earl964 Posted June 28, 2009 Report Posted June 28, 2009 I have a haywood ec-40 that keeps losing return pressure. I have cleaned it several times. I have even soaked it a acid/water solution. When I put it all back together it runs fine for about 25-30 minutes then the pressure slows right down. Then I bump it two times and the pressure comes right back for another 25-30 minutes. Any help would be great Quote
