I would think this would've been discussed but I didn't find anything worthwhile after searching old threads. Does anyone have suggestions on how to increase the water pressure in the shower? Or is it just one of those things you have to accept as part of boating? I'm not looking for a jet spray or anything but mine is pretty slow to come out and it's not a matter of the shower head being clogged with mineral deposits.
 
There is a Jabsco accumulator mounted to the bulkhead in the engine space that evens out the pressure. I had to replace mine.

"Jabsco Accumulator tanks hold a reservoir of air and water down stream from the pump. The air acts as a cushion absorbing pump and pressure fluctuations, smoothing the flow and making the system quieter."

The pump is supposed to be a 3.3 GPM pump, so you might want to make sure that the PO didn't replace it with something that does not have the same flow.
 
Check the screen at your water pump on the discharge side. They can get pretty fouled which will reduce your flow. Mine actually has great pressure. I installed the Shurflo Extreme series pum
That has a variable flow so the pump isn't full plast all of the time.
 
Thanks for the suggestions...I'll have to check that all out. The water pressure is fine everywhere else, it's just that the shower is pretty slow.
 
Have you taken your shower head apart mine was full of un-disoloved water conditioner, that is one of the reasons I switch over to liquid. Also have you checked the screen on the intake side of your pump that comes from the tank?
 
I have a problem of bursts of hot water and then cold water. Any ideas how to get a steady temperature of water in the shower? (370 Sundancer 1996)

I had the same issue just a couple of weeks ago in my 95 370.

I took the flex hose off and blasted it with the hose. A bunch of stuff including calcium deposits blew out. I also cleaned the showsr head in CLR. Turned out that worked. I also needed to clean the screen on the sink tap. Problem solved.

This past weekend, everytime any faucet on the boat was opened, there would at first be water then the stream would die down and then come back. Almost like a pressure balancing valve was operating. This happened while connected to shore water, not on the tank. Dock pressure seemed ok. Is there a pressure reducer or balanicing valve somewhere I need to check/replace?
 
My water pressure from the dock is also very poor. Checked the water pressure on the hose leading into the boat and it was fine, but all three sinks had very little pressure. Opened the engine compartment and did not see any kinks in hoses (in fact the looked great). What should I do? (and spare me the jokes about using Flomax...LOL). Thanks guys!

It sounds like you guys have very similar problems. I would try replacing the pressure regulator that you hook your shore water hose up to. It will probably be a Shur-Flo one that looks like this:

This unit will decrease your dockside pressure which can approach 100+ psi to a relatively safe 30-ish psi.
 
I hope you are right Todd! I plan to do that this week. If it works, that will be a cheap fix to a problem that drives my Admiral right up the wall. Want to keep her happy ; )

How hard is that to change? Mine has a slow leak that ends up draining out in to the "trunk" and then on the swim platform. It'd be nice to have everything stay dry. Do you just undo the 4 screws? I assume there is some slack/service loop in the hose on the back side of the fixture. Remove / cut off the old fixture and connect the new one? Is it a barb fitting with hose clamps or something more solid like a screw on connection?


Thanks
James

The biggest problem with changing the SureFlo adapter is that SR left ZERO/NONE/NADA extra hose to speak of to do the change out. You would think they would think the damn thing is going to fail at some point and leave an extra foot of hose to make the change out more user friendly. NOPE! Just damn.

James,

The locker that houses mine is on the starboard side. There is an access panel there right next to it. I have to reach inside and remove the clip on the snap -on connector to seperate them. Then unscrew those 4 screws and it will come out. There is a snap-on connector screwed onto the back of the regulator that you will need to unscrew and re-attach it to your new regulator. Make sure and use teflon tape or similar thread sealer or that leak will remain!! If you can see the back of yours I would do an inspection first to see where the leak is coming from. It may just need to have the hose removed and reseated in the connection. I had a leak like that in my bilge once and that was all I had to do to stop it.

Good Luck!!
