Since potential contamination from siphoning is the problem with the dishwasher drain line, this looks to me like it would be OK, but it also doesn't really seem right.

It wouldn't be installed according the manufacturer's instructions, but what exactly is the defect? Dissimilar metals in contact?

Brick two story semi in Scarborough On.
Buiilt in 1955
House vacant at time of inspection (don't know how long)
1/2 inch copper water supply line
1/2 inch copper distribution lines
Typical pressure in basement bathroom and laundry area

First floor kitchen pressure/flow was very low
Angle stops appeared to be open all the way.

Second Floor bathroom was the same.

I did recommend further evaluation by a plumber but I have not seen anything like this before.
Any ideas?

Appeared to be for 3rd floor baseboard heating. The home had forced warm air 22 years old. Finished attic had the baseboard registers supplied by this pump. Any comments on the pump. Also there was a electrical timer that was also feed off the water system. Any ideas what it was for? Going back for a radon pickup and will in quire with owner. Pump was off at panel.

There was a small brick chimney from the crawlspace up through the roof that I suspect used to exhaust whatever system originally heated the home. It was no longer used for any kind of furnace. A typical attic installed forced air funace was present in the attic with its vent through the roof as is typical. The remodeler had run the dryer vent through a transition box in the new laundry room up aluminum flex duct then into the small chimney. Then above in the attic they had installed a new natural gas water heater (new to the attic I suspect) and run the exhaust vent for the water heater into this same small chimney. I do not see this type of stuff around here much. Several questions. Is this permissible in general? Using the old chimney in this manner at all? If so, is it okay to use it for these two appliances together? The small chimney had no cap of any kind. I have some concerns that water could enter the vents of the two appliances. Also that wind could cause the appliances to either not vent well or even back draft on themselves, or back draft the water heater vent into the dryer. I did not like the setup. But not sure how to call it out or if I should. Inspected an 80 year old recently remodeled home today.
