flexible water hoses for your taps

^opm^

on the inlet side of my toilet cistern i have one of those flexible metal hoses but before it goes into cistern it has a isolating valve put there,it has a very very slight leak on that joint, i have tightened the connection up, put loads of jointing paste around it and even put a new flexible connection on but can i get it to stop leaking-no-any more idea's oh and why is it since i have messed with this my water pressure has gone down in that part of system-has the paste gone back down pipe and clogged something up but been like it for over a week now-any idea's please :-/

if the pressure as reduced,

and you didnt touch the main stopcock,

then the small valve must be set too far off

I am not a plumber, but I usually do my own. Can't quite see what you see but one of the following three options might help.

You can get some sealant from a plumbers shop. Can't remember the name but it costs about £4.50 and comes in a bright yellow tube. It goes off in contact with water - excellent stuff. Went to garage to have a look .....Fernox LX-S Leak Sealer. I would open joint, clean it and apply with a match stick, also use PTFE tape on the thread.

I have had an issue like this before. If you overtighten then you can compress the olive. You could buy a new olive for 10p, cut an inch off the pipe and have another go.

Not sure what you mean by paste .... do you mean plumbers mate? If so, you should really get some ptfe tape and wind it round the threads (as above). Forget the plumbers mate (I only use that for sink outlets). The tape shoud be sufficient and take up any slack. Get the cheap stuff at 25p per reel as this is the same as the expensive stuff that they sell in homebase etc.

Hope one of these is of some use.

PS I had a tap once that used to flow really slowly. Eventually called the builder back in. Took tap off and let water flow for a couple of mins and out popped a big bit of sponge. Put tap back on and it was fine. So, that is probably a good way to go.

will have another play round with it when i get time-thanks

System

Forget about winding the PTFE tape around the thread (only do this on rad valves) wind it around the olive at least 15 times, this will definately stop the leak. As for the isolation valve you mention remember this, fully on = screwdriver recess inline with pipe.
fully off = screwdriver recess across the pipe

On and off is a quarter of a turn.

Just a point on stop taps.
When opening always close a quarter turn when fully open since this prevents the tap from jamming open. The last thing you want is not to be able to turn off the water in an emergency.

Not such a bright spark.
