New ball valve fitted - noisy tank now!

[goldbyron]

Hi
Just had a plumber fit a new ball valve in cold water tank as it was causing the overflow to leak outside. No problems with the overflow but the tank is making noise filling up when using the HW now. Have done a google and it sounds like the new ball valve could have a low pressure fitting but the water is high pressure?? Does this sound right and can the plumber easily remedy this? Thanks

Only a rank incompetent would put a low pressure float valve on a high pressure supply.

What sort of noise, water splashing into the water, a whooshing sound, a whistle?

Was it noisy before he left? Was he advised that you were not happy with the noise?
Is there an isolating valve prior to the float valve? It may not have been opened fully. That will cause noise.

Cistern will fill nice an quick though .

LOL - I won't tell the plumber this. I went into the loft and the noise is clearly coming from the pipe that feeds from the mains into the tank. It's like a loud humming noise which sounds like the water pressure is too high. The tank is filling fast but the tank itself isn't making the noise.
Rang the plumber who is coming out later this week - he thinks that he fitted the correct valve. Could it possibly be anything else though? And I am assuming, noise pollution aside, it's safe at the moment?
Thanks

Does the noise abate when you grip the pipe?

Could just need some decent support.

No it doesn't stop it but the pipe isn't moving or anything. It just sounds like the water is running faster and louder (?) with the new ball valve which is why I thought the valve wasnt right for the pressure. The noise is audible from downstairs and is just a much louder version of how it sounded pre bew valve. Does this make sense and is it likely the wrong prsssure ball valve? And is it safe for now? LOL

Maybe the " plumber" was gripping something and abating in your roof
