Can this type of stuff be used down the gray lines to get rid of hair, etc build up? If not what can be?
thanks

I do but I used the less powerful one so I don't eat up the walls inside my tank... And only do it once every three or fours months so you don't do damage I use it but I do it quaryerly when i use the coach so I don't damange the walls and lines...

Liquid Plumber will not "eat up" the walls of your tank.

Liquid Plumber will only dissolve organic material.

Liquid Plumber is safe to use in an RV.

"Lab tests confirm that all Liquid-Plumr® products are safe for all household plumbing. However, we do not recommend using drain openers in rubber pipes. The products may damage rubber. "

I don't think many RVs use rubber pipes.

No, but I believe they do have rubber seals.

What if you use it when the gray tank is fairly full and then dump as soon as you're finished with clearing the pipes? I'd think that the Liquid Plummer would be fairly well diluted and wouldn't be remaining in the tank long enough to harm the seals. I certainly wouldn't use it with an empty gray water tank.

Unless it is really bad you can maintain your drains with Arm & Hammer baking soda. If you use it in the refrigerator for odors, when you switch out the box empty half of the box down each drain and follow with about a quart of HOT water. Works well.

Linda,
You have the right idea. I have used several household drain cleaning products over the years. I always get the grey tank 3/4 full first. Then use the product according to the instructions. Rinse the drain thoroughly and dump the tank. Rince very thoroughly again and dump again. I have had no leaks.

I have been using the Cascade dishwasher "pacs", 2 each in both tanks. Once a month, after draining the tanks and just before we pull out for long haul that day, I add the packs and 3 or 4 gallons of water. The in-route swing and sway splashes the mix all around inside the tanks.

At the next campground I wait until the tanks are 3/4 full or add water to get them there and then dump. This has kept our tanks extremely clean and the level sensors free of muck.

I do not use any other chemicals or additives what so ever, as this procedure has kept the tanks clean and oderless from day one...it is cheaper too!

I would never use a Liquid Plumber type product as it WILL damage the drain valve rubber seals and rubber joints and couplings used in the 3 inch piping before the drain valves.

RVs don't use rubber seals anymore because they tend to rot. The few seals that are used are made of neoprene or other synthetic materials. Liquid Plumber and other chemical drain cleaners will not adversely affect the plumbing in your RV. The only exception would be an older RV (i.e. one made in the 1980's).

I've used Liquid Plumber sevarl times. However, the best way to clean out a drain is to take it apart and clean it manually. The only place I haven't been able to do this is in the shower. In this case, the pipes are difficult to access.
