@mmarto. Pressure control can be done using the diameter of the pipes. Get a good plumber who knows how to play with the diameters to create the pressure effect.



@ a4architect.com, thx. However plumbing was done kitambo before i took residency. The piping used is 3/4 inch. A mistake i must have made was to use the rectangular water tank instead of the cylindrical one. anyway i cannot change some of this now but was hoping to find a way of increasing pressure of my taps/shower.


@mmarto, an experienced plumber can change/alter pressure simply by replacing your entry/exit pipe sizes, not the whole plumbing works. With replacement at the exit of tank and entry of tap, this would do but only done by experienced professional plumbers who can play with the diameters to achieve this.


@ a4architect.com, could you suggest such ones. I have brought in so many to assist but none has been able. naomba serikali ya wazua inisaidie tafadhali. martin dot mose at gmail
The only time you should be looking down on others is when you are helping them up.

@mmarto – What type of mixers do you have? If you have installed those lever type mixers, these require high pressure.. achieved by installing an on-line water pump.
Again on constant pressure – I think you meant balanced pressure - this just means pressure of water in cold and hot water lines must be equal, for proportionate mixing at the mixer…


@limanika, i meant constant pressure. The issue is not the mixers coz pressure is not much from the naked pipe. I think the rectangular tank is the problem. i saw an article in the DN to do with constant pressure gadget starting at 3K. The article was written by a person working for Davis & Shirtliff

OK, in that case, most likely the gentleman meant to say the pump is able to maintain constant pressure at discharge regardless of the flow rate. This jargon is no answer to your situation..
@A4architect has a point.. if mixer is not an issue then the answer to your problem lies with pipework sizing and tank type. Best of luck, hope you get a good plumber to sort out…

Continuing with a somewhat related issue, Can those of you with solar water heaters share your experience?

Cost?
Performance?
Reliability? especially in cold places such as areas near the aberdares?
Drawbacks?

Especially in the recent cold weather. Am thinking of getting one and doing away with the instant showers but scared of the performance in July weather

I understand. Currently, its not easy to find an educated and experienced plumber, carpenter/fittings/electrical and structural guy.
Quacks have invaded and completely demoralized them to extinction.
Colleges are no longer training them and the few in the market have been reduced through natural attrition.
I can email you contacts of a Mechanical Engineer for Building services. The work is too small or him though but am sure he can give consulting advisory to your plumber.

The simplest solution is just to raise the tank a few meters above its current position....works best but may be a little more costly!

My overhead Lorenzetti intant shower used not to work, my plumber blamed the airlocks...it still didnt work or worked occasionally especially when the tank was full.
I raised the tank 4 metres high and now both instant shower settings works perfect as if supplied directly from a kanjo water-line.

Did you construct an external support structure to achieve the 4 metres- assuming it is not possible to get additional 4 metres inside the typical roof void?

My tank is actually outside the roof, did a simple concrte plus steel structure to prop it up approx 4 meters just above the lintel(spl) height!
Works perfect so far...even in the kitchen taps are running fast and wenye jikoni are also happy!
