Shurflo pump leak

[Phil J.]

Has anyone successfully resealed the plastic casing joint on a Shurflo pump. I've done a lot of searching around for answers and it seems to be a common problem. Someone has used Hylomar but said it was toxic. Mine is working fine but just has a slight drip from the joint.
Thanks

Yes, I used Hylomar and yes, it is toxic.
But consider the actual amount used.
Almost all of it is squeezed out when the screws are tightened and the remained will be microns thick.
It has done us no harm and definitely sealed the pump.
You would probably get more toxins from shaving gel.
