BPEL vs Length in the tube?
I’ve noticed over the past couple of weeks that my length in the tube is significantly longer than my BPEL. I’m relatively new to pumping, having started about 4 months ago and am wondering if this is common?
My BPEL runs about 6 7/8 to 7 and length in the tube towards the end of a 20 minute session is 7 1/2 to 7 5/8. I pump at relatively low pressure, between 3hg and 4hg, if I were to increase pressure I’m sure the difference between BPEL and tube length would increase even further.
Any ideas?
