I am using a custom page template for my portfolio.  The code is calling the correct number of posts per page but for some reason the pagination links won't show up :-S

My query

&lt;?php 
    $loop = new WP_Query(array('post_type' =&gt; 'portfolio', 'posts_per_page' =&gt; 2)); 
?&gt;
&lt;?php while ( $loop-&gt;have_posts() ) : $loop-&gt;the_post(); ?&gt;
&lt;?php   
    $custom = get_post_custom($post-&gt;ID);
    $screenshot_url = $custom["screenshot_url"][0];
    $website_url = $custom["website_url"][0];
?&gt;


The entire markup

&lt;?php
/*
Template Name: Portfolio
*/
?&gt;

&lt;?php get_header(); ?&gt;

&lt;div id="full_container"&gt;
&lt;div id="portfolio_content"&gt;
&lt;div id="portfolio_wrap"&gt;
&lt;div id="content"&gt;

    &lt;?php 
        $loop = new WP_Query(array('post_type' =&gt; 'portfolio', 'posts_per_page' =&gt; 2)); 
    ?&gt;
    &lt;?php while ( $loop-&gt;have_posts() ) : $loop-&gt;the_post(); ?&gt;
    &lt;?php   
        $custom = get_post_custom($post-&gt;ID);
        $screenshot_url = $custom["screenshot_url"][0];
        $website_url = $custom["website_url"][0];
    ?&gt;


&lt;a href="&lt;?php the_permalink() ?&gt;"&gt;

&lt;span class="img"&gt;
&lt;?php if ( has_post_thumbnail() ) { the_post_thumbnail( 'thmb-portfolio' ); } ?&gt;

&lt;span class="under"&gt;
&lt;!-- Excerpt title --&gt;
&lt;span class="title"&gt;&lt;?php the_title(); ?&gt;&lt;/span&gt;

&lt;!-- Excerpt description --&gt;
&lt;span class="desc"&gt;
    &lt;?php my_excerpt('short'); ?&gt;
&lt;/span&gt;
&lt;/span&gt;
&lt;/span&gt;
&lt;/a&gt;


        &lt;?php endwhile; ?&gt;  

&lt;!-- Next/Previous Posts --&gt;
&lt;?php if (function_exists("pagination")) {
    pagination($additional_loop-&gt;max_num_pages);
} ?&gt;

&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;

&lt;?php get_footer(); ?&gt;



Question: How can I prevent the intake vent for an on demand water heater from getting plugged?
Answer: Picture of the vents would help. The way I've usually seen them installed is with a 90deg elbow on the intake so that it points down. That would prevent snow from clogging it.

The exhaust vent pipe usually has a 90 deg elbow so that it points up. You can get a rain cap for the end of it to keep rain/snow out.

Looking at this document from your manufacturer it shows one of the vents elbowed to face down like I indicated the other one isn't.

After seeing the pictures of your vents it looks like you can elbow the one on the right and then get a hooded cap for the one on the right. Something like the Noritz PVT-HL looks like it might work.

Then you can install a tighter mesh to keep the wasps out.

By the way, have you tried those wasp deterrents that look like nests? I haven't but they seem to have good reviews.
