Dripping pump any advice?

I got a shurflo pump in my van and like alot of set ups the pipes from the van run underneath to some outlets underneath the back bumper. The pump works fine apart from it doesn't stop dripping sometimes heavily.  Does anyone know how to stop this? at the moment I've got blue tack stuck into the tap to try and stop it lol but it doesn't really . Any advice would be great. Thanks 

You could fit a stop connector on your van port. You will find the drip is 'worse' on some pumps and not on others. We find the fuller the tank the more the drip.

Inside the pump you have a non return valve. It consists of a tiny plate and hair spring. It allows water to flow one way or not the other when the pump is operating. The pressure of gravity (head of water) is enough to push that plate of its seat - hence the annoying drip.

We don't have stop connectors on our van ports. We have tap connectors. When we are finished we use 2 hozelock hose connectors filled with silicone to stop the drip.

Thanks spruce. I think I'm going to try that trick with the silicone 

A picture would be good to see how it’s mounted and where the leak is coming from , I can honestly say never had a leak from a pump 

Personaly wouldn’t worry about an external drip , it is probably draining by gravity from the pump , a tap in that hose would stop it but don’t see that it’s really a problem
