11.6 Checking Purse Line Adjustment
Once the lines are adjusted, fill the Bambi half full, with
the water just below the top of the valve. Check to see if
both lips of the valve are matched right across the top.
Sometimes one lip will ‘track’ slightly above or below the
other as shown in Fig. 14.
11. ADJUSTMENTS
Fig. 14: Dump valve showing one lip tracking above
the other.
Fig. 15: Pulling the purse line to bring lower lip into
alignment.
Usually one or two specific purse lines will cause this
improper tracking. To correct:
1) Grasp the purse lines at the centre of the section
of low lip as shown in Fig. 15.
2) Pull it/them several times to bring the lip into
alignment.
3) Re-tie the purse lines so that the line is just snug.
Do not over-tension this line. Over-tension will result in
misalignment at another position on the valve.
