Many outlets/inlets on water tank ??

[waynes world]

Now this is new to me, even after working on many many oats over the years. I cant see a reason for this either.

Can any give me an idea why this FW tank has all these outlets/inlets ?

As shown, the bulkhead fittings in yellow are connected by pipe work under the tank. The lower ones are just connected to each other, the upper ones are same but then T`d off to the Heads and a bulkhead fitting in the hull.
I was thinking breather pipes but there is no need to have all this pipe work and water is drawn off that fats for much venting.
The filler is the standard 40mm and outlet is 15mm to the water pump then to the sinks in galley and heads. although the pipe work to the sink from the pump is T`d off to both taps so cold water to both taps in galley sink.

Think i will just block off the unnecessary holes. less pipe work less chance of problems. Still i wonder what they are for.

Oh yes its on a MK2 Fairline Fury

My guess would to allow water flow when heeled?

I dont disagree with you but i question to get my head around it.
The outlet is in the lowest point so will only ever get the same amount of water to it no matter what the level the boat is at. yes ?

Perhaps some means of recirculating the water to filter it, or suchlike?

Has it had another tank at some point?

filters are fitted after the pump though, i think, not sure on that one. but all extra outlets are linked.

All original and nowhere for another tank to be fitted.

I am just going to block them off. no need for them, and as said before less chance of a leak in the future.

thanks for the trying to work it out chaps very odd bod thing.
