I need to renew the exhaust joker valve on my Henderson Mk5 bilge pump. Everything else is ok, but it appears that I have no choice but to shell out around £25 for a full service pack that includes the diaphragm and other bits that I don't need. You may well say that the other bits will come in useful -- about as useful as the "other bits" I have from my previous Mk5 service pack purchase a couple of years back. Almost cheaper to buy a whole new pump ( sadly the £20 MkV special offered by ASAP does not suit my installation. Does anyone sell inidividual spares for these pumps?
