Hi,
I recently put in a new boiler (oil) and replaced my hot water heater. I replaced the plumbing exactly except I did not run the hot water pipes through the new boiler. Everything works fine. However there's a noticable drop in water pressure now (that did not happen before), whenever any two facets are running in the house. When this is happening the second facet just gets a dribble of water. Can anyone offer any advice?
Many thanks.

And the cold water is fine?
If the cold water is also affected and you live in Maplewood, it could be a coincidence that the town's pipework is being done just as you're fixing your plumbing.
Also, check the main water valve. You may not have opened it all the way when you were done working. I've done that and the pressure was much lower -- until I gave it a few more turns.

Do you have a pressure reduction valve on the house side of the meter? Just a possibility. |

OK this is kind of dumb but it did recently happen to me so it's worth checking.
Make sure your master valve is all the way open, and check any valves you may have between the lead into the house and the water heater.
It is possible it got turned off in order to do the work, and when turned back on, was only opened partially.

wnb,
Did you read my post above? I did the same thing!
But, yes it is kind of dumb.

Spiderman. open the faucets, go down to the work area and listen for the spot in the piping where the hissing noise of the water running is the loudest. Sometimes the restriction will cause a telltale whistling noise. |

Nice thoughts, but the faucet runs fine if only one of them is on.
The obvious answer is the pressue is dropping because more than one faucet is on at the same time. However, I know for certain this did not happen before I installed the new boilder and water heater. I would get decent pressure even if two were on at once.
I copied the exact plumbing as it was originally, except for the line going through the boiler - I decided not to put the hot water line through my oil boiler.
Everything is fully open and no hissing sound.
Thanks for your ideas.

Well, then it sounds like a plumber plumbed in a flow problem.
If the pipe sizes are not large enough at the root of the run, then you will have exactly this problem at the branchs when the fixtures are turned on.
In homes, most end runs to fixtures are in 1/2 inch, and they are fed from a 3/4 inch pipe, and that is fed from a 1 inch pipe, and your street mains get larger. This allows for proper water flow at the fixtures when all are on.
If you have 2 fixtures feeding off a single 1/2 pipe, you will have this problem.
Later,
George |
