Swimming Pools – What To Consider Before Taking a Plunge On Building Your Home Spa

What size pool pump should I use.

salt water chlorinators for poolsPlease note this information is provided as a guide and is not a substitute for professional advice whatever you do with your pool you do at your own risk.

Key point: Choose the correct size pump bigger is not better.

When your pool was built your pool builder would have correctly sized the pump for your pool. If no equipment has been changed since pool was built the pump will be the right size. Unfortunately this is not always the case so you will need to check what size pool pump you have and compare it to what size would generally be used for that pool.

Most people think you select your poor pump size according to how much water is in the pool this is not the full story.

You actually need to size your pump to the filter that is being used in the pool and this is far more important for the following reasons.

1 A pump that is too large for a sand filter will not filter properly, the water passes across the sand with too much velocity and actually creates vertical channels in the sand bed, the high-speed water passes down these channels and does not get filtered by the sand.
2. A pump that is too large for a sand filter will also cause there to be too much pressure on the tank of the sand filter this can cause premature failure of the tank and laterals, the extra backpressure will also cause premature failure of the pump.
3. A pump that is too small for a sand filter will not backwash properly meaning the sand will not be lifted and cleaned once a month as it should be. The sand then becomes partially blocked and the system runs under too much pressure causing problems.
4. A pump that is too small for a sand filter can also result in a pool with low water turnover and dead zones in the pool which is often observed as algae in the corners or steps, if the pool has a salt chlorinator cell may not fill with water and the chlorinator will then turn automatically off and stop making chlorine.
5. Similarly cartridge filters will be under too much pressure if the pump is too large and the tank will fail prematurely. The cartridge element itself will also fail prematurely.
6. A pump that is too small for a cartridge filter is not as big an issue except for insufficient turnover of pool water and if it is a saltwater pool this cell may not filled with water properly and stop producing chlorine.

Getting Planning Permission for a Home Renovation

Back in the days before planning permission was required to make adjustments to a home, people were modifying their homes all the time, sometimes with disastrous consequences. The whole reason that you need to get planning permission isn’t to make your renovation process any harder; it’s simply a case of health and safety and ensuring heavy equipment users have the right construction licenses. If you modify your home in a certain way, it may lead to damage being caused if too much pressure is placed on certain foundations, or in other cases it could result in a neighbour suffering. In addition it is also necessary to ensure that any contractors carry full civil construction course verification in the form of correct builders licenses etc.

That’s what makes planning permission such a priority for even the smallest of renovations. So how can you go about getting planning permission for your home renovation and what can you expect the process to consist of? Let’s take a look at the details involved in obtaining permission and how to go about being approved.

The first thing that you’ll need to do is decide on the type of renovation that you’re intending to undertake. If it’s a small renovation (knocking through a wall, adding a doorway, installing a wall for windows), then you’ll need to detail the size, estimated duration and other finer details to your local government authority or establishment to gain approval. This won’t always result in a home visit, but these may sometimes be necessary to fully understand the renovation.

If you are intending a larger scale renovation (construction a new room, a conservatory or an extension), then you’ll need to book an evaluation with your local authority in charge of planning permission. They will attend and evaluate your property, or more specifically the location that you are planning the renovation. Once the renovation is fully understood, your case will be considered and you will be accepted or rejected.

So how long can you expect to wait for your renovation to be approved or rejected? Well this will vary depending on your location and the amount of work needed to evaluate your renovation, but the time is typically between a week and a month. If you find that your planning permission hasn’t been rejected, then you are entitled to query the reason for the rejection and then if possible. If the reason is something that you can alter (perhaps the time is a factor, or maybe the size of your renovation will impact your neighbours), then you are permitted to change your plans to suit and then resubmit for consideration.

If you find that your request for permission is continually denied, then it may be a case that the renovation cannot proceed as you originally intended. There are certain ways around this, but most of the time a home owner may have to submit and accept that they cannot legally go ahead with their intended renovation. It is always a good idea to find out the guidelines and policies as laid out by your local authority and stick to them as much as possible.
