My tankless water heater was discharging water randomly. I had no idea what the issue was. But Sergio came by ASAP and helped diagnosed what could be the issue. It was determined that my water pressure regulator was broken and the water pressure was 140 psi. He replaced it with a new one the same day within an hour, and lowered the pressure to 50 psi, and no more water is discharging from my water heater anymore.Read review on Google
RESIDENTIAL PLUMBING / SHOWER FLOW
Low Shower Water Pressure
A SHOWER THAT LOST ITS FLOW?
A sudden change in shower flow can make a daily routine difficult. We check whether the restriction is at the showerhead, mixing valve, or a shared hot or cold supply before recommending a repair.

UNDERSTAND THE ISSUE
Low Shower Water Pressure: When To Call A Plumber
Mineral buildup or debris can limit a showerhead, but weak flow may also come from the valve, cartridge, a temperature-balancing feature, or a supply issue. Note whether the flow change is hot-side only, affects other bathroom taps, or began after plumbing work. A symptom in one shower does not establish a whole-house pressure failure.
Residential Plumbing Customer Reviews
My water heater stopped working and what did i do, i let my fingers do the walking on Google & did I get lucky. I called Best Quality Plumbing & Sergio answered on the first ring, told him the problem, he gave me a very reasonable price to come out and take a look and I was right, I needed a new water heater and he not only went to Home Depot to pick one up (it was Saturday & wholesale plumbing stores were closed) and within two hours, my tenant was happily singing in the hot shower. I have added Sergio to my contacts and he is now on my go to list.Read review on Yelp
Sergio gave me a good quote for three different jobs. He was on time and wok fast. He change the water heater, water valve for the washer machine and the water pressure regulator.Read review on Google
WHAT WE'LL CHECK
Your Low Shower Water Pressure Options
We ask when the shower changed and compare hot and cold operation with nearby fixtures. The showerhead, handle, trim, accessible valve details, and any recent work are reviewed where possible. If several fixtures have changed at once, that pattern can point beyond the shower assembly and guide the next inspection.
Service The Showerhead Or Valve
A local restriction or worn cartridge may be addressed at the shower assembly when the rest of the home has normal flow.
Trace A Shared Supply Concern
When multiple fixtures or an entire hot-water side are affected, the common piping or valve path may need assessment before a shower repair is selected.

A serviceable showerhead differs from a concealed mixing valve or a discontinued cartridge.

Existing access panels and compatible trim affect how the valve can be inspected and serviced.
Whether The Symptom Is Shared
A single shower issue and a hot-water or whole-house flow problem need different diagnostic scopes.

GOOD TO KNOW
Low Shower Water Pressure
Questions Answered.
Have a question about your plumbing? These answers cover what we’re often asked.
Why did my shower pressure suddenly drop?
A sudden change can follow debris in the showerhead or valve, a supply change, or recent plumbing work. Comparing other fixtures helps distinguish a shower-only issue.
Can a showerhead cause low water pressure?
Yes. Mineral buildup or debris can restrict the outlet. If cleaning does not explain the symptom, the valve and supply path may need inspection.
Why is shower flow weak but the bathroom sink is fine?
That pattern can point to the showerhead, mixing valve, or shower branch. The sink gives a useful comparison but does not by itself identify which shower component has failed.
Does low pressure mean the shower valve needs replacement?
Not automatically. The restriction may be serviceable at the head or cartridge, and replacement depends on the valve condition, compatibility, and access.
