Water Tank location Regal 3360

[lance_3360]

Hi, I have some issues with the water system.
Water pressure is ok, but then when the pump kicks in the pump does not hold up the pressure and it drops until a small stream is coming out of every faucet. I think Ill check the pump first but what I really would like to know is water tank location.

Not familiar with that model - but where is your filler?

Most of the ones with the filer in the bow by the anchor locker are under the floor in the berth. You may have access to the filter via an access panel under a berth seat. Most of the time the filters can be removed to test pressure and cleaned.

If it's rear mounted you should be able to chase the tubing. If it's somewhere in the middle, i'm no help.

Hoping someone with experience with a 3360 chimes in.

Did you check the strainer which should be just ahead of the pump?

Agree, if the pump has full pressure when first turning on a faucet then drops to a dribble sounds (when you can still hear the pump running ?) like a up stream pre filter. We have also installed a activated charcoal filter on the pump outlet to get rid of the smell in the ice maker, faucets, etc. If you have a downstream activated carbon filter that might be the cause and time to change it as well. The slight surge in flow at a faucet is probably due to the hot water heater tank being like a pressure accumulator ( a capacitor in a electrical circuit) and assist the flow for a few seconds or so? Dont think you need to go to the potable water tank unless the pre filter is located at the tank?

Thanks for the tips, I´ll check the filter of the pump tomorrow. Its on the firewall in the engine sump / bilge at the back of the boat.
But I have still no clue where the fresh water tank is. There is a bed in the bow of the boat - maybe under the matress?

Don't look under the mattress, that's where the dragons hide!

[lance_3360]

hahaha ok,

the problem was the filter in the pump. Its on the firewall in the engine sump next to the battery charger.
It was totally cloaked with scale.

Per your OP you indicated a small drip of water was coming out of all the faucets? That would mean the faucets are leaking? probably you meant when turning on any faucet you had good flow for a few seconds , you heard the pump turn on, then flow just reduced to a slow drip? i ,may have misinterpreted what you were saying? Glad you solve your problem. I would be careful as to what and where you fill up your potable water tank from, probably crud or a lot of calcium in your water source? Our vessel still has the original pump pre filter installed (18 years ago). Only problem was the pump itself failed last year, just worn out, my son's took too many long showers .

hehe, glad to hear how long it lasts
Yes, its the water in croatia very chalky etc. not only an issue for boats, all the house plumbing of the locals is also affected.

Interesting! If you want to just clean out the pump pre filter just take it out, buy some white vinegar, fill up a small bowl with it and put the chalked up pre filter into overnight . Dont know what a new pre filter would cost you where your located but white vinegar should be fairly cheep? My mother and grand mother made a lot of sauerkraut with it:)

The pump is doing fine, but i still wonder where the water tank is.
I checked what’s under the bed in the bow. Here is the bow thruster nothing else. I still have no clue wheeee the tank could be. Any ideas?

Find the potable water fill connection on the outside of the hull. the tank should be some where below it on the inside of the vessel!

[lance_3360]

The strange thing is that it is so narrow and behind the firewall.
I can’t see where the hose is going.
In the shower there is no screws or anything that could be opened.

So on my 35SC (which is the same hull as the 3360) was under the forward berth. In my 3060 it was under the cabin floor which the only access was under the stairs under a access cover. The issue there is you really can't get to the water tank, in order to change it on the 3060 you had to cut out the fiberglass cabin floor to get to it. Hopefully its somewhere accessible for you. It should be about a 30 gallon or more tank so it will be pretty big somewhere. Under the aft berth maybe?

[lance_3360]

hi, ok hmmm thats very strange. I looked under the front berth and there is only space and the bow thruster.
The water inlet is in the back portside - see picture. I checked everything but I really have no clue where it could be. The overflow valve is at the very back on the same side. Inside the engine bay I see the grey water tank - could it be a combined tank for grey and freshwater?

[lance_3360]

I checked the input and the hose again, followed it to the engine bay. It goes through the firewall right in the middle of the engine bay between the two engines...

[Chris_in_Texas]

Under the mid-berth then maybe?

[lance_3360]

what is the mid berth excactly? is it the dinette, sleeper couch or in the back of the cabin? sorry for that rather stupid question...

[Chris_in_Texas]

Yes the seat or bed in the back of the boat, under the helm station. There should be access panels under there somewhere in the floor and a bilge pump for sure. The shower sump might be there as well. Or its under the stairs possibly as well. There should be a small access panel under there. I haven't owned a 3360 but the 35SC has the same hull, and many of the parts are the same between the 3360 and 3060 which I had as well. Hopefully some of the guys with a 3360 will chime in.
