Is my swimming pool pipe 1.5 inch or 2 inch?

Wednesday, May 22nd, 2013

One thing that always confuses swimming pool owners is the size of the pipe work on their pool. This is because pipes that are called inch and a half are nearer 2 inches when you put a tape on them. With this article we hope to clear up the confusion.

The first thing to know about the pipes used on domestic UK swimming pools is that they have not gone “European” yet. Everything is in imperial. On the continent everything is in metric and metric pipes will not fit together with imperial pipes without an adaptor. The vast bulk of existing domestic swimming pools in the UK will have been constructed using “inch and a half” pipework. Some may have been built using 2 inch but they would generally be bigger pools. Nearly all pool equipment, pumps, heaters, filters etc are made with inch and a half fittings on them. But not all. Some pumps have 2 inch fittings as standard and so need to be adapted down to inch and a half.

So you would think that if you put a tape measure on your pipes you would see the pipe line up with the 1.5 inch mark on the tape – but it doesn’t.  I have to say that we don’t know why this is! What is known industry wide as inch and half pipe is actually just over 1 and 7/8ths wide on the outside diameter and about 1 and 5/8ths on the inside diameter.

"Inch and a half" pipe is actually nearer 2 inches

If you are looking at a coupler for inch and a half pipe then the inside diameter is a fraction under 2 inches and the outside diameter is 2 and 3/8ths inches. So a typical inch and a half fitting like a 90 bend is nearly 2 and a half inches wide!

To make matters even more confusing there are two types of pipes, one white and one grey in colour. The white ones are the most commonly used and they are made from ABS material known as “Class C ABS”.  ABS stands for Acrylonitril Butadiene Styrene. The grey coloured pipe is PVC (Poly Vinyl Chloride) but you can get white PVC also. You can join ABS to PVC but you need to be careful in your choice of glue. Some glues are ABS only, some glues are PVC only and some, like the one we sell, are suitable for both ABS and PVC.

Swimming Pool Design Awards

Friday, July 27th, 2012

The 2012 Swimming Pool “Masters of Design” Awards have been announced in America. The awards are split in to various categories and are only for pools in the United States. We thought you might like to see some photos of the pools. Some of them are not designed with sober European taste but they are all spectacular in their own way.

A Guide to Swimming Pool Coping Stones

Tuesday, April 24th, 2012

Just about every in-ground swimming pool has coping stones around the edge. Over the years they deteriorate and need replacing. This article will tell you what your options are for replacing them.

Until recently all Swimming pool coping stones were sourced from UK manufacturers but now a nice range of Mediterranean style copings are available in the UK. The traditional UK made coping stone comes  in 2 foot lengths and are either 9 inches or 12 inches wide. There are two stlyes and two colours available. The two stlyes are called “bullnose” and “flat top”. Bullnose have a built in backward slope and flat top do not. The colour choices are White or Buff. The most popular choice by far is White Bulnose.

As well as the standard straight coping you can also get what are known as “specials”. These are the corner stones for internal or external corners and “radius” copings for going around roman ends (as shown in the image above).

The traditional copings always stand out from the paving surround and many people like the way they define the edge of the pool but others prefer the copings to match the surrounding paving. This matching style is typically Mediterranean and now there is available in the UK a Spanish pool coping that is not only great looking as a stand alone coping but comes with matching paving slabs if you want them.

The Sahara coping has the built in back slope while the Ardoise coping is a flat top. Ardoise has a riven finish while the Sahara is smooth.

Sahara Coping - back sloping, smooth and 270mm or 330mm wide

Surprisingly these Mediterranean swimming pool coping stones are not more expensive than their UK counterparts.  Below are the prices for a 12ft x 24ft rectangular pool for comparison.

Traditional 9 inch £740 .00
Traditional 12 inch £920.00
Sahara 270mm £680.00
Sahara 330mm £740.00
Ardoise 330mm £930.00

I’ve bought an above ground pool – what else to I need?

Wednesday, July 28th, 2010

So you have bought an above ground pool for the garden, you have errected it and filled it with water – what now?

Well, first of all jump in and enjoy it! But you will need chemicals to keep the water clean and maybe you will want to warm the water up as well. This article will tell you what you should get.

Firstly when we say above ground pool for the garden we mean this sort of thing.

A pool with its own filter pump and paper filter cartridges. Although the pools above are the bigger type the advice here applies just as well to a pools down to 8ft round.

Keeping it clean

You are going to need to put chemicals in the water to keep it clean.  The easiest way to treat the pool with chemicals is just to drop a floating dispenser in the water. The Ficlor 5 Bouy is ideal. Turn the lid until the holes line up for your size of pool, drop it in the water and that is it. Take it out when you swim, put it back in when you have finished. Inside the 5 bouy are two types of chlorine and a clarifier to kill bacteria and algae and help the filter keep the water clear and clean.

The 5 bouy is ideal for the smallest pools up to about an 18ft round pool. From about a 15ft pool up to the biggest garden pools available you might want to put multifunctional granules in the pool. The granules come in  5kg tub and one tub should last a whole season. The granules contain chlorine to kill bacteria, an algicide and a clarifier to keep the water clear and clean. You will have to test the water to find out how much chlorine is in there and for that you need some 3 way test strips. They also test for pH (acidity) and alkalinity. For a small pool you don’t need to worry too much about the other two. Putting chlorine in a pool is a bit like putting petrol in a car, when the fuel gauge is low you put more in. Test your pool every day and when the reading is low put more chlorine in.

Keeping it warm

Left alone the water in your pool will warm up and cool down each day with the warmth of the day and the cool of night and as the weather generally gets warmer so will the pool.  If you want warmer water than nature gives you then the first thing to buy is a solar cover. This is made with bubbles to make it float on the surface, it insulates the water and has a greenhouse effect of letting the sun’s ray penetrate to warm the water but retaining the heat at the same time. A good solar cover will keep the water about 3 to 5c higher than it would have been without one but the water temperature will still rise and fall with day and night and warm and cool weather.

If  you want your water to always be warm no matter what the weather then you will have to have a heater as well as a solar cover. For pools up to 12ft this is quite easy. You can buy the Intex 3kw heater or the better quality Elecro 3kw heater. 3kw is as much as you can run from a plug socket in the wall so the 3kw heater is a popular size. If your pool is bigger than 12ft then you should buy the 6 or 9kw heater. These have to wired in by an electrician. Above 9kw you will struggle to have enough electric capacity in your house for a bigger heater. Once you get in to the realms of the 12ft x 24ft you should be thinking about a heat pump. These things consume less than 3kw and so can be plugged in to the wall but they generate up to 12kw of heat.  Although they are much more expensive than an Elecro heater they will pay back in electricity savings in two years or less.
