Galley Foot Pump with some good pressure.

I am looking for some help here. I am looking for a good Galley Foot Pump for my customers who want to install our Model 500 under the Galley sink in their sailboat. Our unit draws less that 1 amp and is ideal for sailboats. The foot pump would allow them to save even more power.
The main issue is the pressure that it takes to push through the .5m or 1m absolute filters in our system and be reliable. Does anyone have any experience with this issue and/or any suggestions?

Here is a link to our Model 500.

Re: Galley Foot Pump with some good pressure.

I tried using a whale foot pump once with a carbon filter. The problem is that it pumps with your foot pressure downwards but upwards it pumps also. It comes upwards with the aid of a return spring. The spring does not seem to be strong enough to overcome the filter restriction. Hope this helps...CS

Ya...but he was talking about running a foot pump through a filter.

Re: Galley Foot Pump with some good pressure.

It looks like we will be going with our second filter option. It is a 1 micron absolute that conforms to NSF/CDC standards for drinking water. The plus to this filter is that it allows for a much greater flow rate. The drawback is that is that it does not take care of taste/odor issues. Do you think that this is going to be a big issue coming out of an onboard tank?
What are your thoughts?

I use my onboard tank all the time, my guess on taste & odor is that'll depend on the quality of the water you put in the tank. Mine is fine using a Culligan whole house filter & dock water.

Re: Galley Foot Pump with some good pressure.

I use a Whale Gusher galley foot pump to send tank water through a General EcologySeagull IV filter (0.1 micron?).

Re: Galley Foot Pump with some good pressure.

waterfixer -

just out of curiosity. i thought that odor/taste problems were taken care of by charcoal filtering. does the charcoal have to be packed to a 1 micron density? doesn't the flow of water over the charcoal remove odor/taste?

Re: Galley Foot Pump with some good pressure.

...37"
The main reason for the 1m absolute or less filtering is the removal of harmful cysts and algae before the UV takes care of the rest. Carbon filtering can reduce taste and odor in many different micron sizes. Britta water pitchers are activated carbon that is about 25micron or so and they do an ok job. Our .5m carbon block is a great all-around filter, but does have the water flow reduction drawback. j

Re: Galley Foot Pump with some good pressure.

Waterfixer, thanks for bringing this issue up, as I am redesigning my plumbing system to include one of your units. My rationale is that I will be doing the ultimate filtering and UV treatment as my default mode. If I am having electrical supply issues, I'll use a Whale, pulling (or pushing, probably better) through another filter element, and finishing off with a Britta.

By the way, can I use a simple toggle switch to energize the Waterfixer a few minutes before I intend to use it, as a means of conserving electricity?

Re: Galley Foot Pump with some good pressure.

Roy,
Yes, you can use a switch for the WaterFixer unit to conserve electricity. I recommend 20-30 seconds to let the UV lamp warm up. Let me know if you have any more questions. j
