Why Richmond Homes Trust Our Brassware
Calibrated control to keep street water surges from hammering your pipe joints.
Protects flexi-hoses from bursting
High pressure stretches braided hoses on basins and toilets until they snap; dropping the pressure removes that strain.
Silences rattling pipe runs
What causes that loud bang when a tap closes? High-velocity water hits a dead end; slowing the pressure stops the shockwave.
Saves litres on every shower
By trimming surplus pressure without changing the shower feel, you consume less heated water every single week.
Questions about this service
What is normal domestic water pressure in our area?
Most Richmond homes receive between 2 and 5 bar, but low-demand periods at night can cause street pressure to spike higher, which strains internal valve seats.
Will a pressure reducing valve make my shower feel weak?
No, we set the valve to roughly 3 bar, which is the exact pressure domestic shower mixers are engineered to work with at full comfort.
How often does the internal filter need cleaning?
The built-in stainless steel mesh screen catches street grit and only needs a quick rinse once every two or three years during routine servicing.
How We Carry Out Valve Work
-
1
Static pressure measurement
We screw a test gauge onto your outside tap or washing machine feed to measure your incoming static bar rating.
-
2
In-line valve integration
We cut into the cold incoming line after the stopcock and solder or press-fit the brass regulator body in place.
-
3
Dial adjustment and balance
We turn the top hex adjustment screw until downstream pressure settles at an optimal 3 bar under both static and flowing states.
Our Workmanship Commitment
Every valve, cartridge, and fitting we supply and install comes with a twelve-month installation assurance. If a joint we fitted weeps or a valve fails to shut off as agreed, we return and put it right at zero cost to you. Pricing & payment
What Local Residents Say
The quarter-turn lever action on this isolation valve is noticeably smooth. The courier arrived on Thursday morning, and I paid cash on delivery right at the hallway door. The parcel was a sturdy corrugated box with the valve wrapped in paper.
Marcus E., Richmond, GBThe 15 mm compression elbow fitted neatly onto the copper pipe, but the van driver missed the morning window and arrived late afternoon. I had to wait in all day. The fitting itself is fine and the threads are clean.
David W., Twickenham, GBI ordered this ceramic tap cartridge for my father's kitchen basin after his cold tap started dripping constantly. The spline count matched the photo, though I wish a spare retaining grub screw was included in the packet. The tap shut off completely once fitted.
