New plumbing, pumps and taps

I have spent the last two days ripping out the old sink plumbing, laying new hoses and installing new taps and water pumps.

Originally there was hand operated pump taps at the galley sink and in the heads pumping fresh water from a 150L fresh water bladder tank. Have you ever tried to wash your hands and pump water at the same time? They leaked and the galley counter top has rotted around the taps. They had to go.

My options were a foot pump or electric pump, I found a water pump with a built in pressure switch, I was not sure if it would work without a pressure vessel but they were not expensive so thought I would give it a go. I mocked up a system before starting to rip out the old taps and it worked.. really well 🙂.

The taps are designed for hot and cold water supply, I don’t have hot water but I do have sea water, a very big supply of it. Most people seem happy with salt water washing and fresh rinsing so I plumbed the ‘hot’ supply to sea water from the toilet supply through hull. This line has its own seperate pump mounted slightly higher to keep it above the waterline (in case it leaks).

Both taps have pull out hose attachments so now I can take a hand held shower. Water can drain into the bilge but I will make sure most of the soap goes down the sink and I run a flush of water down afterwards. My bilge pump is in automatic and in testing coped well with the flow.

I read a lot of conflicting views online on using the bilge for this. Many reported no problems, others said yuck it will smell. Time will tell but my view is as long as I run lots of sea water through the bilge at the end of the shower, this may result in cleaner bilges.

Due to the rot around the old galley pumps. I sacrificed a chopping board to cover the old holes, create a mount for the new tap and provide a watertight seal to halt the rot. Visually it’s not great but it is functional. At a future date I will replace the entire counter top.
