Low pressure fresh water system?

I generally push beer at a little < 15 psi, should be adequate for the galley sink. But, I was thinking. . . isn't your tubing rated? There should be specs either on the tubing itself or on the reel at the store.

I feel that I push beer out much harder than that!!! Then again when I'm pushing beer out, I've been drinking and my judgement is altered.

How did you measure that pressure?
Sorry, couldn't resist.

Any idea what kind of pressure a foot pump creates? I had one on my previous boat and it could move a serious volume of water quickly but not at much pressure.

Whale Foot pumps are rated for 10 feet max. water column or about 4.3 psig.

Don't you have a pressure regulator on yours? Of course it depends on the diameter of the hose.

If we are going further down this path, no pressure regulator, still originally equipped with two ball valves below. Keep in mind that length increases resistance too. Seems like you are confusing ID with OD.

I might be going off on a tangent. . . But, I want to check and probably clean out the water tank on my 1974 boat. Any helpful tips on technique and cleaner will be appreciated. The tank has an 8x4" access port on the top with probably 10 bolts. I'd guess the tube out, near the bottom, is ~1/2" dia.
