leaking toilet hose connection

[rex_seadog]

I have recently replaced the discharge hose on my old Brydon toilet with some nice new white (odour-free) stuff. The end connected to the Blakes seacock was a tight fit and had to be heated with boiling water to persuade it to fit. However, at the other end, at the elbow, it was quite a loose fit and I cannot seem to get a leak-free seal. (My old green hose never leaked). In fact with my first attempt using two jubilee clips (as recommended somewher) the water poured out when I first pumped the loo. On my second attempt I used just one clip but made sure it coincided with the two knurled (barbed or whatever the correct engineering term is?) rings near the end of the elbow. It is now better but there is still a slight weep. I have contacted Jabsco and they tell me to fit dry but as a last resort to use Silicon and not Urethane or polysulphide as it reacts adversely with the ABS plastic of the toilet elbow.
The clip is already fairly tight and I am afraid to put the spanner on it in case it cracks the elbow.
Has anyone experienced similar problems? Perhaps I should let the natural gunge act as a seal over time!!

<font color=blue>What is that tape that Plumbers use? Its like electrical tape, whack that on the pipe, put the hose on top and then tighten it up.

Try either PTFE tape or Fernox LS-X, a brilliant silicone, cures under the action of water and available from any plumber's merchant. Aka Plumber's "Get out of jail free".

If its a really loose and the old pipe fitted well, cut a short piece of the old pipe and put it on the fitting, push the new pipe over both. A bit of a bodge, but its worked well enough when I've resorted to this.

A plumber has recently told me not to use PTFE tape on 'plastic' fittings as it will damage some eventually. It is apparently intended to seal metal threads only.

PTFE tape is basically teflon, and is completly inert, it cannot harm anything it comes in contact with, plastic or metal.

Change your plumber!

don't use tape to pack out a loose hose connection. it will creep and the hose will slide off in time. been there, done that.

Use electrical insulation tape to pack out the joint as a temporary measure and make a mental note to do something proper next year ... or the year after .... or the year after that .... or................................... the next owner can do it if he discovers it.

I had same problem - final solution that worked - was wrapping two or three turns of self amalgamating tape around the male fitting and then sliding the pipe on over the tape.
This gave something for the pipe to grip on when the single jubilee clip was tightened.
