since.
My only regret is that I didn't buy it with the pipe wrench. At least, that's been my experience with residential work; I understand commercial sinks can be different.
Filter Wrench: Get a Strap Style Before You Need One
A filter wrench sounds like the kind of tool you can buy later. Then later arrives, usually on a Saturday evening, and a plastic filter housing will not come off.
Most whole-house water filter housings have lugs on the outside for a filter wrench, and a lot of them are made of plastic. A pipe wrench or channel-lock pliers can crush or crack those lugs. That turns a simple filter change into a flooded cabinet and a new housing.
What you want is a strap-style filter wrench, the kind that wraps around the housing and squeezes evenly. I carry a RIDGID strap wrench for that job, not a dedicated plastic tool with prongs. The strap grips without teeth, so it doesn't damage the housing when you have to lean on it.
Don't wait until the housing is already leaking or stuck to shop for this. Buy it before, throw it in the drawer, and forget about it until you need it. That is the total cost way to buy any tool: the cheap version is only cheap if it works the first time.
Don't Let the Lowe's Nail Gun Aisle Make the Decision
The nail gun mistake almost happened in 2024, and it wasn't even a tool mistake at first. A client asked me to install a shiplap accent wall in a laundry room while I was already there fixing a supply line. A wall like that needs a nail gun, and I didn't own one.
I stopped at the big-box store to pick up fittings and walked past the Lowe's nail gun display. There was a cordless brad nailer bundled with a battery for right around $199. It seemed like a good deal. I stood there and started doing mental math, and that's when the old version of me and the new version of me had a conversation.
The job was one day of work. The nail gun would sit in my van for months afterward. Once a year, maybe twice, the tool would come out of storage. Rental cost for a decent nailer from a local shop was $35 for a Saturday. I saved $164, and I didn't add another battery platform to my collection.
Look, if you're going to use a nail gun every week, buy one. Buy a good one, use it, and stop worrying about the price tag. And if that good one happens to be a RIDGID power tool, register it after purchase; the service agreement only works for registered tools. But if you're about to buy a nail gun for a single project, run the math the same way you would for a quote: total cost, not sticker price. Buying tools for the person you wish you were, instead of the work you actually do, is how van shelves fill up with expensive dust collectors.
What Type of Grinding Wheel Is Best for Stainless Steel?
Short answer: a clean wheel labeled for stainless steel, usually zirconia alumina or ceramic alumina grain, used only on stainless. For an angle grinder, that usually means a Type 27 depressed-center wheel or a flap disc with a stainless steel label. If you see the word INOX on the package, that's the stainless version too.
The first rule is separation. Don't use the same wheel for carbon steel and stainless steel. I found this out the hard way in 2022 while cleaning up stainless mounting brackets that I had cut for a commercial hand dryer. I grabbed a worn grinding wheel from my regular pile, made the edges look perfect, and went home satisfied. The next morning those edges had orange spots.
The spots weren't the stainless rusting by itself. The old wheel had carbon steel embedded in it, and that embedded steel transferred onto the stainless surface and rusted. I had to go back over everything with a fresh stainless flap disc and then polish the marks out. The job took an extra forty-five minutes because I tried to save myself a trip to the tool store.
Heat is the other enemy. Stainless doesn't need brutal pressure; it needs a cool cut. Zirconia and ceramic abrasives run cooler and resist loading better than basic aluminum oxide. They cost a little more, and for stainless they're worth it.
So if someone asks me what type of grinding wheel is best for stainless steel, my answer is simple: use a stainless-labeled wheel, use it only on stainless, and let the abrasive do the work. The price of a dedicated wheel is a lot smaller than the cost of explaining rusty spots on a supposedly stainless finish.
When to Ignore This Advice
Total cost thinking has an exception: frequency. If you're a homeowner doing one faucet replacement, you don't need a professional-grade basin wrench. If you cut stainless once a year, a cheap dedicated wheel might be enough. If you frame houses every week, rent-versus-buy decisions look different.
I'm not saying every tool must be the most expensive version. I'm saying the purchase price is only one line in the calculation. Trips back to the store, time wasted, parts damaged, and the cost of doing the job twice are all part of the real price. Use that frame, and you'll make better decisions than I did.
The most expensive tool I own is not the one I paid the most for. It's the one I bought because I didn't want to buy the right one. That $40 compromise ended up costing several hundred dollars and a patch of drywall. The RIDGID 8 pipe wrench is still in my bag, but now it knows its place.
