Fitting hand water pump in pressurised system

Use the pressure pump very seldom because it's a water waster and cycles intermittently if left on which disturbs my Zen quiet on board. Have tried to find why the pump is losing pressure without success.

Point taken on the hand pump. Very good point. I do remember it a pain to use, but it looks so cool.. I haven't re-installed either on Vigah. If I have room for a second foot pump, I will go that route.

Pumps can be a pain to track down problems, especially on the suction side. Mine will hold pressure for days, but when the faucet is turned on it has to re-prime after a couple idle hours.

I reckon that the ball valves with their nylon seals ensure no seepage into the freshwater tank from the sea but as well, we chlorinate the fresh water. The sea water source is a last resort if you need to minimise water usage and is not necessary,

Sounds like you want the handpump to be used with either fresh or salt water...............never seen that done.
Most people only use seawater for washing dishes, then rinsing with fresh, thus saving the fresh water.

In any case, you should always run your water before using, especially if it has been sitting for a while and you are not on the boat using the water system every day.

If you are concerned with "things in the water" follow the prescribed and widely published methods for purifiying water..............best advise stop listening to all the media's and ad hypes/crap on "killlng all those bad germs".

Choose your water sources, flush the fill lines before filling tanks,
and if like myself a "weekender" on my boat, is use the water so you can continue to introduce into your tanks, 'fresh' water.

This should never be done. Use a separate spigot.

Well, I decided not to install the hand pump. Instead I installed a Whale Gusher foot pump in series with the supply to the FW pressure pump. Tank - whale - pressure pump. It works great and with it I have hot and cold via the foot pump. In fact Whale Gusher notes state this exact configuration. I will install a separate spigot and foot pump for salt water.
