Flow rate restrictor on shower panel


I have a vigo rain shower panel. The pressure isn’t good in the current setting. I can replace the flow rate restrictor - going from 2.0 Gpm to 2.5 gpm. Or I can have no flow rate restrictor in there.

Vigo tech support suggested having no restrictor in there could damage the shower panel hardware.


Thoughts? Is there an after market restrictor that runs higher than 2.5gpm?

Re: Flow rate restrictor on shower panel


I think you talked to someone that is not knowleageable.

I cant think of anything that would be made so weak that it would be a problem. Did you ask him what hardware it could damage. Bet he does not know.
I say just remove it. I never thought flow restrictors were a good idea. If I want less pressure I will just turn down the valve.

Most just install because of government regulations. And then people like me just remove them before we install.

It was the tech support guy at Vigo. He said it “may” damage the hardware.

Re: Flow rate restrictor on shower panel


the pressure observed by the system without a flow restrictor won't be all that much greater than the pressure observed with one. If these are tested to typical standards ASME 112.18.1, they are tested at 125psi. Your plumbing system typically doesn't see anything near that, as I think most homes are around 30-70psi, depending on your elevation in relation to your water source. I'd take out the flow restrictor and see how you like it. Is there some other kind of filter in the unit before/after the flow restrictor?

Re: Flow rate restrictor on shower panel


A flow rate restrictor restricts the flow or volume not the pressure.

Remove it.

Re: Flow rate restrictor on shower panel


But also there is the problem with a larger shower head like you have. Or when people try to install some of these that have a few nozzles.

I myself like a lot of pressure when I take a shower. Most house dont really have enough pressure to feed these types without lowering the pressure because of larger or more heads.
So just not for me.

How large is your drain? Sounds like vigo voids warranty.

What does the drain have to do with anything?
This does not change the drain. Which is sized to take the full volume that the house can supply.

Re: Flow rate restrictor on shower panel


Because if you increase the GPM output of your shower heads your drain must be sized to take the water. Pipes can only do so much. It isn't magic its physics.

2” drain. My curb is 6” tall. Not really worried about flooding my bathroom.

No. The drain is already sized for the max flow the whole house can provide. Even if every faucet was on and ran to the shower drain. Even oversized at that.

You are saying if you put in a low flow showerhead. And then later put in a full flow or no shower head. That you would increase the drain size. Makes no sense.

That is why you will never see a house faucet or showerhead of any type that tells you to check your drain size before you install.

The city water meter will only allow so much flow.
