Apollo Valves Buying Checklist: 8 Steps Before You Order or Install

Who This Checklist Is For

8 years handling valve and fitting orders. I have personally made — and documented — 11 significant mistakes, totaling roughly $4,800 in wasted budget. Now I maintain our team's pre-order checklist.

This one is for distributors, contractors, and installers buying Apollo valves and pipe fittings through online channels who want to catch problems before the box is open. It covers the whole run, from spec to commissioning. Eight steps. You can skip any of them. The cost just comes back later.

I was the guy who got it wrong in year one (2017). That is why this list is a little long.

The 8-Step Checklist

1. Lock the system parameters before you look at a single part number

Size, pressure rating, temperature range, media, connection type. Write them down first. Then go shopping.

Most returns are decided right here. In 2020 I sent over an order that said standard 3/4 size. The supplier heard standard. Same two words, completely different meaning on the other end. The order arrived and nothing matched the pipe we had on site. $2,100 in parts, six days of rework.

One more thing that still bites people: nominal pipe size is not the same as the actual bore. Put both numbers on the sheet.

2. Match the valve type to the function, not the other way around

Gate valve = isolation. Ball valve = quick on/off or rough throttling. Check valve = backflow prevention. Relief valve = pressure safety. Backflow preventer = code-required cross-connection protection.

And then there is the question I get almost every week: can you throttle a gate valve?

Technically, yeah. You turn the stem halfway and flow drops.

Real answer: no. A wedge disc hanging in the flow path chatters, erodes the seating surfaces, and you end up with a valve that won't seal fully or modulate reliably. You won't see it on commissioning day. You'll see it three months in when the valve is stuck and passing. Use a globe or ball valve for throttling, or a purpose-built control valve if it's an actual control loop. The difference is a few dollars and one call-out.

3. Verify the certification, not the brand

“It's made by Apollo” and “it's compliant for your system” are two different statements. People mix them up constantly.

For anything touching potable water, NSF/ANSI 61 certification is the bar — that standard covers the health effects of components in drinking water systems. Backflow assemblies carry ASSE listings, and separate states layer their own plumbing code requirements on top. Check the specific model, not the manufacturer name. The certificate should name the model number.

Where this bit me: a 2021 print called for a backflow preventer. I bought the one that looked right. The AHJ wanted a specific listing I hadn't verified. Return freight plus reorder plus four days of schedule: $340.

4. Read the part number character by character

This is the expensive one.

September 2022. We placed a batch order that included a Flex series water-powered back-up sump pump — 540-0005 territory. In that family, a single suffix character separates one connection configuration from another. I checked the prefix, assumed the rest matched what I'd bought before, and moved on. Three units arrived with the wrong connections.

$640 in rework and freight. A one-week delay on the client's side.

My rule since then: pull the part number off the original spec sheet, paste it, and compare it character by character. Then have a second person do it again. Sounds excessive. It has caught me twice since.

5. Buy the channel, not just the price

This is where Apollo valves online gets tricky. You're buying a component with a manufacturer behind it.

The Apollo limited warranty is set per product line, and it generally expects proof of purchase from an authorized source. Buying from a random marketplace seller doesn't make the valve bad. It makes your claim harder if you ever need one.

Look, I'm not going to tell you the cheapest listing is always wrong. I'm telling you cheap and inexpensive are different things. On a valve, the spread is usually a few bucks. The saved money doesn't stretch far when something goes sideways.

Since we moved our recurring items to our distributor's order portal, turnaround went from five days to two. No magic to it — the order drops straight into their system and nobody re-types it. That alone saves us hours a month.

6. File the paperwork the moment you order

Invoice, packaging photos, the warranty text that came in the box. All of it goes in a folder named after the project, not the order date.

It took me three years and about 200 orders to understand that a warranty claim isn't won by being right. It's won by having the record.

Between you and me, this step felt like pure admin overhead for two years. Then I needed it and had everything in one place in under ten minutes. That's the whole argument.

7. Install-day checks — including the anchoring nobody thinks about

Here's the step most people skip: support and anchoring.

A 4-inch valve on a hot line has real weight. Let the pipe carry it alone and you get cracked bodies and weeping flanges. ASME B31.9 puts limits on what building services piping can take on its own, and there's a reason valves near anchors get their own support. Pipe anchoring and hangers around the valve aren't optional extras — they're the load path.

While you're down there, run the rest of the install check:

• Flow direction. There's an arrow on the check valve. It means something.
• Torque on threaded and flanged joints. Over-tight is as bad as under-tight.
• Gasket material matches the media and the temperature.
• Handle clearance on ball and gate valves — leave room to turn it fully.

8. Commission it, then write it down

Record the model number, install date, and initial pressure test result. Put it in the same project folder. Next time there's a service call, you're not guessing.

This is the gap between what I understood in 2017 and what I actually accepted years later. Documentation looks slow. Not having it is what actually runs slow.

Where I Still Slip (and You Might Too)

This list doesn't stop me from making mistakes. It stops me from making the same ones twice.

• Throttling a gate valve. Still the number one question I get. Still a no.
• Assuming the Apollo name covers the certification. It doesn't. Verify by model.
• Ordering off a size number alone. Nominal size and actual bore are not the same figure.
• Treating a marketplace listing as warranty proof. It isn't. The authorized invoice is.
• Skipping post-commissioning records. Somebody will find the problem eventually. Just don't let it be five years from now.

The most expensive mistakes I've seen were never about price. They were unchecked assumptions. That's what the list is for.
