I should also note, that before i had the pump changed, there was a paper whole house ctaridge filter on the irrigation system that I would only need to change once a season, no sediment at all. So the problem did start with the new pump.

How deep is the well? Is it a shallow well? If so you may need a sand removal filter. The attached link shows an automatic model which purges sand at a variable setting. It can be purchased at one of the big box retailers. The item number is a Lowes item number. You may be able to google the model and find another source.

My first well was sending sand up and when I researched the well log, the driller only went through 85 feet of sand/silt. I had them drill another well deeper and through the rock layer to water on the other side. No sand, but plenty of iron here. I have an iron filter which works Great.

Hope this helps,

Take Care
