According to California Plumbing Code, a cleanout is required for every horizontal drain line that runs 5’ or longer. So…

What is a Plumbing Clean out?

A plumbing cleanout is an access point installed on a drainage line for the purpose of accessing that line with drain cleaning equipment.  Most houses have them on their drain lines.  The problem is that, quite often, they are not really as “accessible” as you would think.  In fact, most of them are located under your house, in the crawlspace (assuming you have a house with a crawlspace).

These cleanouts are not really “accessible” for a few reasons.  One reason is that the plugs (that keep the sewage from flowing under your home) are usually frozen solid, and nearly impossible to remove.  They have been there since your house was built, and were installed very tightly.

The second reason is, even if you can get the plug removed, all of the sewage that is backed up in that pipe will now drain under your home (as well as all over the plumber who removed the plug).  Remember, if your line is backed up it is likely holding gallons of sewage.  You do not want that draining out in your crawlspace (or basement).

The third reason is that, even if you did get the cap off, and did not flood your crawlspace, it is usually next to impossible to get drain cleaning machines down there.

Do I Need an Accessible Cleanout?

That really depends on the situation.  Many smaller drain lines, such as kitchen sinks, bathtubs, and the like can be cleaned without having to have a plumbing cleanout.   There are sometimes exceptions to that (such as in the case of back-to-back fixtures, etc.), but often there are other ways.

In the case of mainline backups, however, there are not very many good alternatives.

Mainline Cleanouts

If your sewer main is backed up, and you do not have an accessible cleanout, your plumber will be hard pressed to be able to find a way to do a proper cleaning of your sewer line.  These are usually your only options:

  • Have the plumber install a cleanout – This is your best option.  It is a little more expensive than the other options, but is much less so in the long term, and opens doors for other options, such as sewer video inspection.
  • Removing a toilet and accessing through the “closet bend” – This is your second best option, but it is messy, not the most safe option, and has to be done over and over every time your sewer backs up.  It is also fairly costly.
  • Access through a smaller line (Not recommended) – Accessing the main through a smaller drain line is a terrible idea.  The main reasons are that you cannot use a big enough cable (with the proper size cutters) on a smaller line.  Once the small cable hits the blockage, it can double up on itself, and tie itself into a knot.  At that point it will be stuck in the line, and no amount of effort will get it out (short of finding it, and breaking the pipe).  It also cannot do a good job of cutting the roots away, since the blade is too small.
  • Accessing through the roof – This might seem like a good idea at first, but it really isn’t.  There are many reasons why (too many to list in this article), but arguably the biggest reason is that it is so unsafe, and such a bad idea that it is actually illegal. However, there are still plumbers out there that will do it.  Their reasoning is (and I quote a source I will not name here), “By the time OSHA is notified and comes out to investigate, we will be gone”.  Trust me.  That is not the person you want in your home, working on your plumbing.
