We have had to part ways with our pool builder and are trying to assess what is left to do. His parting words to us were that our pumps were not big enough. Another company we had out (who is too busy to help us finish) said that we should have had a separate pump for our 4 waterfalls (3 on pool wall and 1 faux on spa). Does this ring true for anyone? Are your water features separate from the pumps that run your pool?
