had to change the washers to rubber

We had 6 of these & the valves are great but when fitting them we had to change the washers to rubber ones
 
The fibre washers in the box are poor If you can change them, we will definitely buy again.
 
once we swapped them over, the valve was perfect

Great product

I have bought and installed thousands of TMV over the years, the price of these are far better than anywhere else I've previously purchased from and the fitting of them just the same.
