It sounds like something is wrong, maybe the valves do not work like you think they do or something is clogged. That said, interconnecting tanks is not a good idea. This will cause a lot of weight to move to the low side every time you tack if the tanks are not full and anytime one tank is drawing air it may prevent the pump from working even if the other tanks is full.

I have a 30gal water tank under both settees. The valves for each are set to open flow. However, the pump seems to draw only from the starboard side. I’d assumed that with both valves open, the tanks would equalize, but the stbd tank empties and the pump goes dry, while the port tank remains full. Can someone venture to what’s going on? I’ve read this 2015 discussion<https://protect2.fireeye.com/v1/url?k=24a815b6-7b332d7c-24a83cc1-0cc47adca788-2a45cfe338c067da&q=1&e=a50a07b0-b170-4e04-8146-7b9407d8b101&u=https%3A%2F%2Fcnc-list.com%2Fempathy%2Fthread%2F2KB2NSDGELMQQJSRMPPWPHVMCWQJ2ICR%3Fhash%3DSLQZNGDWP5TUBYWW6HFGKHJT5DVCWB5F%23SLQZNGDWP5TUBYWW6HFGKHJT5DVCWB5F>, but the OP then was interested in disconnecting the two tanks. I’ll do some exploring tomorrow to see what might be preventing the tanks from equalizing. Ideas are welcome.
