How to Improve Flow in Delta Rain Shower Head?

Delta rain shower heads are one of the common showerheads in the market and the best. One problem with these designs is that they experience a pressure drop if the height is too high, and with the pressure changes, it can turn your morning showers into a mess. So, improving the Delta rain shower flow is important and requires some ideas to ensure that any step you make doesn’t interfere with the strength and shower discharge. The guide will explain all the steps to improve water flow in your Delta rain shower head for a better discharge.

Why Do You Need to Improve the Shower Flow?

There are many reasons you should work to ensure that your Delta shower head has the right flow. Here are some key reasons you need to develop a way to improve and ensure you have constant water flow.

To improve water Discharge.

Water flow/discharge is the amount of water coming out from your shower head per second; most designs are calibrated to offer an ideal discharge to ensure a continuous flow of the same. But this factor is affected by pressure drop and pressure from basic theoretical physics; pressure is affected by depth, and by saying depth, we mean the showerhead’s height. The water’s potential energy is also affected by different height, resulting in a difference in water flow. To achieve all of this in a constant flow, one has to find a way to improve any Delta shower head height for constant water flow.

Reduce Power Costs

If you are using a pump to pump your water to your showers, then an improvised Delta shower head with good installation will consume less power to deliver water to your shower. Any shift or wrong installations will force the pump to overwork and consume a lot of energy. The only solution/answer to this is to ensure that you improve the shower flow and install it to work with the forces of nature.

Proper Functioning

Improving your Delta shower head water flow makes it easier for kids and other persons with disabilities to enjoy the shower even with less water supply. Maximizing shower flows also helps to ensure there is a full discharge making your shower enjoyable and continuous.

How to Improve Flow in Delta Rain Shower Head?

There are some key parts in your shower system that you should set to achieve; some of those parts are as follows.

1 Flow Restrictors

Use a pipe wrench/thread cutter or a pair of wide locking pliers and a rag to set the restrictor. Many Delta shower heads are equipped with a flow restrictor that helps the user regulate the amount of water. The flow control is typically white or black plastic disk with a through a hole in the middle. For your shower to operate, water has to pass through this point, and if you are getting less, it means this part isn’t in its full limit; you can turn it clockwise. But if you are getting an excess discharge, then turn your restrictor to the left or anti-clockwise. At all costs, if your shower head is experiencing either an excess or less discharge, then this is your control point.

2 Amplifying Showerhead

Most of the home water supply is supplied with a low-pressure pump to prevent damages to home appliances, and due to this, your showerhead might have less water. Water pressure is always set at the water reservoir, and if you own your home pump, you can step up the discharge. If you cannot change the water pressure, then it is wise to consider amplifying showerheads. This is meant to store water in a tank then pump it when the tank is full, making the water’s velocity to increase any time the pressure is turned on in the water supply tank in your town. Here are some installation procedure;

  • With your shower head extension, stick a junction tank or an elbow that will help collect water for your amplifying tank.
  • Use a pipe wrench to cut for threads and other fittings.
  • Ensure you have a direct connection from your main shower system your new extra Delta tank
  • Open your amplifying shower head and then read on the manual specifications for more directions.

3 Check Water Volume

The pressure is affected by velocity and depth, and the only way your Delta shower head does not have the right discharge is either there is less water in your tank or in the reservoir. Before any step, try to find out if you have enough water and if your tanks are full and still the flow is weak, consider the following.

  • Open the gate valve by turning the clock handle counterclockwise.
  • Check if the pressure gauge is working or if there is enough pressure in the pump.
  • If you have less than 30 pounders per square little, your pump needs a replacement; the minimum required pressure is 45 pounds per square.

4 Dirty Showerhead

Your shower might experience less discharge due to clogging leaves and sand in the pipes; it is then wise to check before running any diagnostic or troubleshooting process. Chances are most of your lines have clogged leaves and other material preventing water from reaching your shower heard. Magnesium and calcium are hard water compounds that leave deposits on your pipes and always turn your pipe into a filter. If your showerhead has some of these deposits, then you can use vinegar or lime to clean your showerheads and increase the water flow.

  • Prepare a solution of vinegar and lime, then dip your showerheads for 30 minutes.
  • If the scary deposit doesn’t disappear, then use a brush to scrub your showerheads until you have a clean and free discharge pipe.
