I would like to install a cleanout for my main drain line from my house to the city sewer system. There is no existing cleanout access for the main sewer drain line. House details: Huntington Beach, CA single-family tract house built 1960. Today I dug a hole to access the clay drain line. The drain line was appox. 3 feet below grade. I also found that a 45 degree wye exists approx. 2 feet from the foundation, which is plugged or capped. What materials will I need to connect a cleanout to my drain line? The wye is 7 1/2"OD and 6 1/4"ID. I plan to visit Home Depot and my local plumbing store tomorrow, but hopefully some pro plumbers on this site will chime in. Thanks in advance for the advice! Aaron Here are a couple pictures of my work: Clay drain pipe with plugged wye I dug in the hole in an existing planter between the foundation and the driveway pad. The drain pipe exits the house at the sprinkler riser to my right.

Then I would need a 4" ABS 1/8 (45 degree) street bend, approx. 3' of 4" ABS pipe, then a 4" ABS female coupling, and finally a 4" ABS cleanout plug. Does this sound right? Will I need to protect the cleanout with some sort of junction box, like the tyoe used for sprinkler valves?

If I understand you correctly you're going to fit a Fernco Coupling over the hub of the clay wye and transition to plastic. There is a better way. You could transition to a ABS street 45 using a Duel-Tite Donut , (see image) and then glue in a short piece with a cleanout. Here's how it's done.
First clear and clean the terra-cotta hub. Then insert a 6 X 4" Duel-Tite Gasket, (see image) in the hub. Next take the ABS street 45 that you wish to convert to and file and bevel the sharp edges so it will slip into the gasket.
Next you will need Duel-Tite Lubricant to make the pipe slde in without friction. Apply the lubricant to both the pipe and the gasket. Now force the pipe into the gasket, KEEP IT SQUARE, do not cock it.
If you have a problem getting it started it's acceptable to take a razor knife and shave down the first few rows of ridges. You have just converted from Terra-Cotta to plastic. Good luck, Tom

Thank you, Speedball1! I will be on the lookout for the Duel-Tite donut when I go out for supplies. I didn't even know that part existed. Your solution seems more simple than mine. I will let you know how it goes.

Hi Aaron, I am local plumbing contractor. See, you are doing it yourself and saving about $600.00 in the process. Great job ! Tom gave you excellent advice, but we don't use donuts around here anymore. Inspectors don't like them. We always have to convert to hubless connection. Donuts will never hold inside the Clay pipe tight and will get loose with seismic activity... You should cut off the clay HUB with 4" diamond blade in grinder tool. It cuts easier than you think. Then, go to Home Depot and get 4" Clay x 4" ABS Flex Seal Coupling. ( the actual O.D. is about 6" x 4 1/4" ). Cost: about$10.00. It is made for your situation. Also, ABS glue, 10' of 4" ABS and fittings you make the new pipe to point straight up. Cut off with ground level. Install 4"ABA Female Adaptor (threaded, cost about $6.00) and screw in 4" ABS plug ( cost about$3.00). Job done...

But if you (really) want to look for "donuts" don't look for them in Home Depot or Lowe's. You have to go to more professional store. In O.C. I would suggest that you go to Ferguson Enterprises. Closest branches to you are in :

Costa Mesa (1781 Placentia Avenue, Costa Mesa - (949) 650-0646)
Irvine (1315 N Santiago St, Santa Ana - (714) 547-5797 )
Santa Ana (6 Cushing, Irvine - (949) 753-0039 )

I am enclosing pic of Flex Seal aka Mission aka Fernco coupling for better visual...

Good luck with your project ! Milo

Milo,
Thanks for the local advice! I have a 4" angle grinder with a concrete/masonry blade that should cut the clay hub. Just to clarify, I am removing the flared part of the clay hub so I can connect to a 4" piece of clay pipe, correct?
 Milo Dolezal Posts: 6,027, Reputation: 390 Plumbing Expert #6 Jun 14, 2010, 10:48 AM

Exactly... Cut off that enlarged end. See the pic...

Cutting will produce lot of dust. We always have bottle of water handy, poke a small hole in the cap and squirt water under the blade. This way you won't choke to death in the trench.

Important: Wear good pair of HD gloves and goggles.

Let us know how you did. Milo

I will be sure to use water to control the cutting dust and wear goggles and a mask.

I called a couple plumbers for estimates and they quoted \$100-150 parts and labor. I will go to Home Depot to now to find some parts.

How will I test this connection once I make the repair? The drain should not be under pressure, so I'm thinking I will just test by using my drains inside the house? Any particular methods?

Hmmm... you should send me their phone numbers ! I can have LOTS of work for them !

Each rubber coupling has paper band around it specifying what pipe it can be used for. Don't get confused if it says 4" clay and the actual OD is 6". Go by the designation on the sticker...

Yes, assemble new clean out and run lot of water from inside of the house. Observe the connection for few minutes. Unless you broke the Clay pipe during cutting - it should hold. Forgot to tell you: be very careful you don't break the Clay pipe while cutting!.

Got my supplies: 10' ABS pipe, 4"-4" clay-ABS coupler, 4" ABS 45 deg street fitting, 4" female coupling, 4" cleanout cap, and ABS cement.

I had a plumber come by to estimate and he recommended a 2-way sweep fitting for the cleanout to allow for snaking both ways. This would mean more digging and cutting out the clay wye, then installing a 4" ABS 2-way sweep fitting. Is this necessary?

Another question: Can I leave the cleanout fitting bare in the ground? Or should I install a box around it, something like a sprinkler valve box?

Do you have lots of problems with blockages INSIDE your house ? If not, I would not worry too much about it. You can always remove toilet and snake it from there.

Not much experience with plumbing systems, but I'll try to be as clear as I can. Our basement is not finished, but is roughed in for a full bath.
