Title: Water Tank Replacement
Post by: Herodotus on November 10, 2010, 11:51:58 AM
Upon attempting to fill up my aft water tank, I discovered (...how the surveyor missed this, I have no idea) that the water tank is cracked so tht it does not carry any water. Whatever water I pumped into the tank (10 gallons) ended in either the bilge or soaked through the aft cushions.

Has anyone ever had to replace their entire water tank? I'm at a bit of a loss here.

Thanks,

H

Check this thread out:  http://c34.org/bbs/index.php/topic,5089.msg31162/topicseen.html#msg31162

Just did a search on aft water tank and a few hits came up.  This seemed like the best.  Good luck.

H : Call Catalina Parts and and give them the year of your boat and find out the price of a new aft tank.

I'd also call the surveyor and let him know your problem.  You aft tank has to come out of thru the aft cabin.  You'll have to take off the port side panel in the aft cabin off and then the aft panel. 

While you are looking at the fuel tank you might as well pull the fuel pickup tube and make sure there's no screen on the hose end. 

Before you install the new tank look at the steering quadrant and inspect the cabling for any "fish hooks" (broken wire strands).  Also you might want to change those bronze pulley idler pins and replace them with stainless pins (call Edson) and adjust the tension. 
From the age of your boat you need to inspect the scupper hoses and replace them.  Also inspect the rudder packing gland.

Just a few ideas while you have things apart.   :idea:

You might also check with some of the plastic shops in the area and see if it could be "welded".  I know this is common for motorcycle fairing repairs and my local plastic supplier just started offering the service.  I have a small crack in the drain fitting that I plan to have welded.

H : Rick has a point.  You need to remove that tank and look at the split/rupture.  Then it's up to you whether you get it repaired or just go with a new one. 
I'm sure that $$ will also be a deciding factor. 
I'm sure after you go thru all of the effort to remove that tank you don't want it to leak again.   :cry4`

not sure if it is the same material but a lot of auto collision centers are now advertising plastic bumper repair.  Might be another source of repair.

My marina neighbor repaired his water tank with JB Weld.  They make a putty in a tube that is easy to work with and tough as nails.  His leak was in one of the seams and an easy fix.

Just climbed out of the aft lazarette and am filled with fiberglass spurs.

Searched for a part number for the water tank - no avail. Maybe it's written on the front of the tank?

This crack...let me explain it a bit better. It's as if someone ripped the water tank apart, cutting through the top board and then running diagonally down the aft face.

Round #2, fight! I'll keep all updated.

Sorry to hear about the extent of the damage.

You most likely will NOT find a part number on the tank.  Here's the parts list:  http://www.c34.org/parts.html  (I searched for +parts+list)

Please take the advice earlier offered:  call Catalina Yachts.

Peggie Hall has also repeatedly suggested that Ronco Plastics offers very good tanks.

If it's a plastic tank, you can buy an identical replacement from Ronco Plastics.
http://www.ronco-plastics.net/marinetanks.html
Ronco has supplied all the water and waste tanks for Catalina for several decades.  Give 'em the boat year and model and which tank, they should know which is the right one. Buy direct and save the markup Catalina puts on it.  

Btw...they show 400+ tanks in their catalog, but any that are still OEM proprietary won't be there. So depending on the age of your boat, it may or may not be in the catalog. However, that doesn't mean they don't still have the mold and know which one you need.

Peggy, you are a mine of useful information.

Re the crack: To a Canadian, this sounds like ice damage. Was the boat in northern latitudes at all?

H & Guys : For the 1987 C34 the Part # is 60174 (stock# B182) for the aft 42 gal water tank and it is listed for $68.30 !! 

I got that information from the 1995 C34 parts listing that I posted on our C34 web site.  I believe the price has changed, but doubt if the part or stock #s have changed.  A thought

B182 is Ronco's mold #.  It may be in their retail catalog.  Check price and shipping with them before ordering.

Dang, talk about inflation.  The price increased by $232 over a 15 year period!!   :cry4` :cry4`

Y'all are absolutely amazing! I'm heading out to the boat tomorrow with these replies printed.

Although I do not know for certain, I doubt this boat was up north. The PO did not know much about the state of the vessel, though I'm pretty amazed this wasn't noted on the survey.

I called CD. Because this tank will be a custom job, I will be unable to return it if it does not fit the compartment. Therefore, I need to take some measurements. At $299.99, need to be pretty sure of those dimensions.

But Ronco plastics. Roger that.

Thanks everyone!

H : I have a sheet from Catalina Parts that shows the 42 gal #60174 (#B182) tank dimensions as :
46" wide  18" deep  and  13" high.  Hope this helps

I have questions:

Where was the crack--top, side,?

How long ago did you do the repair?

You see, the problem with trying to repair polyethylene is, it can ONLY be heat welded, blending new PE with old to create a continuous surface. There are different types of PE--linear high, medium and low density and cross-linked--which is why the shop needed a sample. (Fwiw, water and waste tanks are linear low density PE).  There is no "sealant" that will bond to PE permanently.  But even heat welding is iffy...' cuz filling a tank tries to push the edges of the weld apart again...and eventually succeeds unless the crack is in a location that isn't subject to much stress--for instance, around a fitting.   So I'm very curious to know where the crack is and how long the weld has lasted so far.

It's certainly worth the risk to try it with a water tank to save $250,  but I wouldn't risk it with waste tank...'cuz if/when the weld fails, a  19" crack re-opening is gonna dump the tank!

Not to nitpick...but how long is "some time?"  Several months?  A couple of years?  And...do you fill your tank or try to keep the level below the crack?

I'm not trying to pick on you...just trying to get as much detail as possible.  Fwiw, there's a guy on one of the houseboat sites who's used JBWeld so many times to plug holes in his aluminum waste tank that the tank has to be more JBWeld than aluminum by now...and amazingly, it's still holding after more than a year! 

Btw..."gray water" is galley, bath and shower water...sewage is "black water."  I wouldn't recommend trying to repair either one.

Decision has been made. New water tank from Ronco will be ordered next week along with Edson order.

Thanks everyone. Seriously, by the time I get this boat set, it'll be just like a brand spankin' new boat.

Following Peggie Hall's advice, I ordered the water tank from Ronco Plastics - #B182-C. They were more than helpful and quite accommodating. All together, I received the tank for $250. Thanks again, Ronco.

Installed it this morning...missed the hose that connects the water tank to the plumbing....sigh. Water pours in. Noticed the hose was never clamped on the old WT either.

New WT works great, no problems yet.

Top: Save your fittings. The new WT did not ship with them.
