Am I overthinking my wastecap replacement?

[StuartSailor]

Hello All,

I know the answer is probably yes because that’s how I roll. I have to replace my wastecap for hose. Pricing via WM, Defender, etc is between $25.00 and $40.00. Then I saw the Perko unit for over $100.

Are the other units cheap China made products or is Perko for when you’re building a new boat. It’s not the money as much as it’s the money. I just don’t want to pay for a “name” if I don’t have to. Plenty of other things I can apply the extra $50 towards. I appreciate any feedback. Thanks.

Overton's has the complete deck pumpout (waste) fitting--with black plastic cap--for $23.71

If all you need is a replacement cap, Amazon has a bunch of choices for reasonable prices

Thanks for the response and the information Peggie. Definitely need to replace the whole unit after multiple unsuccessful attempts to crack the seized cap free. Is there a reason why you’re suggesting a plastic cap vs stainless? Less chance I’ll have the issue I’m having now I’m guessing.

Not suggesting a plastic cap vs stainless, only including them in what's available. So go with what you want to pay for. If it were mine, I'd prob'ly choose plastic for a couple of reasons: 1. there's no chain--at least there shouldn't be--on a waste cap, so unless you're extra careful to stow it where it can't fall overboard, sooner or later it will and plastic costs less to replace. 2. If all the other deckfills on your boat are stainless, a black plastic cap makes it a lot harder to pump out your fuel or water tank. But to repeat...I'm not recommending either, just showing what you can find for a reasonable price if you use the item you need as your search term instead of only looking for it at the usual marine equivilent of "big box" retailers. You'll be amazed by the number of retailers who have what you need for a lot less.

Peggie, thank you for the helpful response. These are great suggestions and I will take your advice. I’m a big fan.

At some point I may need to post for help re: plumbing/re-plumbing my head to also add a wash down pump and valve to be able to send my holding tank overboard. Too much to think about now.

Check the OD of the deck flange. We had factory installed RC Marine deck water, waste & fuel. Purchased replacements and found the hole in the deck was larger than the new deck flange. The RC units have an offset above the 1-1/2" OD hose barb.

Thanks for the info Notiesbob. No repair job is ever as simple as it seems sometimes. Appreciate the response.

Hi Peg,

I wound up purchasing the perko with plastic cap because your comments made sense.

Was this supposed to come with an O ring? I thought I’d read that on other threads. I can’t imagine they’d expect someone to use the old one if it exists, or do they? I haven’t taken out the old unit since I am waiting until I have all my supplies to install the new one. Otherwise I’ll assume a good amount of 4200 should do it. Yes? Thanks again.

I'm pretty sure it should have come with an o-ring...you might contact Perko to ask them.


As for sealing the fitting in the hole, I'd go with a top quality bedding compound...but I'm gonna defer to others 'cuz I'm always recommending against the use of ANY sealant in 99% of sanitation system applications so I'm not very knowledgeable about the various types and which one would be best for your job.
