Septic clean out cap

Submitted ⁨⁨3⁩ ⁨weeks⁩ ago⁩ by ⁨batvin123@reddthat.com⁩ to ⁨3dprinting@lemmy.world⁩

So my dad broke the septic clean out cap with the lawn mower. He cannot find a replacement that is lower to the ground so I am printing a new one. Should I use PETG? Or another material. Also I hope this is not violating some form of regulation in the U.S.

ASA is the peak material for outdoor prints with the best uv and weather resistance. It is quite a bit expensive but worth it imo if it’s not something you want to replace every 2 years.

How big is the cap? Is it a threaded pipe clean out cap or a manhole sized cap?
There are codes regulating the loads a septic cap has to support (preventing people from falling in) as well as some need for atmospheric sealing. If you have to print in multiple sections I don’t know how tight you can make it and how strong it can really be if there is glue involved.

  Agree on ASA. I have some PLA+ prints that have been outdoors 24/7/365 for going on 5 years now and they’re holding up really well, so that’s another good option.
  
  I’ve been printing ASA for about a year and a half and haven’t dried a spool yet. I guess it all hinges on a mix of relative humidity in your area and how much you care about a flawless finish.

    Are your PLA+ prints taking any load at all? I have some PLA+ pieces that I have printed to repair outdoor Halloween and Christmas decorations which are at some stress points in the decorations and I have to replace them at the start of each season because they get so brittle by the time the holidays are over.

    Ehhh, I find that PLA doesn’t survive well in continuously wet environments- gets kinda cheese-y like.
    
    Thats interesting you havent had any problems with it being wet though. ASA must be a lot more sensitive to manufacturer, because I had four complete spools of Bambu that just wouldn’t do shit without drying, and I’m about 30/80 on spools of Overture ASA that need drying vs don’t.

    Did you anneal your PLA+ prints or did they go outside straight off the printer?

  Maybe chemistry is an issue too. Septic is what, methane/(?)?

    ASA is basically inert unless you’re dealing with weird acids or acetone so I don’t worry about the chemistry too much. PETG will generally be a little better chemically but nothing that you’d see in a sewer.

I don’t know about other materials so make that decision first but I’ll say opaque PETG will do better with UV than translucent.

But honestly just paint the top that’ll be getting baked by the sun.

Make sure it’s not like, going to get crazy hot in the summer and melt to the opening and seal it, that could be a nightmare.

ABS is probably the best since it’s more resistant to UV light.

  You mean ASA?

  PETG has better UV resistance than ABS

Generally, regulations are for construction contractors. You likely won’t pass some kind of plumbing inspection if you hired a contractor to do something that requires a permit, but otherwise your free to do whatever. I’m no expert here and you should be doing due diligence. My old man does inspecting type work in another type of industry and this is how it was explained to me, but that is an unrelated field. Different regions may have very different regulations.

  Erm, no? Most municipalities require building permits, even for homeowners to do work on their own home, and those permits require work be done to code.
  
  Does that always happen? Of course not. I also went 5-10 over the speed limit on the freeway yesterday, but that doesn’t mean regulations are for commercial vehicles only.

    There is usually a dollar amount involved for what can be done before a permit is required. You’re allowed to make minor changes required in the spirit of maintenance. So something like replacing a refrigerator and the old width being too small. If you cut the countertop to accommodate, no permit is legally required. The same can be said about almost every aspect of the home. That margin of what exactly is considered maintenance versus modification is what varies by area.
    
    The other factor I’ve heard is that the changes must fall into what’s undefined on the blueprints of record. If it is not specified in the blueprints, you are free to make the changes.
    
    Again, I’m no expert here. I really wish I had the option to remove the mod badge when I only wish to post as a user. I could certainly be wrong. This is intended as a helpful but just water cooler talk amongst friends level conversation. When it comes to house mods and permits, this is how everyone I know does things.
