Hi, would like to get opinion.
Recentli my contractor did install one way valve upstair bc my water pressure is low at upstair. After the installation, i notice the meter(Marked red square in picture) keep fluactuating forward and backward even though no usage at that time.Is this normal? Thank you. Attached thumbnail(s)

QUOTE(vin6 @ Oct 13 2025, 09:23 AM) how does a 1 way valve solve pressure issues? The 1 way valve is from main pipe bypass the water tank. When there is no water from main pipe, water from tank can be used. |

Hmmm did i get the wrong terminology?Isnt it called 1 way valve?
Anyway the idea was to increase water pressure in bathroom by directing mian water pipe to bathroom.If there is no water from main pipe,water from tank will flow into bathroom. Sorry for the confucian. |
