Fresh water tank dump valve

[Old Grape]

My previous coach (2006 Winnebago Tour) had a fresh water tank dump valve just like the black and grey tanks. It drained directly to the ground. My Aspire does not have that. It only has the small low point drain line as far as I can find. Am I missing something? is there a larger valve hidden somewhere that I have missed? If not has anyone retro fitted a larger dump line and valve on their fresh water tank?

Neither of my coaches have much more than a 1/2 or 3/4 drain valve on the freshwater tank.

Clean water generally doesn’t need much bigger although it does take longer to drain a fuller tank.

Waste tanks have big valves because the water can be (excuse me) “chunky” - something that would quickly clog a smaller valve.

When plastic tanks are used in tight spaces, the larger the port in the tank for the valve to fit, the riskier the chance for it to leak.

There is a dump valve under the fresh water tank, in front of the duals on the passenger side of the coach. Small valve so don't get in a large hurry.

Yep, my old Suncruiser had a nice dump valve too. 1" pipe thread. Unfortunately, Entegra does not have that. They use the smaller PEX line for their drain valve and generally tee it in with the water pump pick-up line via a 3-way valve that also lets you drain the water pump line. It works but it is real slow. There's times when I've shut off the water, opened the gray tank dump valve and ran a sink faucet with the water pump to speed it up. Still not as fast as that larger Winnebago dump valve though.
