Hello,

I just bought a Toto Washlet and am now having problems with the toilet connector hose leaking (forgive me if I'm using the wrong terms here, I'm a newbie to this) after I installed it. I've attached a photo. The leak is coming from the just above the metal part that's connected to the valve. Do I need to get a longer hose or something else more complicated?

Please help. Thanks so much.

You did not put any teflon tape around the threads to the connection. Your photo did not show up on the question but I can figure out the problem in a heartbeat. Go to the store and get some white teflon tape (about $2 tops). Only wrap it around twice around the exposed threads. Then carefully put the connection together again and don't overtighten so you don't strip out the threads but have it tight enough to hold the connection properly.

TURN OFF THE WATER FIRST though before you do anything!

Twinkie:

Take a look at a compression fitting. Where is the sealing surface? It's between the ferrule and the fitting and the fitting and the ferrule. The threads are not part of the sealing surface, hence the Teflon tape may prevent a seal when used in this application.

Your picture does not show. There are two types of supply tubes, the thing you are calling toilet connector. One is a hard metal tubing with a chrome finish. You have to bend these to the shape you want. They make a water tight connection by compressing a brass ring around the tubing when tightening the nut. They must come straight out of the valve in order to seal. If you used the one from the old toilet you may have this type.

The other type is flexible and has a braided metal sheathing or a plastic coating around it. This type uses "o" rings to seal. This type almost never leaks.
Suggest you use this type. Be sure to get one that fits a toilet, they are different from the ones that fit a faucet.

There are more than 2 types of supply tubes if you want to include PVC, CPVC, etc. Most do not require teflon tape to connect since compression fittings are the very most common.

Thanks for your help, twinkiedooter and hkstroud. I tried taking the plumber's tape off and handtightening with only one turn and the valve itself started to leak. So, I ended up having to replace the valve with a quarter turn valve and did not use plumber's tape. This seems to have done the trick. Thanks for your advice!
