bathroom shut off valve

Hello

My toilet has been running and running. I changed the flapper and it didn't help. Then today I changed the fill valve, a Hush Flo. When I turned the water in the bathroom off and removed the supply tube from the fill valve shaft, water continued to very slowly run out of the supply tube. I put the supply tube in a bowl to catch the water and filled it up twice while I changed the fill valve.
When I got eveything hooked back up and turned the water on and flushed, the tank filled back up and the water shut off. But I noticed a small ripple coming from the new fill valve. That's not supposed it happen, is it? What do I do now?

Thanks,
Donna

Supply tubes rarely reseal especially if they have any age to them.Yours is not resealing.What needs to be done here is replacement of the supply tube and the supply valve as it sounds like it no longer is shutting off.Most supply valves dating to the 60's or newer were made in ways that are not generally repairable so once they stop working they must be replaced.Older valves sometimes can be repaired but are often too aged and brittle to stand up to the effort.Bottom line...replace them both.

Thanks. Is the supply valve and supply tube something I (someone who can read and follow directions) can replace or do I need to call in a pro?
Thanks

Every situation is different.It would depend upon exactly what type of supply tube and valve are in place and what their condition is.Generally supply tubes are easy to replace and the easiest replacement tubes,as well as the most effective and fool proof,are the re-enforced vinyl or stainless steel types with the fittings pre-made on each end requiring only tightening up to install.this is assuming your existing set up will work with these...a good bet but without being there not a certainty.The valve is a different story.If it's soldered in place that's obviously different than if it's screwed in place.If the pipe coming out of the wall is galvanized steel and if it's been on there a long time then there is a risk it will have rusted and be weak and possibly break off.If it's screwed to a copper fitting and has been on a long time it could ring off the copper.The more age involved the riskier it could be and the more possibilities of different types of set ups you might encounter.My thinking would be if it's been there longer than 25-30 years and you don't feel comfortable doing it yourself then call someone in.Less age than that might open the door for you to do it but you'll have to judge for yourself.

P.S. I left off the most likely valve mounting which is a chromed cast brass pipe nipple.Again age would be a big factor in this situation as brass brittles with age.also if it was screwed on tightly the whole nipple might screw off with the valve.You'd only know what was going to happen by trying.If it didn't come off easily or the nipple started unscrewing you'd probably be better off letting a professional do the job.

Donna747,
Is this "ripple" inside the tank? If so, it may be that the fill valve needs adjusting. A ripple inside the tank would indicate, to me, that the fill valve is not shutting off the water supply completely when the tank is full. watch the tank water level and see if it rises. The water should be a 1/2 to 3/4" below the top of the overflow tube. Good luck.
