Is a Backflow Preventer a Check Valve? How to Choose Between Fast Fix and Right Fix on Everbilt Parts

I coordinate emergency parts orders for contractors. When a pump dies on a Saturday morning, or a sliding door comes off its track two hours before a final walkthrough, I'm the one figuring out which part gets there fastest.

Nine years, 200+ rush orders, and roughly 95% on-time delivery later, I've noticed something: most emergency calls trace back to the same mistake. Someone chose the fast fix instead of the right fix.

This guide compares those two approaches across five common Everbilt decisions. I'm not going to tell you the fast fix is always wrong—sometimes it's the correct call. But I am going to show you how to calculate the total cost before you decide.

Is a Backflow Preventer a Check Valve? No—and the Confusion Is Expensive

The most common question I get from contractors is: "Is a backflow preventer a check valve?"

Straight answer: No. They're related, but they do different jobs.

A check valve is a one-way valve. Water flows in one direction, and the valve closes if it tries to flow backward. A backflow preventer is a complete assembly that includes check valves plus a relief valve—it's designed to keep non-potable water from contaminating the drinking supply, not just to control flow direction.

Why does this matter for your wallet?

• Check valve: $15–$40, single function
• Backflow preventer: $80–$250, code-compliant for cross-connection protection
• Failed inspection due to wrong part: $300–$800 in rework labor, plus the correct part

FTC advertising guidelines require claims to be truthful and substantiated (ftc.gov), and the same logic applies to your installation: if you claim something is a backflow preventer when it's just a check valve, you're setting yourself up for liability. I've seen a $25 shortcut turn into a failed commercial inspection and a $1,200 emergency correction. (Should mention: that contractor now calls me before buying any valve rated below 1 inch. Live and learn.)

Everbilt 1/2 HP Shallow Well Jet Pump: Repair or Replace?

The Everbilt 1/2 HP shallow well jet pump is a workhorse. It handles wells up to 25 feet deep and typically sells for $150–$180 at Home Depot. When it fails, I get the same question: "Should I rebuild it or buy a new one?"

Here's the framework I use:

Repair if the pump is under 5 years old and the problem is a leaky seal or clogged impeller. Repair parts run $20–$30, and with the manual in front of you, the fix takes about 2 hours.

Replace if the motor is burned out, or the pump is older than 5 years and repairs would cost more than 50% of a replacement.

I want to say 60% of contractors I talk to try a motor replacement first, but don't quote me on that number—the point is the math is usually against them. A new Everbilt 1/2 HP shallow well jet pump includes a fresh warranty, new seals, and a new impeller. Rebuilding a 7-year-old pump is like putting a new transmission in a car with 200,000 miles. Sometimes it makes sense. Usually, it doesn't.

One more thing: check the pump's model number before ordering any part. Everbilt made design changes over the years, and the wrong impeller kit turns a 2-hour repair into a 3-day saga. (Not that I have personal experience with that. Okay, I do.)

Everbilt Sliding Door Hardware Instructions: Use Them or Pay the Price

In March 2024, 36 hours before a client's final walkthrough, a contractor called me in full crisis mode. His crew had "temporarily" fixed a pocket door with a coat hanger six months earlier. That coat hanger finally gave out, and the door was lying half in the wall, half in the doorway.

It was a mess. And here's what made it worse—the Everbilt sliding door hardware instructions were in the box the whole time.

The fast fix approach: bend another wire, wedge it, and hope the door stays on the track through the walkthrough. That costs you 20 minutes now, but it's a ticking time bomb. The inspector opens and closes the door ten times during a final walkthrough, and it jams. The client won't sign, the schedule slips, and you're back on-site next week.

The right fix approach: install the Everbilt sliding door hardware kit properly. It's $35–$60 for the track and rollers, and the instructions cover the whole job in about 15 minutes of reading. Total labor: 2–3 hours. The adjustment screws included in the kit are what make the door slide smoothly, and there's no way to replicate that with a coat hanger.

The Everbilt sliding door hardware instructions are available on Home Depot's website if you've lost the paper copy. The roller adjustment section alone is worth the lookup. (Which, honestly, should be obvious. But I've seen enough contractors eyeball it to know it isn't.)

Ladder Trestle Brackets: The One Place I Won't Compromise

Ladder trestle brackets let you turn two ladders and a plank into a stable work platform. They're simple, low-tech, and easy to underrate.

I have mixed feelings about this category. On one hand, Everbilt's trestle brackets only cost around $15–$20 a pair. On the other hand, I've seen contractors build improvised supports from 2x4s and drywall screws because they didn't want to spend the money.

The surprise isn't that rated brackets are worth the $20. The surprise is how many people don't check the load rating before they climb. Everbilt's brackets list their capacity right on the product page. It takes 30 seconds to verify the rating.

The fast fix here isn't even a fix—it's gambling with your safety. A fall from even 6 feet costs way more than a pair of rated brackets. Workers' comp claims, lost jobsite time, liability. I can't put an exact number on it, but I can tell you the $15 savings on brackets is the worst trade in this entire article.

Use the rated brackets. Check the capacity. And don't let anyone on your crew talk you out of the extra $10. (Surprise, surprise, the guy who "doesn't need instructions" is usually the first one who can't figure out why his scaffold wobbles.)

Electronics Pocket Screwdriver: A $5 Lesson in Total Cost

The Everbilt electronics pocket screwdriver is about the smallest thing I ship. It's under $5, it folds up like an old-school pocket knife, and it has interchangeable bits for electronics, faceplates, and small appliance screws.

I include it in this comparison because it's the cleanest example of total cost thinking.

The "I'll just use my multitool" approach: is free, assuming you own a multitool. But flipping out the screwdriver blade, finding the right angle, and being careful not to strip a #1 Phillips screw takes 3–4 times as long as using a dedicated driver. At a billable rate of $75–$100 an hour, that's not free at all.

The pocket screwdriver approach: $5, fits on a keychain, and has the right bit for the job already swapped in.

If I remember correctly, I've watched a master electrician strip two screws trying to use a multi-bit driver that was too long for the faceplate. The pocket screwdriver handled it in 30 seconds. Total cost comparison: $5 versus the price of re-tapping a stripped hole on someone's new kitchen island.

Low-stakes example, but it proves the point: the cheapest tool is the one you can finish the job with.

The Framework: When to Choose the Fast Fix vs. the Right Fix

In my first year doing this, the numbers said the cheapest part was the right call. My gut said otherwise. I ordered the cheap part anyway, and it failed on a job site two weeks later. Since then, every cost analysis I've run points to the same conclusion: total cost includes the price of failing twice.

Here's the simple guide I give contractors:

Choose the fast fix when:

• It's genuinely temporary (e.g., a 48-hour patch to get through a scheduled maintenance window)
• The repair costs less than 50% of replacement
• No safety systems or code compliance are involved

Choose the right fix when:

• Code requires a specific device (backflow preventer vs. check valve)
• Failure causes secondary damage (a worn pump that floods a basement)
• Height or load-bearing safety is involved (trestle brackets)
• You won't be the one doing the job again in six months

One last thought on shipping. I've had contractors agonize over a $10 difference in part price, then pay $30 in expedited shipping because they ordered the wrong item. For small parts, USPS First-Class Mail large envelopes start at $1.50 (usps.com, rates effective January 2025) and usually arrive in 2–3 days. The right part, with enough time to ship standard, is cheaper than the wrong part shipped overnight 100% of the time.

That's the total cost framework in a nutshell: the cheapest solution is the one that works, doesn't fail, and doesn't need to be redone. I've learned that lesson 200-plus times, and it gets more expensive every time I forget it.
