Safe to use drano?

Hello everyone,
Is it safe to use drano or like products in our DRV's drains? Our drains are really slow draining, especially the bathroom one. Are these products ok to use with rv plumbing, they might use different glues etc than a home. Thanks Ron

Drano will not hurt the plumbing, but might not be good for an RV septic dump station--I think it is a caustic soda material with a high pH.
Consider using one of the barbed hair retrievers to run thru the traps to see if a hair plug is present--very cheap item and easy to use. I would also pull the traps and manually clean them if the barb gadget doesn't work.
I think you will find that you have hair built up, along with soap residue and using the barb works well for us.

I went to Home Depot and bought a small shut off valve that would connect to the garden hose. Then bought a length of very flexible clear hose about 1/2 in diameter and maybe 4 ft long. Made that connect to the shut off valve so I could drag the hose into the trailer, removed the air lock valve in the bathroom cabinet, the one behind the wash machine and the one in the kitchen cabinet and snaked the hose into the opening. Having the sewer dain valve open I would then flush the lines into the gray tank. The hose was small and flexible enough to snake around the through the drains in the sinks and the shower drain screen then flush those pipes too allowing a higher pressure water blast than you ever get by running water. Or, you could keep the sewer valve shut and since your only running maybe 10-15 gallons of water through the hose setup then when your done inside go open the dain valve and flush the tanks. It didn't take long to do this and it kept the pipes clean and flowing well. I might have invested $5 or $6 bucks in the hose set up. I used it on a few other friends rigs to help them repair a slow drain issue. I never would use any caustic stuff like Drano to do what fresh water could do.
