Hi, I've realised over the last couple of days that the water pressure in my house has dropped. It's dropped for the hot and cold all around the house. I have one main stop cock which hasn't been touched (as it's under the floorboards). I have a combi boiler and no water tank. I'm pretty sure all the taps feed directly from the mains - bar the hot water.
The toilet cistern is making a pretty loud noise when it is flushed as well. Can anyone help?
Thanks

Sorry for the delay. Are you on city water or a pump? Let me know, Tom

Do you have a water softener, or whole house filter? Also, if you are on city water, do you have a pressure reducing valve in the system? Let us know and we will try to help out.

Hi, I don't have a pump, a water softener, or whole house filter. I'm connected straight the mains. I'm getting the feeling this is a USA based site. I'm in the UK - it therefore may be difficult for you guys to answer. If that's the case, thanks for your effort and apologies for taking up your time.

Hey! Don't give up on us yet, We answer questions all over the world. Plumbing problems know no nationalty. First, a little information. How old is your house? What type of pipes do you have? Has there been any work done outside on the city main? Is there a PRV ( pressure reducing Valve) installed on your water service? Back to you, Tom

Lol, sorry Tom.. You're right - I should have a little more faith.. The house is around 80 years old, and it has copper piping. I checked to make sure there was no work going on close by on the city mains. As far as I'm aware there isn't a PRV installed on my water service. I did a lot of wok to the house when I moved in about 10 years ago - many of the cental heating pipes were changed. I also installed a new kitchen and new bathrooms. Zahid

Do you have a garden spigot, how is the volume from that spigot. This is most likely not a pressure issue but one of volume. If you have that spigot you can test the pressure by connecting a gauge to the outdoor spigot.

Yes I do have a spigot (I'm assuming that this is called a tap in England). I don't have a gauge but can try and get hold of one to check the pressure - thanks. I'm not sure it's about volume given everything was OK up until a week ago.

Voume can drop in an instant, especially if it is due to debris clogging a main valve. I assume you have asked your neighbors if their volume/pressure is still good, right? Also, ask your water company or supplier to check your pressure and volume, usually done in a day for free.

Yes, I've asked my neighbours - they haven't noticed a difference. I'll do as you suggest and give my water supplier a call and ask for the pressure and volume to be checked. Great, thanks.

Great, Tom and I will be here when you get back.

Turn on the garden tap and let us know if you have a strong stream. When we get pressure back then we'll address your noisy toilet. Back to you, Tom
