Viega 43003 – Frequently Asked Questions

1) Should I use a straight stop or an angle stop for a toilet supply?
Use a straight stop like the Viega 43003 when the PEX stub comes out of the floor or comes at the fixture in line with the supply riser, so the water keeps going the same direction. An angle stop is what you want when the stub comes out of the wall and the riser has to turn up to the tank. The 43003 is straight pattern with a closet outlet, so it suits the floor-stub-up layout on a toilet or lav.
2) Is the Viega 43003 stop valve metal or plastic?
The body is PolyAlloy, Viega's engineered polymer, not brass. That matters in two ways for a property manager or plumber: there is no dezincification or galvanic issue where it meets PEX, and it will not be a brass-finish exposed stop. It is made in the USA.
3) Will the Viega 43003 fit behind a toilet in a tight rough-in?
Overall the valve measures 3 inches by 2.13 inches by 1.16 inches and weighs 0.097 lbs, so it is a compact stop with a small footprint behind the bowl. Measure from your PEX stub-out to the back of the toilet before committing on a very tight rough-in.
4) Is the crimp ring or supply line included with the Viega 43003 valve?
The 43003 ships as the valve only. Crimp rings for the 1/2 inch PEX inlet and the closet supply riser to the fixture are separate items, so order them alongside if you are stocking a job.
5) What is the Viega part number for the 1/2 inch straight crimp closet stop?
Viega 43003. It is the PureFlow straight stop valve in PolyAlloy, 1/2 inch crimp by 1/2 inch closet. Order by that number to get the straight pattern rather than the angle version.
