tree roots and orangeburg pipes
In one of my bathrooms, the toilet is OK, but the sink and bathtub, which are next to each other, fill with water after a few seconds. Then it takes a long time for the water to go down.
I discovered 4 years ago that this house had Orangeburg pipes (it has some clay pipes; PVC also).
The plumber looked through part of the line with a camera. Some roots were coming through the Orangeburg. There was a small crack in a clay pipe.
I assume the Orangeburg was used when the first part of the house was built, in 1953, and if so it's already outlived itself by quite a lot.
I had the Orangeburg pipe Roto Rooted once (before I knew it was Orangeburg), about 10 years ago, and tree roots had been found then.
But this last time, 4 years ago, the plumber with the camera said not to Roto Root as it could further damage the pipes.
I also heard about a potent herbicide, but that the herbicide too could damage Orangeburg pipes.
I'm hoping to sell my house this year. I'd want to list it as a fixer-upper or a tear-down or 'as is', so I don't want to put a lot of money into replacing pipes.
I want to buy a little more time, but I'm frightened of damaging the pipes further. They are living on borrowed time as it is!
This is a 1-story house, so if the pipes back up, there's no basement for the overflow to go into—just would go into the house. There is one let-out, but another plumber said it wasn't at the right point, not low enough, and if there was a back-up a lot of the stuff would go into the house before reaching the let-out.

Yesterday I tried noncorrosive cleaner (baking soda and vinegar, followed by boiling water) on the bathtub drain, and nothing happened, so I'm pretty sure it's tree roots there too.
The bathroom I got Roto Rooted 10 years ago was a different one.

What's the least risky fix or strategy I could try?
I read one post from a couple of years ago and the suggestion was to feed a hose into the pipe (not a plumbing snake, which might push the pipe over the edge). Has anyone tried a hose, or any other ways to get rid of roots?

There is a chance that your tub and lav are on a branch line and can be cleaned independent of the mainline.
As for the burg- we cable it more then once. Granted, cable knives are abusive and can damage pipe. But IMO, using a jetter or cable are your only options to remove roots and you don't use a jetter on burg- it will destroy it in a heartbeat. Some members on this board will recommend a "chemical" product which I haven't used so I won't comment on it. Perhaps they will chime in.
Replace the line- that's the best option. It's one less upgrade a prospective buyer has to worry about

Remove it, replace with PVC and never have to worry about roots getting in the line again.

Replacing it is the best option.

Once it starts to delaminate on the inside, it only takes a day or two after cleaning it out for it to start backing up again.

I just had this problem with my rental.
