I bought one of these in July while suffering from extended bouts of the trots with Norovirus:
It is actually a brilliant little device for when your botty is red raw from frequent visits to the loo.
But its design truly SUCKS. The problem is the water bottle and its screw thread attachment to the spray tube. Almost every time one uses it, the bottle becomes canted away from the tube connection and starts leaking, pouring water on to the bathroom floor.
The bottle is made of cheapo plastic of some kind, and deforms far too easily when squeezed.
So what I'm looking for is a replacement bottle that will fit the tube connection, or some way of strengthening the bottle neck, for example by heating it then freezing it repeatedly just in the region of the threaded part in order to harden the plastic. (Or could this hardening be achieved with a mix of household checmicals?)
Any ideas? Don't say "install a bidet" ! There's NO space available.
It seems such a shame that a good and cheap idea should be let down by such poor design and shoddy workmanship, It is, of course, made in China.
Last question: Would the screw thread be a standard thread used for other products? The bottle neck is approx 36.89mm dia, not including the thread, or approx 39.57 WITH the thread. The thread pitch is approx 2.20mm
For possible reinforcement of the bottle neck, where the deformation occurs and the leakage ensues, I thought of a short strong spiral spring that could be 'popped' inside the neck, which would expand and thus reduce the likelihood of deformation. Haven't tried any of the ideas yet, though. And I wouldn't know where to find such a spring anyway.
Or maybe a metal ring (brass or copper -- e.g. plumbing accessories?) that could be forced inside the neck. The ring could be hacksawn through on one side, then opened up a bit to make it 'springy'.
The only requirements are that the bottle holds water, can be squeezed to send water to the spray end, and is 99% leakproof at the bottle/tube connection when in use.
Further ideas welcome, even a DIY design for reconstructing the whole thing out of 15mm copper tube and a small watering can rose.
