The mains feed into my water tank in the loft recently started to shake like
mad when filling up, I've watched it gradually start to fill up then when it
gets to a certain point the whole pipe shakes like crazy and this causes the
float to jump up and down causing the water to splutter into the tank - this
lasts around 2 minutes before calming down.
2 things I did before this started happening a) Fitted bathroom sink and b)
removed radiator from the bathroom - thing is, I can't see how they would
have an effect on the mains feed into the tank!!
Most likely disturbed the rigidity of the feed pipe, even just
a minute amount. Another possibility is if you truned the water
off and now it's back on, the flow through the main stop cock
might be slightly different.
Easiest fix is probably to brace the pipework better to something
more solid. You could test this simply by grabbing hold of the pipe
and check this stops the vibration. The brace doesn't need to be
rock solid, but more solid than the pipe itself. I did this with a
tank, and it consists of a piece of 1x1 timber with a pipe clip on
the end, just wedged at the other end inbetween the timbers
supporting the tank -- that was enough to stop it.
Another fix would be to replace the ball valve with a Fluidmaster
Thanks, I did consider this as it seemed like the easiest option, I did hold
the pipe and it was enough to stop it shaking, one more thing I need to
check is if the stop-cock on the mains has been fully opened, I'm suspecting
it might not be.
Me too. :-((
And when the plumber came to change the stopcock he couldn't turn off the
one out on the front path. So the water Co had to come and change that one
first, then they flooded the street because they thought they'd turned off
the supply but it was on a ring main arrangement, then when they put it all
back together we had every cold tap in the house spitting gravel and the bog
cisterns got jammed. Finally the plumber came back, changed the stopcock,
but then I had to change all the tap washers because of the grit embedded in
them making them drip.
And all I had intended to do in the first place was change a tap washer :-))
Got there in the end though.
