I would link to back of sink were it feed s the outbuilding toilet fills up ok but slow but washing machine not running problem due to water pressure

Is the 15mm pipe to the house connected to the cold mains supply, or a gravity-fed supply?

Customer: replied 9 days ago.
cold mains

Sorry for all the questions - I should also have asked you the distance from the house to the outbuildings.

Customer: replied 9 days ago.
pipe to outbuildings is about 5 metres

I would first of all change the supply to be 15mm copper or Hep2o. Is it currently in copper? How many twists and turns are there? And what type of isolating valve have you used at each/either end?

Customer: replied 9 days ago.
15 mm plastic pipe buried under cabin stop valve at house end. about 4 90 Dec bends but no twists
Customer: replied 9 days ago.
I live in bungalow and kitchen is at opp end of house to the main water supply

Apologies -I meant from 15mm copper to be 22mm.

Customer: replied 9 days ago.
ok I was hoping to leave the pipes as they are so hoping to just add a booster but do you think I need to replace all

One moment - I'm typing you an answer...

The bore of plastic pipe is significantly narrow than copper.
Was the pipe ducted, or could it have been crushed at all?
Do you know your mains cold flow rate at the house end?
What type of stop valve is at the house end?

Turning to your original question, there are three ways of boosting the supply (in addition to increasing the bore size).

1. A break tank in the outbuildings with a pump on the outlet;
2. A pump on the supply to the outbuildings, but you would need permission from your water company if you want a flow rate of greater than 12 litres/minute.
3. An accumulator.

the pipe had ducked don't think it was crushed .the valve is screw type don't know water flow rate all I need is water flow to increase for washing machine hope that helps with answer

You can easily measure the flow rate with a bucket and a wristwatch.

If you do that at the house and then in the outbuildings, then we'll have numbers to work with. Without them this is guesswork.
