Installing Shields White Hose - Toilet Rated

[spartonboat1]

I sprung a leak in my output hose attached to the Jabsco Toilet output fitting, which is a Shield's brand White hose, "Black Water" rated, [ SHIELDS VAC XHD SERIES 148 ]. No doubt I caused the leak while trying remove the hose from the toilet output fitting.

So I bought the same grade and size (3/4" ID) of Shields hose at WM. However, installing the new hose was a non-starter. I tried several fluids on the fitting, including the trusted Dawn detergent- no joy! I tried heating the hose with hot water from the spigot- again, no joy.

So the hose came home with me.

I setup a 10 qt pan on the gas stove and started heating the water. As the water heated, I tried installing the hose, at variously hotter temps, but without success. So finally the water neared the boiling point and I left the hose immersed for a couple minutes and it became floppy, compare to its room temperature state. I doused the fitting with some SoftSoap for slipperiness, pushed the fitting into the hose and Voila!- on it slid right on and could be rotated to what I thought was a best angle.

Notes on the fittings- the toilet output fitting has a barb around the end. However, it is a smooth fitting into the hose originating from the Holding tank. I think the hose will go on the smooth fitting far easier.

So my solution is- immersing the hose in nearly boiling water relaxes that brand and model of hose sufficiently well to install on the barbed fitting far easier.

Hose like that I just use a heat gun till it gets soft push it on and clamp it right away and you're going to have to cut it off.

I did something similar; I boiled water in the boat's microwave and used that to soften the hose. That stuff lasts a long time, but it is a pain to install. I wonder what they do at the factories that use it.

Yes, true, cutting off the original was the required technique!
