Hi all,
New installation. Conversion of old dutch working boat. No engine.
Drain down points (x3, hot pipes, cold pipes and unpressurised pipe between tanks and pump) are all going to be sited close to each other, under some steps in their own cupboard, which will also contain pump and calorifier. This cupboard will back onto the bathroom, so I will also probably put the shower/bath pump (Whale gulper) in this cupboard as well... Which leads me to thinking... Can I plumb the drain down points into the gulper along with the bath waste (via an L port valve???) and make emptying the water system overboard an easy operation?

Yes, why not. Seems a good plan.

but not water from central heating, if it contains anti-freeze and/or corrosion inhibitors.

No, indeed not. But main reason for draining down is to protect from freezing, which would not be an issue for the central heating with antifreeze in.

I must admit, I use gravity. I've a pair of these in the hot and cold pipes in the bilge before the bulkhead. www.screwfix.com/p/washing-machine-valve-tee-15mm-x-15mm-x/60723Couple of end caps to stop accidentally knocking the valve. The cauliflower now has a drain on it, the cold tank I just remove the pump and let it drain. Remove the shower head and water filter - job done! Bilge pump hoofs it all overboard, easy peasy  |

I'd rather keep it like that! Obviously I could use gravity, baking trays and wet n dry vac etc etc, but it seems a waste not to use the gulper if it is just sitting there. |

It's a sound system right enough. Absolutely no reason not to do it. Ours drains into the engine bay - we have an aft cockpit cruiser so there is a bulkhead between the living space and the workings of the boat. The cabin isn't wet bilge like my old dears Hancock & Lane was. |
