## Questions & Answers

**Q: Why would I want 1” inside diameter versus 0.75”?**
A: 1” will provide more flow.  It really depends on the size of the return pipes in the pool or spa.

**Q: The top part looks gray. I need gray, is it?**
A: The ones I bought from Amazon were off white. Remember when they were in the pool under the water, light refraction will change their color slightly too more of an off-white but they were definitely not gray.

**Q: Is there a performance issue or difference with using a different size opening  ?1/2”, 3/4” or 1”**
A: Small the diameter the harder your pump works. No difference in efficiency.
