This is how a dirty water pump should work
Before we had this pump, we were using a VETUS product and we were constantly having problems. However, since it was always due to the negative pressure, complaints about installation errors were rejected by the user. Then the day came when the pump had gearbox damage and the warranty period had expired and we looked around for a replacement product and came across the JABSCO bilge pump at SVP. :-) Since installing this pump there have been no problems with the vacuum or other... Absolutely quiet and reliable! It should always be like this!!
