I have a 150' 6" well with 140' of plastic pipe. The well has been in place for over thirty years and has always worked great. I now have a Meyers vertical jet pump Model# VMH75 that has been in use for over ten years. It still works great, but the pump has developed a shaft seal leak. I would like to replace the pump, but not the foot valve since it's 140 feet down and still working good. I don't mind to install a vertical or horizontal pump. I don't think they make that same model pump any more. What pump could I use?
