Shower drain

My 5th wheel is almost 4 years old. The drain in my shower is draining slow. I have purchased a tool from Home Depot to remove the hair. It helped a little bit for a little while but it is now draining slow again. Is it safe to add liquid drano in the drain of an RV or will this hurt the plastic drain or holding tank?

Our KZ owners manual actually says to use liquid Drano. They wouldn't say that if it could potentially damage something. Have used it twice in our black tank and no issues afterwards. Liquid Drano will not damage plastic or metal. For bad clogs and holding tanks, it's the best thing going.

Drano info.

If using a competitor's product, make sure the label says it will not harm metal or plastic.

I thought there is usually an access cover for a shower/tub. Ours has a twist off cover. Our old TT had about a 4x4" cover made from luan plywood on the side of the tub. If you have a cover you can pull the P-trap out and clean it.

"twotoes".....Often people miss it on the RV drains, but many have a double screen. Remove the chrome screw/screen in the shower and check underneath for a second drain screen.

Several months ago I had a guy wash and detail my MH. I also had him snake the shower drain from the shower roof vent. He pulled out a lot of hair. The shower now drains properly.

I have 3 roof vents. The shower, kitchen sink, and toilet have their own roof vents. The bathroom sink has one of those sink air vents on its drain.

Once you get it draining properly, get a screen insert for shower. We have used one for several years, never had a problem with slow drainage. We do clean the screen after each shower.
The screens are available on-line and at RV supply stores.

I made a tool that fits into the shower and sink drains tightly. I attach this to my garden hose and turn it on and it clears the drain quickly. I find I have to do this every other year because of slow drains.

I use the baking soda /vinegar/hot water trick it will blow out anything that is stuck in a p-trap! It is AMAZING how well it works.

I use it on a regular maintenance basis for both the MH and the house. Keeps all drains slick and clean and draining fast.

We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.

No drano for me. Clorox may not be good either but does a great job clearing hair from drain lines. I myself would find a physical fix as others have posted a plunger should work great. Just make sure you have the shower filled with water as high as possible and plung away!

Bad for the seals in the drain valve
Try boiling water then repeat


And do it once a month as a preventive.

I have used Drano a time or two. I just make sure there is water in the grey tank to lessen any effect it may have on the drain seals. After the shower drain runs good, I dump the grey holding tank.

You might try the vinegar and baking soda trick. Here's one source: http://www.crunchybetty.com/clean-your-drains-with-baking-soda-and-vinegar-surprise
One of these days I'll learn how to hyperlink...
I'm thinking you didn't get all the hair out of the drain. Don't know that tool you bought but there are some about 3 feet long that should get it all. One kind has `velcro' on the end and others have barbs along the length. I get them from Ace hardware.
