How to troubleshoot Low pressure on Cold Water

Low pressure is througout the house. I have a two story town home. Main water shut off valve is shared with others. I have a hot water heater with 2 valves for cold and hot. I have a tenant living in home now, and I reside out of state. I would like to have tenant troubleshoot before I call a specialist to come out and pay an arm and leg!

Welcome to the forums.

That's a tall order. It could be many things. I'll make a list.

1) Water service from street is iron and it's getting rusted shut
2) Same thing with plumbing in the townhouse.
3) If there is a pressure reducing valve at the main water service it could be malfunctioning.
4) Main shutoff valve is not turned on all the way.

Is the water service city supplied or well ?
How old is the townhouse ?
Do you know what material was used in the plumbing system inside the house.... copper, iron, plastic ?

Water supplied by City. Townhomes built in 1985. Not sure of pipe material. Is it possible we can troubleshoot at water heater? How or where can I look to see what pipes are made of?

The pipes coming from water heater appear to be copper

"Main water shut off valve is shared with others."

And there is no other valve to shut off just the unit without shutting off other units? Do the other units have trouble, too?

No just main shut off, unfortunately we have to let other units know when we are shutting water off temporarily. No I don't think ther units are having same issue. I've been having this issue for last 6 months and getting worse

First thing is to find out what the pressure is like in the other units. Asking to go in and compare would be best rather than just asking "how's it going?" because everybody is different. Some people like to take needle sharp showers.

Second thing is to dis-assemble the aerators in the sink faucet and wash them out. Even on city water, sand can collect in the screen and reduce flow. My shower head needs to be soaked in vinegar every year because calcium builds up. These are things that can make the flow gradually reduce.

I think after that has been done and everyone is sure your unit is the only one that has the problem, it is probably time to call a pro. Do you want the tenant changing valves or pipe? I don't think so. He does his best and accidentally floods the neighbor and who pays? Not him.

And if you don't want to hire a pro, then it is time for a road trip. Last I heard, the travel expenses for one trip a year to inspect your rental property is tax deductible.

Is this something a plumber can fix or other specialist?

I would think it would be a job a plumber could take care of for you.
