From what I can tell looking online, although the TC5 doesn't come with fill hoses, the hose kit they "recommend" getting contain 3/8" diameter hoses. I recently put in 3/4" hoses for my old Whirlpool washer and wonder if I will have to replace them now that I hope to get a TC5. Does anyone know why Speed Queen would sell such narrow hoses? Are they for some reason better for this machine than the 3/4" ones?
Thanks
 
Fill Hose Size.

Hi, I dough that your hoses are 3/4" inside diameter, the SQ hoses are 3/8" inside diameter, which is plenty large enough. 

 

You can of corse you the hoses you have now on a new SQ.

 

3/8" ID hoses are less expensive to make, they do not waste as many materials to make, they are plenty large enough and they are less likely to burst.

Looking around on the linked page, it would appear the 3/4" is an outside dimension, with most likely 1/2" ID. Stepping down to a 3/8s ID would only be a small decrease and unlikely to be a problem like John said.
 
did my eyes roll out loud again?

are we still on this one?...

have you ever considered buying several hoses, and hooking up to a meter, to measure how much water per gallon each one gives you.....

plus if your machine has a restrictor in the valve, like many Speed Queens have, it ain't going to matter anyway...
 
A larger internal hose diameter has more surface area to have pressure against it. For a given wall thickness a smaller diameter will have a higher burst pressure.

The stainless braid on the outside sure looks pretty, but it likely does nearly nothing to make the hose more burst resistant. Best thing is does is offer abrasion resistance. The real strength of the hose comes from the plastic fibers that are molded into the rubber. While talking about hose failures remember that a hose almost never fails along its length unless it was damaged. They blow out of a fitting at the end. Quality of construction is far more important than pretty stainless braid. Like the nearly worthless gold TiN coating on box store drill bits, stainless braid sells a lot of hoses too.

In any case hook up a 4" fire hose to your machine and it will still take the same time to fill.
 
washing machine hose diameter

Thanks for all the responses. I would like to be able to turn off the faucets after each use but I have garden valves that require so much turning (besides the fact that the cold doesn't even completely shut off) and I was told by my plumber that it would cost many hundreds of dollars to switch them out to the proper type of valves. So I didn't go ahead with that but I did have him change out the hoses because they had been used for over 20 years. Since I will not be turning the water off between uses it is very important to me that the hoses are strong. They are made by wolverine brass. Do they not make quality fittings?

I had actually called in the plumber because I had tried and was unable to budge the garden valves and I wanted to make sure I had operational ones so that the installers could remove my old machine and hook up the new Speed Queen. As it turns out, the valves could be turned (it needed a lot more strength then I was putting into it - I didn't want to risk breaking something.)

I finally got an answer from someone at Speed Queen. Per the products installation manual, the hoses must be a minimum of 3/8 inch inside diameter. I was told that the reason is because smaller diameter hoses will cause longer fill times which will cause errors if the machine does not fill within 30 minutes. This sounded strange to me because using .27 inch diameter hoses could not possibly make the machine fill time be anywhere near 30 minutes. They also said that a longer fill time keeps the fill valve energized longer and will wear the fill valve out quicker than intended. When I wrote back expressing my doubts about this they said that this is what their engineers are telling her.

Does this response really make sense? Based on what SQ told me, would you change out these nearly new .27" diameter hoses for the 3/8" ones they recommend? The nearly new hoses cost me $35 per hose (the hose alone besides the installation) so I don't want to discard them for no reason.
Thanks so much
 
hose diameter: @ kb0nes

Thanks for your response. Unfortunately I don't understand some of it! :) When you say, "A larger internal hose diameter has more surface area to have pressure against it. For a given wall thickness a smaller diameter will have a higher burst pressure" are you saying that a smaller diameter hose will be less likely or more likely to burst compared to a larger diameter hose?

Also you mention that when hoses fail they usually "blow out of a fitting at the end". Are there signs one can look for/ can one see in advance that something like this will happen soon? You mention quality of construction being very important. Are you familiar with products made by wolverine brass?

Thanks so much
 
We replaced the ss hoses they gave us with the washer in 2014 with some really nicely made 60" ones. Like you said one of the old ones was leaking around the crimp at the end. I probably could have put a hose washer in it but I didn't trust it so we have a Ace Hardware 5 blocks away and everyone there is friendly and knows their stuff. The new ones were like 15 each but the ends are much better made with thick rubber gaskets and a brass center section. I like to have enough to be able to pull the washer out and run it when I'm tracking down issues. They have 3/4 ends but the rubber under the SS braid is really thick too. I had ok rubber hoses before on the old machine and one started leaking so I bought some of the thick red rubber washers for it and it was fine for a few years till we got the new machine.
