Grey tank fills up quickly

[nomorervnv]

We also are 2 adults hooked up to city water. We just expect to dump the greywater tank every 3 days and do the black water at the same time. No problem. Does anyone advocate just leaving one or both valves open?

The only way a leak would end up in the grey tank would be a leaky faucet at he kitchen sink, bathroom sink, or the bath/shower. There is no other direct connection between the fresh water supply and the grey tank. Assuming no visible drips or leaks from the faucets, you are using the water. Only you can determine what is too much, and only you can control it.

There are many ways to conserve, this forum is full of ideas.

We always operate from our fresh water tank and onboard pump. "City" pressure will push a lot more water through the pipes than the onboard pump. That would be a good place to start to see is that makes a difference.


Good luck

When washing dishes, dump wash and rinse waters into the commode, vice down the drain. This helps clean the black-water tank, as well!

The sensors can give false readings. I agree with the other posts - what do they show after dumping? We have a simple solution RV - wash the dishes in a dish pan (not the sink) and dump the water in the toilet. It helps keep the black water tank clean. Don't take long or frequent showers in RV. Gray water tank will be full when water backs up in the shower drain. You can easily drain some grey water with a garden hose or in a bucket and dispose of it. We have a combination cap on the dump drain cap that has a fitting for a hose. Cost about $5.00. We also clean all tanks at the start of the season with the same solution used in marine industry.

Couple suggestions:
Sensors maybe giving false reading. Sensor cleaner may help as well as flushing really hot water through when hooked up to sewer. Our sensors start at 1/3 full when empty if not cleaned with sensor cleaner periodically.
When washing dishes- Put dish soap on dishcloth rather than filling sink with water. Wash all dishes then rinse all rather than individually
Use military showers or fill bucket with water and wash from bucket in shower.
Use shower facilities if available.

You definitely do not want you black water valve open all of the time. The liquid will come out and leave the heavier solids to build up in there. And I've had a major build up that I had to clear and it took hours to get it right. I do however leave my grey water valve open when I'm hooked up to a septic tank and running on shore power.

OP left the building on a long answer post to the question


we can go so very long on tanks. all about usage.

leak...leak into grey tank is not happening unless drip faucet or drip shower or you ran way too much into that tank and are calling that a drip


tank size. tank use. equals how long you got. most it is all about use.
3 people. 65 gal grey tank and we can go almost 2 weeks with showers. very easy to do. but every time that water runs, brushing teeth....long shower....that extra scuzzy pot to clean in the sink.....adds up very fast.

everyone has to 'learn their tanks' in a way.

If your tank is reading full and you aren't up to your ankles in water while you are in the shower, then I would say you have faulty sensors possibly caused by oil or grease.

This is really the solution to question of full tank. Carefully add water to grey tank while watching shower basin to see if it overflows. Make sure your connected to dump site. Friends had similar problem with black tank reading full in 3-4 days. The carefully exceeded the gauge display and managed another 4 days of regular usage. Depending on your gauge you may be able to reset full tank settings.
Btw technically your under sink doesn’t vent. It allows air to enter in with a 1way valve to allow air to follow water while draining. Vapours should not vent out of the valve.

We have a 70 gallon grey tank on our rig, but it kept showing full quickly. It was suggested to me that I fill the grey tank with clean water and a cup of Dawn. I did, let it sit for a few days, then took it for a drive then dumped. Sensors now show reality! Yea!

I agree except it is more like 3 days for grey and 4 to 5 days for black.

OP is gone.....bored to death!

I wonder about folks that have been on this forum, and others, but have 1 or 2 posts in 7-8 years? Then you never hear from them again....what gives?

Am I the only one that wonders about this??

I can only speak for myself on this issue...
I had health problems a bit after I joined this site in 2010 and had forgotten all about it until I received the newsletter (unsolicited) in my email box about a month ago.

Leave your gray tank valve open and don't worry about it. There are p-traps on all of your drains. Obviously, always leave the black tank valve closed.

Sounds to me like you just CONTAM your Gray w/ Black materials YUkkkkkkkkkkkk
