Hi folks. Here's my issue - I have a Head Mate by Willcox Crittenden in my 1996 Excel 26SE. This is a low-end head with a manual pump for flush and dry drain. It just started spraying water up past the pump handle shaft on the flush stroke - sea water, not bowl water. Seems obvious to me that there are some seals that need to be replaced and I have looked at getting one of the standard repair kits for this unit. However, those kits run about $60 (the whole toilet pump cost only $130) and before springing for it I want to make sure it will fix the problem. Anyone on this board have a similar problem in the past?
