I would like to use my 20 years of experience to help those who are just starting out in the exciting world of home improvement and in particular in designing their perfect bathroom.
Over the years, clients have been disappointed when I’ve had to say ‘no’ to some of their bathroom designs simply because they violate the laws of physics. Although some solutions are possible, they can add significant amounts to the cost of a remodel. Hopefully this article will help people think about the problems that occur in the process.
* Relocation of Sanitary Items Inside the Bathroom
* Sewage water
Before making any decision on the location of any bathroom fixtures, it is best to start at the beginning, taking water services into account.
If your intentions are to reposition a bathtub or sink, you should always take into account the wastewater outlet. Existing positions are conveniently located for sewage outlets, so moving positions will sometimes complicate sewage disposal. The thing to remember is that you must always have a drop in the pipe for wastewater to flow from the appliance into the drain pipe or this could mean you would have to raise the tub or shower on a platform to maintain the correct slope. which should be and average of 1:80.
If there is more than one outlet in a waste line, you will probably need to install an air bypass valve. For example, if a bathtub and sink are connected to the same drain line and a bypass valve is not installed, the pressure created by draining the bathtub could suck water out of the sink trap, causing odors to come from the drains. through the sink plug hole. Sink traps are available with an already built-in air bypass valve for these scenarios or can be purchased separately if preferred.
Modern toilets can also present the same problems with drain pipe gradients, as all drain pipes will end up attached to the internal drain basin, although in older properties the toilet drain pipe normally runs through the wall into an external drain pipe and the sink and toilet go into a chute and then down the drains.
* Hot and cold water supplies
Connecting hot and cold water supplies to newly installed toilets should not be as difficult to install as sewage pipes because no slopes are required. You can supply these pipes under floors, in lofts or by casing them, although water pressure must be considered. For example, certain faucets and showers need a specific water pressure. Water pressure gauges to take these readings can be purchased at a cost of approximately £25.00 ($40.00).
The baths must always be fed by 22mm pipes to maintain the flow. If your water supply is a gravity fed system, the water pressure is governed by the height and size of the water tank found in your loft. If you increase the size or height of the tank, the pressure will increase. If you have a combination (combi) boiler system, the hot and cold water supplies have reduced main water supply pressure. You will need to check the specifications of the boiler.
Nothing disappoints more than having waterfall faucets (faucet) with low water pressure and no more than a trickle of water instead of the expected waterfall.
* Specifically Showers
Shower pumps are another thing that really needs to be considered due to the hot water supply pipe having to be taken from a Surrey flange directly from the top of the cylinder. A Surrey flange has piping that falls further into the cylinder than a standard flange, ensuring the pump does not draw air from the top of the cylinder. Some pumps can pump water faster than the header tank can fill the cylinder, hence the need for the Surrey flange. An alternative is to fit an essex flange, but that would mean drilling into the side of the cylinder which most plumbers frown on due to possible ruin of the cylinder.
If you are thinking of installing a hydromassage shower, there are modern showers that incorporate a pump into their system, for example Aqualisa Quartz Digital, which is easy to install and plumbing.
A worthwhile consideration when installing a new shower and enclosure in your new design is the weight of the shower pan. Large stone shower trays may require two people to lift and install and additional weight on the bathroom floor above must be considered. There are more modern acrylic-coated stone shower trays that are about half the weight and just as rigid, but a bit more expensive.
* Access and maintenance
Please note that when all pipes and connections are being run, access to these pipes for maintenance should always be considered. For example, it would be better for pipes that have been boxed to have weld joints rather than compression joints to minimize the risk of leaks and the need to deconstruct the box to get to that leak. Access panels can be purchased and incorporated into the fence installation.
If you choose to tile your bathroom panel, it’s always worth remembering that the faucets may need replacement or maintenance, so the panel will need to be removed at some point.
All faucets and shower connections must have isolation valves installed. Full port valves are the most suitable for maintaining flow. Some appliances will need double check valves fitted, eg bidets, but this will reduce the flow rate.
All copper piping must be electrically grounded and crossovered.
I would always recommend using name brand products for parts, reliability and performance and quality of finish.
