less holes as possible in storage tank?

[ifreefingwasaperson]

Im trying to limit the number of holes drilled into norwesco tanks. Im adding return from pump and sediment filter, float valve, dos awc, heater, temp probe, optical sensors. Ive read about the uniseal and pvc with a cap. I think i would rather go through the lid instead of the tank. Any ideas ? Pics? Could I eliminate the float valve and depend on the apex and two solenoids and maybe a flo lok sensor for protection? I did some maintenance recently and found discoloration on all the float valves. What are the blue center pieces for on the caps of the tanks?

a replacement lid is only 10 bucks. i believe going through the top makes more sense.. pic and ideas of going through the lid??

why not just use bulkhead fittings?

Bulkhead for return, I saw a few post where they pass the wires through a uniseal and use a piece of pvc and a cap to seal it. Just figured the tank would be worth more without all the holes in it

I like the uniseals. I run my pipes through them without any leaks. Run wire through them then plug the rest up with a rubber stopper. I don’t want anything in the lids so I can take them off to add salt, drop my graduated cylinder in for a measurement, etc.
