Welded plastic water tank

[Badsanta]

I'm on the east coast of virgina and looking for a manufacturer of watertanks. Ronca wont fit so I need a custom tank. I have found sources online but looking for real use info.
Many thanks

This is your best source: Triple M Plastic Products Inc They've made a lot of tanks for people on the dozen or more sites on which I've posted, and I've yet to hear anything but good reports.

Weirdly, Triple M Plastics has a .us URL rather than a .com address. So the correct URL is Triple 'M' Plastics

Thanks for the lead peghall.

Thanks for updating the URL...It worked the last time I tried it, but I should have learned by now to check 'em all at the beginning of every year...'cuz half of 'em for my own book don't work any more!

Both of these sources claim custom capabilities. I considered it and instead found that Plastic Mart has a catalog of special non-rectangular 'standards' about 40 pages long. I have had trouble re-locating this download. You may have to call and ask for help locating the data. We were able to find a suitable odd shape to work for way less than custom. I made a cardboard model from their dimensions to make sure it could work. They will install any fittings you need anywhere you want.

Fwiw, Boat Tanks and Plastics Mart are both retailers of Ronco Plastics tanks ...at a pretty good markup too, with a downside of pre-installed fittings. Ronco does sell direct and also installs fittings in the sizes and locations specified by the customer when they make the tank: Ronco Plastics Marine Catalog

Yes I've made cardboard mockups and spent hours on the ronca site and havent come close yet. I dont think I've posted to dozens of sites yet. Thanks for everyone's help. But don't think I can afford a custom made rotomolded tank but hopefully a welded one. I was thinking closer would be less shipping cost. But I'm sure that shipping is little of the cost.

[peghall]

A welded tank from Triple M should run about double the cost of a (not custom) rotomolded tank. Most of the price of a custom rotomolded tank is the cost of making a mold.

Btw...you DO realize that any of the Ronco tanks can be oriented in any direction, even stood on the point of a triangle as long as the tank is support...'cuz there is no top or bottom of any tank until the fittings go in, and you decide where they go.

I second TripleM for a source. I have two tanks made by them - spot on to my dimensions.

[Badsanta]

Yes. Ive got several from them. But thanks for the info.

Also, investigate Dura-Weld.com. I had excellent results from them this past year. Custom 50 gal H2O with two fill connections, one goes-out and one vent all located in the proper location.

I'll check them out. Thanks
