Recently got a sump and hob overflow. Think it’s the eshopps 800. Works great but my plumbing always has a leak from the overflow bulkhead down to the sump. Is there a really easy way to do this? Like just with 1 tube? Someone please lmk with pictures or instructions! Need to fix this asap because I’m losing water even though it’s only drops I can see my sump level dropping day after day.
