When my daughter's family bought a RV last year, they bought a (rather expensive) surge protector and a water pressure regulator. The surge protector does not "turn on" until it see several minutes of constant voltage, which will catch you unless you remember this. The pressure regulator result in low volume/pressure at the faucets inside.I can kind of understand the surge protector but I never used a water pressure regulator back when I was an active camper.How many do or do NOT use a water pressure regulator ?Are there good ones that do not result in low volume/pressure ?

It all depends on.1. The amount of water pressure your system can handel.2. The water pressure of the supply you are connected to.If you do not know what the water pressure is at the park you are at. Use the pressure regulator.If it is not to high then you don't need it and if you use it you will get less pressure.I have been in Parks where the water pressure was over 100lbs. Most are under 50 lbs.

My regulator was for 40 psi. That is plenty of pressure and way more than provided by the pump when not hooked up. I would rather have low pressure than blown fitting due to excessive pressure.Actually I go one step further. I rarely camp where there are hook ups and I stopped hooking up even if city water is available. I fill my tank and use the RV water pump. That not only keeps the pressure down but it makes sure the water in my tank does not become stale and does not grow mold.

A good pressure regulator does not reduce flow. I use a Watts set at 53#. That with an Oygenics shower head gives me a shower like at home. There are cheaper regulators than the Watts that work well. Most of the adjustable regulators will outperform the preset ones. I don't hook up to a water source without it.

I have a Watts adjustable water pressure regulator......4 gpm max flow and I keep it set to 50# static pressure.Never had/used a regulator before as camping was rarely at any place that had continuous water hookup.But when we went FT I got one based on reports of CGs having high pressure.....which we did find true.But after a little more then a year on the road we stopped using 'city water' connections due to a fitting failure in the middle of the night (fitting must have been cracked during original install and then finally blew apart).$6000 in damages/costs---we went back to using fresh water tank and pump which has a 45# discharge and 'cycles' should a leak begin.IF one is going to connect to 'city water' then it is good idea to have/use a good quality water pressure regulator at the source to mitigate high pressure excursions at CGs

First, typical water pressure in S&B is usually between 80-100 psi while in a TT between 40-60 psi. The TT has flexible plastic pipes so it can't that high pressure supplied in many campgrounds therefore an add-on external pressure regulator is highly recommended.Second, there are two types of pressure regulators - adjustable and non-adjustable. Non-adjustable ones are the cheapest and most commonly used. They output pressure typically at 40-50 psi. The adjustable ones will output at any pressure up to the supply line pressure. At 40-50 psi, both regulators will output very similar amounts of water. So if you want more water volume go with an adjustable regulator set to a higher pressure.Third, be sure to attach your regulator directly to the campground supply spigot and then attach your water hose to the regulator. If you attach the water hose first, you may get a water leak at both ends of the hose.

I suspect you have a restricted faucet not a pressure problem. Remember that pressure and volume are two different things. You can have high volume with low pressure and visa versa. An "expensive" regulator should not affect volume. Pipe obstructions are the cause of low flow, if the source has good volume.

Check the screens on the regulator, inlets, and faucets.

If your flow is restricted with both the fresh tank pump and street spigot then it is likely inside faucets. If it is only restricted with the street supply and regulator then it is likely the screens in the hose or regulator to the RV.

My previous used RV came with a nice looking but unbranded brass pressure regulator that SERIOUSLY lowered pressure and volume. After suffering with that for several trips I bought a similar looking Camco brand from Amazon and the problem was gone! Looking inside both, the unbranded one seemed to have much smaller passages for water to pass through. It certainly would have protected my RV plumbing but with aggravating results! Not all regulators are the same although they may look similar.

I use a vaterra pressure reg, I had a white rv hose swell up so much I thought the hose ate a rabbit
