Low Pressure Brass Side Entry Ball Valve for Header Tank - can you get?

[andyr123]

Hello all - Has anyone seen or heard of brass side entry ballcock valve for the Header Tank in the loft ,but for low pressure mains water, or do they even exist? - All I can find when I do a search is the high 1/2"pressure brass ones - I can find high and low pressure Toilet cistern ones but they are plastic body and thread. - we have very low mains cold water pressure in the house and I am just wondering if it would be more ideal to change the ballcock in the header tank to a low pressure brass valve if they are available.
