test water disposal

[Anonymous]

Just wondering what others do to dispose of the water from their test tanks/barrels?
Thanks

I empty on the lawn actually. Modern type 3 oils and frequent changes does not kill anything so far……….

Waste oil is different……….it goes to the proper disposal point locally of course.

It’s the exact same stuff that normally goes into the lake. Just highly concentrated. In spite of all the angst by some people, the lake lives on. OK, let’s admit, high concentrations might have some effect. A controversial subject.

Bob Kerr Tools, you can get test tank filters, I"ve had one for years, they work. Also try bilge pump filters. Make your own if you want to save some money.

I often just use the barrel for first engine tests prior to a boat test or to flush motors for several minutes after brackish water use.

I change the water frequently so oily residues do not start to build up.

I also use the oil absorber (sheets or socks) since the unburnt oil stays on the surface. These are easier to dispose of.

Normally I can then dump the reasonably clean water on the lawn afterwards.

I have also mixed dish soap into the barrel now and then and then dumped the water down the toilet bucket by bucket.

Presently, I only use a 32 gallon plastic trash can for my tank.
The water hose in it keeps a steady flow and the excess
with any oil flows down the grade onto the lawn with no
ill effects. My neighbor is so – environmental conscious –
that he puts Dawn Dish Detergent in his tub to break up
the oil – then empties it onto his grass with no ill effects.

and as Frank says – this is a personal choice as well as very controversial.

I just picked up a 100 gallon metal horse trough tub from the trash
and it needs a few small holes in the bottom fixed. Then I can connect
a water hose to it to empty into the woods. (it will make my mind feel better).

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

I let it sit for a while after I run some motors, skim off the top oil buildup, throughout the summer, dump the rest on the lawn. The oil I drop off at my local dump, along with any used gear oil, fuel, etc…. that is no good. They take it for free there.

Hmmm I don’t have that problem, as I tend to run only above water exhaust motors in any sort of tank. The water doesn’t stay as pure as from the tap, but it’s not really all that cloudy either. I’m sure there’s some level of motor feces in there due to mixer valve drip or lubricant seepage from the gearfoot, but obviously much less than newer, higher powered engines with underwater exhausts.

For larger motors with underwater exhaust, I prefer to briefly dry fire them on a stand or cart, then fine tune it on a boat and pollute the water in that manner. Most every motor I have, the first extended run it ever gets is on a boat. Funny, but in a previous life I’ve tried running them for extended lengths of time in a tank, but I never made any headway, it seemed like every time I shut the motor down, I was right back where I’d started…..

Best,
