Femco Drain Valve did work on the 12.5 KW Onan

[brobox]

After trying the Fumoto Drain valve on the 12.5 Onan that would not fit the skid plate opening, the Femco Valve did fit with plenty of clearance. Twice the price of the Fumoto, but at least it fits for those that change their own generator oil. The part # for the Kuboto engine D-1503 is a 10-22150-11 plus the drainer. Femco: Eliminate Messy Oil Changes - No-Spillâ„¢ Systems

The Femco comes with a nice adjustable round container to keep your old drain plug and the drainer for the Femco valve in your tool box. I did remove the hose from the drainer so I can drain the oil directly into old oil or milk jugs.

Yeah, no more messy oil changes and a savings of about $200. for taking it in for an oil change.

Chuck, thanks for your efforts in helping to determine which quick drain valve will work on the generator. I will be installing this on the next oil change. The picture shows it to be an excellent choice for the application.

Bill, thank you for your help. The valve looks like it will work fine. There is a lot more ground clearance on the location of this generator over the Travel Supreme making changing the oil much easier. The filter has a nice drain built in and drains into a water of soda bottle perfectly.

I tried to call you back yesterday, but missed you.

I’m resurrecting this older thread to ask a question of Chuck or anyone else who may wish to chime in.

I’m about to order a Femco drain valve for the Onan 12.5K generator in our 2018 Cornerstone. Checking the Femco web site, I was able to identify two options:

Standard Drain Valve, Part #10-22150-11, Item #6090020047:

https://www.femco.com/standard-lb-6090020047-m22x15-t10-8-4

Compact Drain Valve, Part #15-22150-06, Item #7090020195:

https://www.femco.com/compact-lb-7090020195-m22-x-1-5-t10

The two valves are fundamentally the same, but the Compact valve is designed to not protrude as far down, with the difference being 20 millimeters or a tick over three-quarters of an inch.

For whatever reason, the Compact valve is priced lower - $30.36 versus $39.95 for the Standard valve, but that’s not a major consideration.

Looking at the underside of the generator in our 2018 Cornerstone and running the slide tray in & out, I don’t see any potential clearance issues if I select the Standard drain valve, but I thought I’d pose the “Standard versus Compact” question here before moving forward.

The first three images below relate to the Standard drain valve, while the remaining three relate to the Compact drain valve.

Thanks in advance for any & all insights and recommendations!

Femco also makes a valve for the Cummins 450 ISL.
If you change your own engine oil this is a good tool.
It uses the same drain hose fitting as the one for the generator

Does anyone know if this is the same P/N for the 10k Onan?

Gregg, looking at the Femco web site, it appears they have a drain valve for everything from lawnmowers to earth-movers and just about anything in between!

I like changing my own oil, but given the capacity of the X15 engine in our coach (14 gallons/56 quarts), I've delegated that to shops better equipped than mine. A Femco valve would make it more do-able, but still...

99.9% certain the drain plug in a 10K Onan generator is identical to the one in a 12.5K Onan generator.

Thanks!

The FEMCO valve is definitely the way to go on this issue. The Fumoto valve is not optimal as there have been several reports of hitting them or ruining them if the coach bottoms out or hits some debris on the road. The Fumoto valve is a much longer valve.

I don't remember my exact model but the picture that Brobox posted a few posts up looks exactly like how my Femco valve looks when installed. A nice feature for me is that the standard FEMCO valve has a short drain pipe that I use every time I change oil as it reaches down to my oil catch pan and does not do any splashing..... I simply wrap it in paper towels to store after first letting it drain vertically overnight and before re-storage.

Doesn't answer your question, but I don't remember them offering both valves when I bought mine and cant imagine what else they could do to make mine any better, but whatever Chuck says is probably what I followed.

Larry, I used the standard 10-22150-11 valve. Reason being, you still have to connected the drainer to get the valve to drain. The standard fitting gave me that room. The compact valve would be up inside of the skid plate making it hard to connect the drainer. That was my thinking I removed the hose that comes on the drainer so I could slide a gallon jug under the valve. Works perfect for me, I never have to clean a drain pan. Screw the cap on the jug and drop it off at Walmart on my way home.

[LWBAZ]

Gary & Chuck, thanks to both of you for the additional info! I'll go with the Standard valve.

Regarding the drainer, Femco is now offering a brass drainer without a hose, which fits the 10-22150-11 valve:

https://www.femco.com/standard-drainer-lb-m26x15-650118

It doesn’t appear to come with a hose, but based on what Chuck described I may not need one anyway. And if I do, I can easily add my own.

[brobox]

That would work for me. A gallon milk jug fits under it with enough room to turn the drainer off to switch jugs. I keep the drainer in the round cardboard tube the valve came in in a drawer of my tool box. It would be an easy item for me to lose.

[LWBAZ]

Just placed an order for a Standard Drain Valve and the brass Drainer pictured in my post above. I'll loop back with an update once I receive the parts and get them installed.

Thanks to everyone for the comments & advice - much appreciated!
