sea water fed head switched to fresh water

[mainshiptom]

I have owned my boat for over a year now and this job was a low priority but since we sit on mud at low tide in our mooring and when we on anchor the head always smell's of rotten eggs. I decided to go for it,

The plan was to introduce fresh water after sea cock and have a switch over.

This plan was good but one set back was that since the fresh water are under pressure I had to add a tap on the head, so lots of work and a bit of cost but works a treat!

So next project I would like to replace the head that has a switch built in...Can you get one, all i can see is either a sea water fed or fresh water but not both..

Happy to post pictures if there is any interest.

I did this 5 years ago will never go back.

Have you used a proper toilet valve that’s stops nasties backing up into your fresh water?

I installed a non return valve.

Has a syphon break in it. It was 120UKP so I hope it isn't snake oil.
